For production wastewater containing a class of pollutants specified by the state (mercury、chromium、lead、cadmium、arsenic、nickel、13 silver, etc.)，Must be collected separately，Handled separately，Separate discharge (installation of workshop discharge port)、Individually measured。
4. Normative monitoring、监测有效
企业要对自动监控设施运维和管理负主体责任，It is necessary to set up a monitoring station，Equipped with air conditioning、UPS、power supply and other facilities，The sampling pipeline should be open，Make sure the wastewater flow meter、On-line monitoring equipment、Automatic monitoring facilities such as IC card total equipment are operating normally，Unauthorized demolition is prohibited、Idle automatic monitoring facilities，It is forbidden to change the relevant parameters、data、procedure，or violation of technical specifications，Take a replacement、dilute、adsorption、absorb、Filtration and other methods are used to process and monitor samples。
Requirements for the management of air pollutant prevention and control facilities
1. Strengthen source control。
Avoid foul odors from production and use、Odorous products and substances。Phase-out produces foul odors、Odorous products、Processes and equipment。printing、furniture、Panel、Machinery and equipment、electron、Organic solvents are used for painting, etc、Industries or enterprises that emit volatile substances such as cleaning agents，Water-based alternative processes should be actively promoted，Control the generation of exhaust gas pollution at the source。
2. Pollution prevention and control facilities are complete and maintain normal operation。
in the storage and transportation of materials、handling、Feeding、transport、mix、react、Discharging、All aspects such as sub-packaging should be fully considered and the exhaust gas should be collected in an organized manner，To be able to "collect everything"，Minimise fugitive emissions。Production and service activities that produce waste gases containing volatile organic compounds，It should be carried out in a confined space or equipment，and install it in accordance with the regulations、Use of pollution control facilities。The collected exhaust gas must be treated at an exhaust gas treatment facility。Keep the facility up and running，Discharge up to standard：Liquid spray treatment，Adequate fluids must be ensured、The agent is added in time、MAKE SURE THAT THE PH VALUE OF THE SPRAY SOLUTION IS WITHIN THE NORMAL RANGE (THE PH OF THE SPRAY LIQUID OF ACIDIC EXHAUST GAS FACILITIES SHOULD BE ALKALINE，The pH of the spray liquid of alkaline waste gas facilities should generally be acidic)；Incineration facilities ensure that parameters such as incineration temperature are within the normal operating range；Activated carbon treated，Replace the activated carbon in a timely manner according to the regulations，Replacement records are complete，The replaced waste activated carbon should be treated as hazardous waste and managed to be strengthened：Standardize storage、And promptly entrust a qualified unit to carry out safe disposal。
There are exhaust gases generated，However, in the original EIA, there were no specific requirements for waste gas treatment facilities，It shall be in accordance with the corresponding requirements of Article 108 of the Air Law，Build your own waste gas treatment facilities，Report at the same time、Acceptance。
3. Prevent leaks，Monitoring is effective。
petrifaction、Enterprises with organic waste gases, such as chemical industry, must carry out leak detection and repair，Enterprises involved in the use or emission of toxic and harmful gases，It is recommended to install a gas leakage alarm device according to the requirements of the safety department，Prevent and control safety accidents caused by the environment。Continuous improvement，Reduction of fugitive emissions。
4. Discharge port specifications。
Waste gas treatment facility treatment process、The exhaust gas discharge cylinder shall meet the requirements of the standards stipulated in the environmental impact assessment and relevant laws and regulations，Hang or post a schematic diagram of the operation of the facility around the exhaust gas treatment facility，According to the requirements of the standardization of sewage outlets, implement the environmental protection graphic signs (including the name of the discharge outlet) that meet the requirements、numbering、Company name, etc.)。
5. Online monitoring。
