Methods of remediation and prevention of environmental pollution

The following is related to the water environmental pollution in environmental pollution.

What are the root causes of pollution in rivers and lakes? There are three main causes: exogenous pollution, endogenous pollution and loss of ecological functions of water bodies.

The first is exogenous pollution, mainly from industrial wastewater, domestic sewage and initial rainwater.

Wastewater discharged directly or secretly from factories and domestic sewage from cities are directly discharged into natural water bodies through pipe networks, or overflow into natural water bodies when sewage treatment plants are overloaded and their treatment capacity is insufficient, thereby destroying water quality and causing serious river and lake pollution. When it rains, the initial rainwater reaches the ground through the atmosphere, and when it washes the ground, it brings harmful substances such as road pollutants and heavy metals into the pipe network and discharges them into natural water bodies, further aggravating the pollution of rivers and lakes. The exogenous pollution composed of industrial wastewater, domestic sewage and initial rainwater is the root cause of water environmental pollution.

This is followed by endogenous pollution, mainly from river and lake sediment, decaying aquatic flora and fauna, and coastal garbage.

Sediment pollution is when the water body is polluted, some pollutants in the water are stored in the sediment through precipitation or particulate matter adsorption, and re-released under appropriate conditions, becoming a secondary pollution source. In addition, the decay and decomposition process of animals and plants in the water will have a certain impact on the water quality, which may cause hypoxia in the water body, which will lead to pollution. The entry of coastal garbage into water bodies will further increase pollution.

Finally, there is the loss of ecological functions of water bodies. When the exogenous pollution and endogenous pollution are too heavy, the ecological function of the water body is destroyed, the water ecological function is lost, the self-repair and regulation ability is reduced, and the pollution is aggravated, forming a vicious circle.

According to incomplete statistics, at present, more than 90% of the water bodies in cities across the country are polluted to varying degrees (data** in the "River and Lake Pollution Status and Treatment Countermeasures" released by the Water Facilities Management Institute of Zengcheng District, Guangzhou in January 2019). In addition to more scientific development of urban water environment governance, as a member of the earth, our future destiny is closely related to the development of the ecological environment, and we should treat the ecological environment like life, implement the most stringent ecological environmental protection system, and firmly follow the civilized development path of production development, affluent life and good ecology, so as to build a beautiful China, create a good production and living environment, ensure global ecological security, and provide a strong guarantee for the sustainable development of mankind in the future!

1. Reduce pollutant emissions.

2. Control emissions and make full use of atmospheric self-purification capacity.

3. Site selection, chimney design, urban and industrial zone planning, etc. should be reasonable, and should not be excessively concentrated in large emissions, and should not cause repeated superimposed pollution and form local serious pollution incidents.

4. Afforestation.

5. Take comprehensive measures to control agricultural pollution 6. Improve the level of harmlessness, reduction and resource treatment of garbage.

What is the specific content of the measures to prevent and control environmental pollution in <>, the following Zhongda Consulting will answer for you.

1) Properly dispose of the slurry water transported by the sediment brigade, and shall not be directly discharged into urban drainage facilities and rivers without treatment.

2) In addition to having a device that meets the requirements, it is not allowed to melt asphalt or incinerate linoleum and paint on site to remove other substances that will produce toxic and harmful smoke and odorous gases.

3) Use a sealed coil pipe or take other measures to deal with high-altitude exhaust gases, and it is strictly forbidden to throw them downward from a height.

4) Take effective measures to control dust in the construction process.

5) The toxic and harmful waste sanitation center at the construction site should be properly disposed of, and it is forbidden to use toxic and harmful waste as earthwork backfill.

6) Effective control measures shall be taken for construction machinery that produces noise and vibration to reduce noise disturbance and occupational hazards.

7) To transport bulk bodies, fluid building materials or garbage, etc., the carrier should be tight, the shipment should be appropriate, and the transportation should not be leaked and flying, polluting the city. Construction waste should be removed and unloaded at the local location.

8) Units that are limited by technology and conditions and cannot control the pollution of the environment within the specified range, shall be reported to the local people's construction administrative department and the environmental protection administrative department with the approval of the town and Sui department.

The measures for the control of environmental pollution are as follows:

1. Environmental pollution refers to the act of natural or man-made destruction, adding a certain substance to the environment and exceeding the self-purification ability of the environment.

2. Environmental protection measures refer to the preparation of detailed environmental protection plans for the construction area and living area before the start of the project, and formulate measures to prevent environmental pollution in the construction area according to the specific construction plan, so as to prevent environmental pollution and damage in the vicinity of the construction area caused by the construction of the project.

Hazards of environmental pollution:

Environmental pollution will cause direct damage and impact on the ecosystem, such as: desertification, deforestation, and will also cause indirect harm to human society, sometimes the harm of this indirect environmental effect is greater than the direct harm caused at that time, and it is more difficult to eliminate.

Environmental pollution problems have occurred to varying degrees in the world, and the aspects with global impact include atmospheric environmental pollution, marine pollution, and urban environmental problems. With the globalization of the economy and China, environmental pollution is increasingly showing a trend of international sales, and the transboundary transfer of hazardous wastes is a prominent manifestation in this regard.
