In May of this year, an article entitled "Sewage Plant Drinks "Tsingtao Beer"! "Misplaced Resources" Gives Qingdao Plan" (click to review) report,It is mentioned that Tsingtao Brewery Co., Ltd. Tsingtao Brewery, Tsingtao Brewery No. 3, and Tsingtao Brewery No. 4 have signed agreements with Qingdao Tuandao Sewage Treatment Plant, Qingdao Chongjie Environmental Pingdu Sewage Treatment Co., Ltd. and Qingdao Capital Ruihai Water Co., Ltd. According to the strategic cooperation agreement, the production wastewater of the brewery can be discharged into the sewage pipe network in accordance with the agreed concentration limits of the main pollutants after simple pretreatment, and is no longer subject to the restriction of the sewage discharge standards of the pipeline. After the agreement is signed, the above three breweries will provide carbon sources for three downstream sewage treatment companies. In this way, the three sewage treatment companies will save about 6 million yuan in carbon source purchase costs and reduce carbon emissions by 5,000 tons each year.

Recently, another sewage treatment plant also "drank" Tsingtao Beer...

Hubei Huangshi Sewage Treatment Plant "drank" Tsingtao Beer

On the morning of August 16, 2021, the water outlet monitoring data of Tsingtao Brewery (Huangshi) Co., Ltd. showed: ammonia nitrogen (mg/L) 11.48, chemical oxygen demand (mg/L) 344.22, total phosphorus (mg/L) 1.78. What is different from the past is that the Tsingtao Brewery production wastewater is pretreated and discharged into the municipal sewage pipe network in accordance with the agreed discharge standards, and finally collected and treated by the Huangshi MCC Water Affairs Group Chengshan Sewage Treatment Plant, which marks the production wastewater resources of Huangshi City's enterprises. A solid step has been taken in the utilization of innovative practices.

The Huangshi MCC Water Group Chengshan Sewage Treatment Plant has a designed processing capacity of 40,000 tons per day. It is responsible for the collection and treatment of domestic sewage in the Tuanchengshan area and is an important public infrastructure service facility. The sewage treatment plant of Tsingtao Brewery Yellowstone Co., Ltd. has been built and operated for 18 years, with a design treatment capacity of 4,000 kiloliters per day.

How are the two companies that seem to have few intersections closely linked?

Urban sewage treatment plants adopt the activated sludge process. The activated sludge is composed of a large number of domesticated and proliferated microorganisms and bacteria. The growth and metabolism process of microorganisms uses carbon, nitrogen, and phosphorus in the sewage as food, and it grows and metabolizes while removing carbon, Pollutants such as nitrogen and phosphorus complete the sewage purification process. The "carbon" here refers to the rapidly degradable organic matter. Insufficient "carbon source" in sewage will affect the efficiency of nitrogen and phosphorus removal. The beer production wastewater has a high concentration of organic matter, has good biodegradability, does not contain toxic and harmful substances, and is an excellent supplement to the "carbon source" of the sewage plant.

In December last year, the Ministry of Ecology and Environment and the State Administration for Market Supervision and Administration jointly issued the amendments to the "Beer Industry Pollutant Discharge Standards" (GB19821-2005), which clarified that "wastewater from wine enterprises can stably supplement high-quality wastewater treatment plants. Carbon sources, coordinated to promote the stable operation of sewage treatment plants. Allow alcohol manufacturers and downstream sewage treatment plants to sign legally effective written contracts to jointly agree on the concentration limits of water pollutants, and serve as the basis for environmental supervision and law enforcement.

Take advantage of the opportunity of the release of the new policy interpretation, combined with the party history study and education "I do practical things for the masses" practical activities, Huangshi City Ecological Environment Bureau Xialu District Bureau united with the Municipal Drainage Management Office, starting from solving the actual problems of the enterprise, Matching bridges between the two enterprises, promoting enterprise cooperation, and providing services for the enterprises through organizing seminars, investigating the municipal pipeline network, reviewing the feasibility of the scheme by experts, and assisting in the filing of changes in pollution discharge permits.

