The main measures to prevent water pollution are: (ABC)

A. reducing and eliminating emissions from pollution sources

B. Overall planning and rational layout

C. Strengthen inspection management and formulate regulations and control standards.

D, quickly wash away the pollutants leaked into the water body.

What are the prevention and control measures for water pollution?

1, the development and utilization of resources should adhere to the principle of both open source and throttling.

Vigorously carry out water-saving activities and take effective measures to reduce water consumption. Organize the implementation of water-saving and efficient agricultural irrigation technology; Improve scientific agricultural water management measures and change the situation of large water consumption in agricultural production as soon as possible.

Formulate water quota for unit products and assessment indicators for water reuse rate, and establish an assessment system for industrial water use; It is clearly stipulated that industrial wastewater such as cooling water and process water must be recycled; Vigorously develop the closed-circuit circulation of water to minimize wastewater discharge.

While saving water and solving the shortage of water resources in China, we should comprehensively strengthen the prevention and control of water pollution, especially in key river basins. The focus of river basin management is the treatment of urban industrial wastewater and domestic sewage. Centralized treatment should be combined with decentralized treatment, and sewage should be recycled.

Construction of sewage treatment facilities according to local conditions, the treated sewage should be used for industrial cooling water, urban landscape and garden green space water.

2 establish and improve the system of paid use of resources and the price system.

Relevant state departments should pay close attention to organizing and carrying out resource pricing research, formulate classified pricing policies for important resources related to the national economy and people's livelihood and national scarce resources in a planned way, and change the unreasonable situation that resource products are "valuable without market" and the prices are low as soon as possible.

Make the price of water resources reflect resource value, resource utilization rate and pollution prevention cost. At the same time, actively promote the process of capitalization management of water resources, strengthen the study of resource accounting system, and create conditions for gradually bringing water resources accounting into the national economic accounting system.

3. Improve environmental and economic policies.

Pay close attention to formulating environmental economic policies conducive to environmental protection and further strengthen environmental economic means under the market economy system. Raise the standard of sewage charges as soon as possible to make it higher than the cost of pollution control; Formulate policies related to water pollution prevention and control, and establish a compensation mechanism for resource renewal.

Fully realize the principle of "polluter pays", and generally increase the sewage treatment fee as the operating cost of urban sewage treatment plants in water charges; Environmental protection, as a "market failure" field, especially environmental science and technology research and development, environmental protection infrastructure construction and so on. The state should strengthen industrial policy support.

Actively establish an environmental tax system. Expand the scope of resource tax collection and levy resource tax on scarce resources such as groundwater; Levy adjustment tax on investment direction of fixed assets on newly-built pollution projects to control structural pollution.

Analyze the advantages and disadvantages of the current sewage charges and fees changing into taxes, and explore the collection of pollution surcharges; Implement zero tax rate for enterprises engaged in urban sewage treatment; Preferential tax relief shall be given to the production of renewable resources and products produced by using renewable resources.
