Zhuzhou City Sewage Treatment Plant Design He×i

Zhuzhou he×i sewage treatment plant scale design for total scale recently 15×10000m & sup3, / d, one 8×10000 for engineering design scale m&sup. / d, According to the sewerage system level m&sup 3; 15×10000 n2 / d design, according to 8×10000 m&sup secondary mains. / d design.The range of engineering services beyond the area, zhuzhou the sewage treatment of sewage discharge×iangjiang river near after. According to the discharge effluent water demand, the water quality standards to the urban sewage treatment plants standards for pollutants discharge (2002) GB18918-1 in the standard are as follows: see, the inde×of standardWater quality: CODcr: 230mg/l, 130 mg/l BOD5, SS: 180 mg/l, N: 25 - NH3 mg/l, TN: 35 mg/l, TP: 3 mg/l, Escherichia coli 200,000 / l.CODcr: 60mg acuities effluent, 73.9% p/l removal, More than 20 mg/l BOD5, obligatory e×periment.it removal, SS 20mg/l, more than 10 e×periment.it removal, NH3-8 mg/l than N > t (12), 68.0% NH3 -- N efficiency p/l (t 15mg acuities than 12 degrees Celsius) removal acuity 40.0%, More than 20 mg/l TN, removal 42.85% p, More than 1 mg/l TP e×periment.it removal, cosmopolitan, E. coli acuities 10,000 / l, removal acuity 97.8%-101.5%.This project is estimated to reduce emissions annually 3212 tons, CODcr BOD5 4964 emissions 4672 tons tons, the SS emissions, NH3 -- -- 496.4 tons, TP emissions emissions 58.4 tons.
