The protection of the environment is being valued by more and more countries and people. In the planning and design of environmental protection, we should combine the production point of view with ecological concepts and environmental protection, and seek a more reasonable management plan through systematic analysis and verification.

The main principles of environmental protection management can be summarized as follows:

(1) Eliminate unreasonable products in production;

For some traditional products with low output value and great difficulty in wastewater treatment, they can be replaced with products with high output value and high technology content. If the profit of a certain product is not comparable to the cost of wastewater treatment, is it worth continuing to produce?

(2) Strengthen management and reduce pollution;

Enterprise management is also an important factor in preventing and controlling pollution. The production of enterprises is often accompanied by the generation of many wastewaters. If the wastewater that does not meet the standards is discharged, it will cause some damage to the ecological environment. Therefore, enterprises are extremely important for the management of sewage.

(3) Establish regional small sewage treatment plants;

Where the factories are relatively concentrated, it is not necessary to implement sewage treatment in accordance with the principle of "who pollutes, who governs", but the relationship between enterprises should be strengthened, and pollution control measures should be considered as a whole. If necessary and possible, the wastewater of each factory can be treated in a centralized manner, and a unified sewage treatment plant can be established to implement the "who pollutes, who pays" treatment method.

Due to the different products produced by various factories, the quality of the wastewater produced is also different. It is quite difficult to treat all kinds of harmful substances separately, but if the wastewater of various factories is treated in a unified manner, not only can the difficulty of wastewater treatment be reduced, but also the efficiency of treatment can be improved.

(4) Improve the recycling rate of water;

In many countries, the recycling rate of water can be very high, and there are still many potentials for water utilization in many places waiting for people to tap. Increasing the recycling rate of production water can not only reduce environmental pollution, but also reduce the consumption of fresh water. To a large extent, this can alleviate the increasingly tense water resources problem.

(5) Recycling and comprehensive utilization of pollutants;

The pollutants in the wastewater are all produced during the production process, and the separation process of various substances cannot be very thorough, so the wastewater usually also contains a certain amount of useful substances.

If these substances are discharged, they will pollute the environment and cause harm to the ecology. But if it is recycled or comprehensively used, it can turn waste into treasure and turn harm into profit. Thinking from another point of view, waste can be treated with waste, and the strengths can be compensated for, so that the cost of water treatment can be saved.
