National Industrial Wastewater Discharge Standards, Industrial Wastewater Discharge Standards

It depends on what industries and regions, countries and regions have regulations for certain special industries.

However, there is a principle that local standards give priority to the implementation of national standards, and cross-industry comprehensive emission standards and industry-specific emission standards are not cross-implemented.

Like what. Guangdong Province: Electroplating Water Pollutant Discharge Standard (DB441597-2015).

Guangdong Province "Water Pollutant Discharge Limits" DB4426-2001

Beijing: Water pollutant discharge standard DB11 890-2012 for urban sewage treatment plants

Water Pollution Complex Discharge Standard DB11 307-2013

Fujian: DB35-1310-2013 Fujian Province Pulp and Paper Industry Water Pollutant Discharge Standard.

DB35 321-2001 Minjiang River Water Pollutant Discharge Control Standard.

DB35 529-2004 Jinjiang and Luoyang River basins water pollutant discharge control standard.

Liaoning: Comprehensive sewage discharge standard DB 21 1627-2008

Wait a minute. National Standards:

Comprehensive Sewage Discharge Standard (GB8978-1996) and Sinopec Industry COD Standard Value Modification Sheet.

Discharge Standard for Water Pollutants in the Sugar Industry (GB 21909-2008).

Water pollutant discharge standard for down industry (GB 21901-2008).

Pollutant emission standard for livestock and poultry breeding industry (GB 18596-2001).

Emission Standard for Water Pollutants in Extractive Pharmaceutical Industry (GB 21905-2008).

Discharge standards for water pollutants in the bioengineering pharmaceutical industry (GB 21907-2008), etc.

Industrial wastewater discharge standards include:

1. The National Standard of the People's Republic of China "Comprehensive Sewage Discharge Standard" and the local pollutant discharge standards issued by the Ministry of Environmental Protection of the People's Republic of China;

2. Local pollutant discharge standards are formulated according to the pollution discharge situation in different regions, and the specific emission standards are also different in different regions.

Conditions for industrial wastewater discharge include:

1. The wastewater discharge standards of different industries and enterprises need to be adjusted according to the actual situation;

2. The maximum allowable discharge degree of industrial "wastewater" discharged into the water body with small flow, poor dilution capacity and water for fishing and aquaculture must be strictly controlled;

3. Refers to the total export of factory wastewater.

Differences in industrial wastewater discharge include:

1. Comprehensively inspect and supervise the entire water purification process with reference to various important indicators and large standards to ensure that industrial sewage and domestic sewage are effectively treated, avoid poor water treatment effect, and improve the level of sewage treatment;

2. Set up multiple water treatment links according to the actual demand for water, including physical treatment, chemical treatment and biological treatment, etc., to effectively remove pollutants;

3. For the treatment of toxic wastewater containing non-biodegradable wastewater, it must be treated separately and cannot be discharged into the urban sewer, so as not to affect the effect of municipal sewage treatment;

4. Part of the wastewater can be simply treated and reused, or discharged into the sewage system;

5. Strictly control the discharge of wastewater and limit the discharge of wastewater pollutants to reduce pollution to the environment.

Legal basis]:

Article 21 of the Law of the People's Republic of China on the Prevention and Control of Water Pollution.

Enterprises, public institutions, and other producers and operators that directly or indirectly discharge industrial wastewater and medical sewage into water bodies, as well as other wastewater and sewage that can only be discharged in accordance with regulations, shall obtain a pollutant discharge permit; The operating units of centralized urban sewage treatment facilities shall also obtain a pollutant discharge permit.
