活性污泥法曝气池池容的理论推导

根据微生物反应动力学模型,推导了活性污泥系统中完全混合式与推流式曝气池池容的计算公式,并比较了在不同底物去除率下,两种池型容积大小。

Study on River Regulation in Urban Districts of Ningbo City

To guarantee water quality of waterscapes in Metal Park of Zhenhai District of Ningbo City, and keep it above the Grade-IV specified in Quality Standard of National Surface Water Environment (GB3838-2002), maintain low maintenance cost and long-term sustainable development of water, basic principles of ecological engineering and aquatic ecosystem balance theory were applied to instruct water treatment in the park. Micro-nano bubble gas-liquid dispersion and plugflow aeration were used to improve water quality.

针织印染废水的C-HC-PBCO-C处理工艺

采用混凝+水解酸化+推流式接触氧化+混凝(C-HC-PBCO-C)处理针织印染废水,结果表明,此工艺能有效去除废水中污染物,出水平均CODCr、BOD5、SS和色度分别为77 mg/L、13 mg/L、35 mg/L和30倍,出水水质达到广东省DB44/26—2001《水污染排放限值》第Ⅱ时段一级排放标准。

煤成气井固井工艺实践和认识

近５年来，淮南、安阳、柳林等地区１２口煤成气井采用塞流固井技术和漂珠低密度水泥浆固井技术取得成功，固并质量合格率为１００％，优质率为７８％。探讨了塞流固井中水泥浆动塑比的设计问题，给出了五种低密度水泥浆配方。
