Please tell us about the sewage discharge standards of our company (region)
Thread Content
Nowadays, there is a huge gap in sewage discharge standards in many regions. The general rule is that economically developed regions have stricter implementation standards. Please tell us! ! ! In addition, I am from Hebei. Has anyone heard about the standard adjustment in Hebei Province? ! !
Here in Zibo, Shandong, we implement the first-level emission standards
Any emission standards are divided into* * Standards formulated and standards set by local governments (many places have not formulated standards and all adopt national standards), but the standards set by local governments must not be lower than * * requirements of established emission standards. It seems that there is no big difference in emission standards as mentioned by the original poster. There are also industry standards. The emission standards of various industries are somewhat different.
Yes, the emission standards of various industries are somewhat different. I agree with this. The paper industry, meat, printing and dyeing, steel, chemical, medical and other industries all implement different emission standards. Our factory in Jincheng, Shanxi Province, has an annual output of 360,000 tons of synthetic ammonia. I checked the relevant information and found that an enterprise with an annual output of more than 300,000 tons of synthetic ammonia is considered a large enterprise, so it should implement the corresponding emission standards, specifically as follows: Ammonia nitrogen is less than or equal to 60mg/l, COD is less than or equal to 150mg/l, SS is less than or equal to 70mg/l, PH 6 to 9. But the standard we have established now is ammonia nitrogen less than or equal to 70mg/l, COD is less than or equal to 150mg/l, PH 6 to 9.
Hunan has long implemented the first-level standard, and pure domestic wastewater generally implements the third-level standard.
The drainage outside the coking plant of our factory implements the first-level indicator. The water indicators sent to the environmental protection workshop are pH 6~9, ammonia nitrogen 300 and phenol 300.
Our company is located in Hebei and currently implements GB Level 2 standards.
We are located in the upper reaches of the Yangtze River, so the sewage is treated according to the* * The most stringent discharge standard, such as urban sewage treatment must reach the first-class A standard, industrial wastewater must reach the first-class standard after treatment, and even the first-class B standard for urban sewage discharge.
I am from Huaian. The water quality acceptance standards are the "Water Quality Standard for Sewage Discharge into Urban Sewers" CJ3082-1999 and the "Comprehensive Sewage Discharge Standard" GB8978-1996 Class II Pollutant Secondary Discharge Standard.
I am from Wuxi, Jiangsu Province. At present, most of the wastewater from Wuxi industrial enterprises is taken over from sewage treatment plants. The takeover standards mainly comply with the "Comprehensive Wastewater Discharge Standard" GB8978-1996 Class II Pollutant Level Three Discharge Standard. Among them, ammonia nitrogen and total phosphorus comply with the "Water Quality Standard for Sewage Discharge into Urban Sewers" CJ3082-1999.
Friends upstairs, how do you understand the takeover? Is the company's sewage directly discharged downstream without treatment? ? ? It shouldn’t be possible, but it should still be understood that the company’s sewage is discharged into the downstream municipal sewage treatment plant after treatment.
