2021In the first half of the year, the investment in water treatment industry projects was 180 billion yuan, a year-on-year decrease of 48.7%.

In the first half of this year, water treatment projects were mainly concentrated in southern China, with investment in industry projects of 109.3 billion yuan.

The downstream customers of the water treatment industry are mainly electric power, metallurgy, chemical, municipal water affairs and other industries. The prosperity of these industries is closely related to the development of the national economy and the fluctuation of fixed asset investment. Due to a certain degree of volatility in my country's macroeconomic development, the government will take stricter macroeconomic control measures for a certain period of time, and even directly restrict the scale and progress of fixed asset investment in specific industries, making the water treatment industry directly or indirectly affected by the macroeconomic The impact of economic cyclical fluctuations.

According to the data from China.com, the investment in water treatment industry projects in the first half of 2021 was 180 billion yuan, a year-on-year decrease of 48.7%. From a regional perspective, the decline was mainly concentrated in the northeast, north, northwest, and East China, Southwest, and Central China, while South China grew significantly, the project investment increased by 39.6%.

In the first half of 2021, the investment in water treatment projects in South China was 109.3 billion yuan, accounting for 61% of the national water treatment industry project investment, followed by 25.8 billion yuan in Central China, accounting for 14%, and East China 20.5 billion yuan. Than 12%.

At the same time, starting from July 1, 2021, "Rural Sewage Purification Device" (JB/T 14095-2020), "Water Pollutant Discharge Standard for Electronic Industry" (GB 39731-2020), "Medical Waste Treatment and Disposal Pollution Policies and standards such as Control Standards (GB 39707-2020) and Hebei's "Operational Procedures for Limited Space Operation of Municipal Drainage Facilities" have been implemented. Project investment in the water treatment industry is expected to increase in the second half of the year.

Sewage treatment will develop in the future

1. The trend of centralized governance in industrial parks is obvious

With the needs of economic development and environmental governance in various regions, many provinces and cities have put forward the industrial development strategy of "retreating from the city to the park" to increase the centralized pollution control and treatment of the enterprise groups in the industrial park, and water treatment Services have also shifted from being a point source for a single enterprise to the systemic governance of the entire park, as well as the development of comprehensive utilization of water resources. With the expansion of the number and scale of industrial parks and the improvement of industrial wastewater treatment standards, the integrated water treatment business of the industrial parks will There is a huge market space.

2. New technologies in the sewage treatment industry

At present, eutrophication of water bodies has become the norm. For the treatment of pollutant nitrogen, nitrification-denitrification is generally used to complete the denitrification. However, in this process, a large amount of aeration energy consumption and organic carbon sources are consumed, which will not only cause higher costs, but may also cause secondary Pollution, and anammox technology can improve efficiency on the basis of maintaining low costs. At the same time, simultaneous nitrification and denitrification can reduce the demand for carbon sources in sewage treatment, save energy consumption for aeration, and reduce sludge production. It is also a new technology for energy saving and consumption reduction of sewage. The core difficulty is still not precisely controlling the reaction conditions to meet the needs of overall aerobic and partial hypoxia. The biofilm method is one of the effective ways to realize simultaneous nitrification and denitrification.

3. The market for advanced environmental protection technology and equipment is gradually taking shape

A standardized and complete set of sewage treatment equipment market has gradually formed. Compared with sewage treatment engineering enterprises, it has the advantages of short production cycle, low investment cost, small floor space, and quicker commissioning, which is conducive to building a water city compatible The ecological system is highly compatible with my country's current sewage treatment needs.

4. Sewage treatment gradually forms a new artificial intelligence operation system

As artificial intelligence and Internet of Things technologies are gradually applied to the sewage treatment industry, through the establishment of a smart water cloud platform, the sewage plant can control the operation status in real time through the smart water cloud platform, and improve the convenience and timeliness of the operation and management of the sewage plant. The cloud platform is supported by cloud services, Internet of Things, artificial intelligence algorithms and other technologies. It uses the data of a single or multiple wastewater treatment plants as a collection, combined with technology and artificial intelligence algorithms, to provide wastewater treatment plant operation prediction and control optimization, and maintain stability and reach the standard Low energy consumption operation.

5. Realize energy own and even energy output

Through the continuous innovation of sewage treatment technology, the future technological development direction of sewage treatment plants is to realize the energy of sewage treatment plants and even energy output, that is, the application of new technologies, sewage treatment plants will no longer be an energy consumption unit, and It is through the application of innovative technology to realize energy conversion, and finally realize energy self-sufficiency and even realize energy export.
