1, the competent department of environmental protection of the people's government at or above the county level shall, in accordance with the authority, order it to be treated within a time limit and impose a fine of more than two times and less than five times the amount of sewage charges payable;

2. During the period of treatment within a time limit, the competent department of environmental protection shall order it to limit production, discharge or suspend production for rectification. The longest governance period shall not exceed one year;

3, overdue completion of governance tasks, with the approval of the people's government with the right to approve, shall be ordered to close down.

Environmental protection sewage detection standards are as follows:

1, Class A standard. When the effluent from urban sewage treatment plants is discharged into key river basins and closed or semi-closed waters such as lakes and reservoirs determined by the state and province, Class A standard shall be implemented;

2. When discharged into Class III functional waters of GB3838 Surface Water and Class II functional waters of GB3097 Seawater, the B standard in Class I standard shall be implemented;

3, secondary standards, urban sewage treatment plant effluent discharged into GB 3838 surface water five functional waters or GB 3097 seawater four functional waters, the implementation of secondary standards;

4. Class III standard. Urban sewage treatment plants in non-key control river basins and non-water source protection areas shall implement the third-level standards when adopting the first-level enhanced treatment process according to local economic conditions and water pollution control requirements. However, the location of secondary treatment facilities must be reserved to reach the secondary standard by stages.

Sewage is polluted water discharged in life and production. Water that loses its original function is called sewage for short. Mainly used water in life, which contains more organic matter and is easy to handle.

According to the viewpoint of sewage source, sewage can be defined as liquid or water with waste and mixed with groundwater, surface water and snow disaster discharged from houses, institutions, businesses or industrial areas. There are many kinds of sewage, and there are also many technologies and processes to reduce the impact of sewage on the environment.

According to the source of sewage, sewage can be divided into these four categories:

1. Industrial wastewater comes from sewage generated by mining and industrial production activities, including runoff leachate generated by industrial or commercial storage and processing, and other wastewater that does not belong to domestic sewage;

2. Domestic sewage comes from houses, office buildings, institutions or similar sewage; Domestic sewage; Sewer sewage, including industrial wastewater mixed with domestic sewage in the sewer system. The settlement of garbage and various atmospheric particles enters the water environment through surface runoff, soil erosion and farmland drainage. It has the characteristics of dispersion, concealment, randomness, latency, accumulation and fuzziness, and it is difficult to monitor and quantify, and it is also difficult to study and prevent. Substances that cause pollution when water pollutants are discharged into water bodies;

3. Commercial sewage is non-toxic and harmless sewage, which comes from commercial facilities and some components exceed domestic sewage. Such as restaurant sewage. Laundry sewage, animal feeding sewage, hair salon sewage, etc. ;

4. Surface runoff comes from rainwater, snow water, sewage in expressway, water in cities and industrial areas, etc. Surface runoff does not penetrate into soil, but enters groundwater along streets and land.

To sum up, among the water pollution caused by human production activities, industrial water pollution is the most serious. Such as industrial wastewater, which has many pollutants and complex components, is not only difficult to purify in water, but also difficult to treat. Industrial wastewater is the main cause of water pollution caused by industrial pollution. It accounts for most of the pollutants discharged by industry. Due to different types of factories, the pollutants contained in industrial wastewater vary widely. Even in similar factories, the quality and quantity of pollutants are different due to different production processes. In addition to the direct injection of industrial wastewater into the water body, solid waste and waste gas will also pollute the water body.

Legal basis:
