2, sewage information
wastewater
Wastewater discharge standards: "Water Quality Standards for Wastewater Discharge into Urban Sewers"
Number of wastewater discharge outlets: 1
Total approved wastewater discharge: 2697t/a
Wastewater discharge form: The existing project process wastewater pretreatment will take over the Shaobo Town Sewage Treatment Plant after the pretreatment at the sewage treatment station reaches the standard.
Actual discharge concentration of wastewater: COD: 23.4mg/L, PH value: 7.0mg/L, SS: 5.50mg/L, ammonia nitrogen: 0.096mg/L, total phosphorus: 0.14mg/L, total nitrogen: 1.265mg/L.

exhaust gas
Exhaust gas emission standards: "Comprehensive Emission Standards for Air Pollutants" (GB16297-1996)
Number of exhaust gas outlets: 6
Total approved exhaust gas emissions: SO2:0.967,NOX:4.12, particulate matter: 0.528, VOCS:0.13.
Exhaust gas emission form: The company's boiler exhaust gas is now treated with a multi-tube cyclone dust collector + water film dust removal alkali spray system. After treatment, the flue gas is discharged through a 15m high exhaust pipe.
Actual emission concentration of exhaust gas: particulate matter: 5.63mg/m3,VOCS:10.04mg/m3, Smoke: 9.23mg/m3,Sulfur dioxide: 116.5mg/m3, Nitrogen oxides: 87.5mg/m3.

3, pollution prevention measures
Brief introduction to the operation of pollution prevention measures and whether they are operating normally.
Wastewater: The existing project has built three sets of sewage collection systems, including rainwater collection pipe network, process wastewater collection pipe network and domestic sewage collection pipe network.The rainwater collection ditches are all anti-seepage and covered with covers; the rainwater collection system is equipped with a switching device. After the rainwater collection system completes the initial collection of rainwater, it switches clean rainwater to the rainwater discharge pipe.
Exhaust gas:The enterprise collects and processes the organic waste gas generated in each workshop. The specific measures are: the enterprise plans to directly set up connecting air ducts at the equipment that generates organic waste gas to collect the organic waste gas generated by volatilization, so as to reduce the unorganized emission of organic waste gas. The organic waste gas collected in the workshop The exhaust gas is led from the air duct to the high-efficiency activated carbon adsorption device on the roof of the workshop, and after it reaches the standard, it is discharged from the 15m-high exhaust pipe.The absorption and purification efficiency of the high-efficiency activated carbon adsorption tower is >90%. After treatment, the waste gas can meet the requirements of corresponding pollutant emission standards and will not have a significant impact on the interior of the project and the surrounding atmospheric environment.Therefore, the measures currently taken by the project to prevent and control organic waste gas pollution are effective.
