Review on the Development of Water Pollution Control Industry in 2020 and the Outlook in 2021
The year 2021 marks the beginning of the 14th Five-Year Plan. Overall control on water resources, water ecology, and water environment will further release the market demand for water governance. For that, in the long run, the water treatment technology will be surrounding the following 4 dimensions.
- Key Components, Materials and Medicament in Environment Protection Facilities
- Whole Process Management of Fixed Source Pollution Sources and Collaborative Control of Multiple Pollutants
- Land and Sea Coordination, River Basin and Regional Pollution Control
- Coordinated Prevention and Control of Groundwater Pollution, Surface Water Pollution and Soil Pollution
2020 was the year of assessing the effectiveness of the “tough battle against pollution” and planning for the Eco-civilization construction in the 14th five-year Plan period. This year, the CCCP of China has proposed the major task of continuously improving the environment. Water treatment enterprises are consistent with the CCCP of China, not only have they contributed in the pandemic prevention and control, but also have done a good job in improving the water environment.
Policies and regulations favorable to the development of the environmental protection industry have been introduced this year, and they are as follows.
1, Policy Guarantee
the General Office of the CPC Central Committee and the State Office have issued the Guiding Opinions on Building a Modern Environmental Governance System and the Assessment Measures for the Effectiveness of the Tough Battle against Pollution in Provinces (Autonomous Regions and Municipalities directly under the Central Government), both have attached importance to the corporate responsibility.
2, Financial Support and Guidance
the Office of The State Council issued the Notice on the Reform Plan for the Division of Central and Local Financial Powers and Expenditure Responsibilities in the Field of Ecology and Environment. The Ministry of Ecology and Environment has also issued the Notice on Recommending Pilot Projects of Eco-environment-oriented Development Mode, and have been carrying out pilot projects, exploring the effective integration of eco-environmental governance projects with resources and industrial development projects.
In terms of taxation, pilot reform of water tax has been carried out, replacing fees with taxes. In addition, the establishment of the National Green Development Fund has given full play to the guiding role of government funds and the decisive role of the market in resource allocation.
3, Configuring and Optimizing Market Resources
To support the local establishment of river basin ecological compensation mechanism, the Treasury also led numbers of implementation plan in order to establish a reward incentive mechanism and to encourage basin-build mechanism between upstream and downstream.
In addition, the Ministry of Science and Technology and six other ministries jointly issued the Implementation Opinions on Creating a Better Development Environment to Support the Healthy Development of Private energy conservation and environmental protection enterprises, to maintain a market and business environment where private enterprises can compete fairly and private energy conservation and environmental protection enterprises can develop healthily.
4, supporting implementation
Measures have been taken in four aspects, namely, improvement of water environment, infrastructure construction, agricultural pollution sources, and urban areas pollution. Notices, guidelines and regulations are carried out in order to tackle the major difficulties in water control.
The environmental protection enterprises have gone through three stages:
1, the battle against the pandemic
China’s water treatment enterprises proactively fulfill their social responsibilities, make donations, and provide technical support for medical sewage treatment at the front line. They ensure the 100% coverage of national medical sewage and urban sewage supervision and control work and 100% rectification of problems detected.
2, the resumption of work and production
In this stage, the production and operation of environmental protection enterprises resumed in an orderly manner, tried to reduce operating costs, and actively carried out self-help, while the decline of enterprises’ revenues, due to the epidemic, was gradually reduced.
3, the battle against the water pollution
Since the end of the third season of 2020, environmental protection enterprises have entered the final stage of the battle against water pollution. The market demand for water environment has been continuously released in the short term and is gradually recovering and approaching the previous level.
Overall, the sewage control enterprises have improved in problem diagnosis, process design, technological equipment and system solutions’ quality, through shareholding, joint venture and multidisciplinary, multi-dimensional cooperation, the industry is entering a new stage of giant transverse joint.
Technological Hot Points
The main technological development of sewage treatment industry is embodied in the following two aspects:
1, Collaborative Treatment and Optimization of Conventional Pollutants
The focus is on the removal of nutrients such as nitrogen and phosphorus, the synergistic treatment effect can be improved through enrichment of dominant strains, improvement of fillers, and multi-field coupling optimization of different physicochemical and biochemical treatment units. Through accurate aeration of biological treatment unit, intelligent dosing and energy saving and consumption reduction, the management of the sewage plants can be improved.
2, In terms of efficient treatment of refractory pollutants
membrane – Fenton technology, radiation technology, electric field enhanced hydrolysis and acidification, ozone multi-phase catalytic oxidation, resin adsorption recovery and other technologies further improve the removal effect of refractory organic pollutants. The techniques of step salt extraction by evaporation crystallization, immersion combustion evaporation, multi-stage pyrolysis furnace and harrow furnace provide technical solutions for the treatment of reverse-osmosis concentrated water evaporation byproducts.