After the active promotion of Huangshi City Ecological Environment Bureau Xialu District Bureau and Huangshi City Drainage Management Office, in August this year, Tsingtao Brewery (Huangshi) Co., Ltd. officially discharged the sewage pipe network directly in accordance with the agreed standards. The agreement standards agreed by the two parties for filing will also become a new law enforcement basis for the environmental protection department on corporate wastewater discharge. This is also an attempt by Huangshi City to use wastewater as a resource to achieve green, low-carbon and sustainable development.

According to Xu Weijiang, the person in charge of the Safety and Environmental Protection Department of Tsingtao Brewery (Huangshi) Co., Ltd., in order to ensure the safety of sewage discharge, the company currently extracts 50% of the sewage The wastewater is mixed and discharged into the municipal pipe network, and then enters the Tuanchengshan Sewage Treatment Plant for reprocessing.

The company has also established a sewage emergency response plan, and in accordance with the principle of timeliness, gradually discharge all sewage from the plant area directly into the municipal pipe network, and uniformly treat it by the Tuanchengshan Sewage Treatment Plant. It is estimated that within one year, Tsingtao Brewery Yellowstone Co., Ltd. can save more than 200,000 yuan in wastewater treatment costs.

Suzhou Sewage Treatment Plant also drinks "Snow Beer"

On May 11, 2021, China Resources Snow Beer Suzhou Plant and Suzhou Industrial Park Qingyuan Huayan Water Co., Ltd. signed a production wastewater commissioned treatment agreement. Snow Beer's production wastewater is simply pretreated and discharged into the municipal government according to the agreed discharge standard. The sewage pipe network marks the beginning of the Suzhou Industrial Park's official start of innovative practices in the utilization of wastewater from production.

Qingyuan Huayan Water has two integrated urban sewage treatment plants with a designed processing capacity of 500,000 cubic meters per day. They are responsible for the collection and treatment of domestic sewage and production wastewater in the Suzhou Industrial Park. They are important public infrastructure service facilities.

China Resources Snow Beer Suzhou factory, established in 1997, is one of the first companies to settle in the park. The factory adopts malt fermentation technology and has an annual beer production capacity of 300,000 tons.

Suzhou Industrial Park Eco-Environment Bureau (Water Affairs Bureau) bridged the gap between the two companies. At present, online monitoring instruments and metering devices have been confirmed. Snow Beer's production wastewater is officially discharged into the sewage pipe network in accordance with the agreement standard, which is truly "Carbon" turns waste into treasure.

It is estimated that in the next year, China Resources Snow Beer can save more than 1.2 million yuan in sewage treatment costs. The sewage treatment plant uses beer wastewater as a carbon source to improve the removal efficiency of sewage nitrogen and phosphorus. In theory, it can increase the total nitrogen reduction by 355 tons per year. The coordinated and sustainable development of the environment, society and economy has been truly realized.

Changzhou sewage treatment wears "green clothes" and drinks "beer"

On August 28th, in the Changzhou Sewage Treatment Plant located on the Yangtze River, the scene of sewage treatment wearing "green clothes" and drinking "beer" was impressive.

In March 2021, Changzhou City Drainage Management Office took the lead in Jiangsu Province to sign a production wastewater commissioned treatment agreement with China Resources Snow Brewery (Changzhou) Co., Ltd., and the brewery production wastewater was discharged into the agreed discharge standard after simple pretreatment. Municipal sewage pipe network.

Data shows that in the second quarter of 2021 alone, Snow Brewery (Changzhou) produced a total of 35,730 tons of wastewater. According to the new management model, the brewery reduced operating costs by 125,000 yuan.

The Changzhou Riverside Sewage Treatment Plant uses beer wastewater as a carbon source. While increasing the nitrogen and phosphorus removal rate of the sewage, it actually reduces the purchase of commercial carbon sources by 450,000 yuan, reducing carbon emissions by 220 tons; it is expected to reduce the purchase of carbon throughout the year Sourced 1.5 million yuan, reducing carbon emissions by 730 tons. The Changzhou Sewage Treatment Plant really put on the "green jacket" of energy saving and emission reduction, and drank the "beer" happily.
