【Chemical Machinery and Equipment Network Policies and Regulations】Heavy metals refer to metals with a density of more than 5, such as gold, silver, copper, lead, zinc, nickel, cobalt, cadmium, chromium and mercury and other 45 kinds
.
Heavy metal pollution is mainly caused by human factors such as mining, exhaust emissions, sewage irrigation and the use of heavy metal products, mainly refers to mercury, cadmium, lead, chromium and metallometalloid arsenic and other biotoxic heavy metals, but also refers to general heavy metals with certain toxicity such as zinc, copper, cobalt, nickel, tin, etc
.

Heavy metal pollution has the characteristics of long-term, cumulative, latent and irreversible, and the treatment cost is high, the harm is large, and it will cause serious harm
to the environment and the human body itself.
For example, for the human body, mercury will sink directly into the liver after ingestion, which will cause great damage to the brain vision nerve; Chromium can cause numbness in the limbs, mental abnormalities, etc
.

At present, the main source of heavy metal pollution is industrial pollution, most of which are discharged into the environment through waste residue, waste water and waste gas; Followed by traffic pollution and household garbage pollution, traffic pollution such as automobile exhaust emissions, domestic pollution is mainly some domestic garbage pollution, such as waste batteries, residual cosmetics, glazed dishes, etc
.

According to the standard document "National Economic Industry Classification" issued by the National Bureau of Statistics, the heavy metal pollution prevention and control service industry belongs to the "environmental treatment industry (N772)" in the "ecological protection and environmental governance industry (N77)
".
In recent years, in order to prevent and control heavy metal pollution, the state has also introduced many relevant policies, and some of the relevant policies in the past two years are summarized as follows, welcome to add!

03 "Opinions on Further Strengthening the Prevention and Control of Heavy Metal Pollutants"

The "Prevention and Control Opinions" clearly states that during the "14th Five-Year Plan" period, the prevention and control of heavy metal pollution should grasp the general requirements of pollution reduction and carbon reduction, take improving the quality of the ecological environment as the core, effectively prevent and control heavy metal environmental risks as the goal, and take the emission reduction of key heavy metal pollutants as the starting point
。 By 2025, the emission of key heavy metal pollutants in key industries nationwide will be reduced by 5% compared with 2020, the green development level of key industries will be rapidly improved, the environmental management capacity of heavy metals will be further enhanced, and a number of prominent historical heavy metal pollution problems will be promoted; By 2035, establish and improve the heavy metal pollution prevention and control system and long-term mechanism, comprehensively improve the heavy metal pollution control capacity, environmental risk prevention and control ability and environmental supervision capacity, and comprehensively and effectively control
the environmental risk of heavy metal.

12 Implementation Plan for Industrial Wastewater Recycling

The "Plan" proposes to guide key enterprises, scientific research institutes, industry associations, etc.
to form industrial wastewater recycling industry alliances, focusing on water-scarce areas and water-sensitive areas, and providing integrated comprehensive services such as information consultation, technical transformation, facility construction, operation and maintenance for the wastewater recycling of key water-using enterprises through professional modes such as water-saving management and entrusted operation, and systematically improving the level of wastewater recycling of
enterprises.

2021.
03 Outline of the 14th Five-Year Plan for National Economic and Social Development and the Long-range Goals for 2035

The "Outline" puts forward that it is necessary to fight the battle of pollution prevention and control in depth, establish and improve the environmental governance system, promote precise, scientific, legal and systematic pollution control, coordinate to promote pollution reduction and carbon reduction, continuously improve the quality of air and water environment, and effectively control soil pollution risks: strictly prevent and control environmental risks, strengthen the monitoring and early warning of heavy metal pollution in key regions and key industries; Vigorously develop the green economy and promote service models such as third-party governance of environmental pollution; Build a resource recycling system, further promote the recycling transformation of the park, complete and extend the industrial chain, and promote the cascade utilization of energy resources, the recycling of hair and the centralized disposal
of pollutants.

2021.
01《Guiding Opinions on Promoting the Utilization of Sewage Resources》

The "Guiding Opinions" clearly states that by 2025, the efficiency of sewage collection nationwide will be significantly improved, the sewage treatment capacity of counties and cities will meet the needs of local economic and social development, and sewage treatment in water-sensitive areas will basically be upgraded and upgraded.
The utilization rate of reclaimed water in water-scarce cities at the prefecture level and above has reached more than
25%.
