摘要
利用研制的60L/h污水的渠式动态模拟装置,研究城市污水的渠内处理技术。结果表明,此法比传统的城市污水处理方法能提高COD_(Cr)的脱除率约4％～5％,而工程建设费和运行管理费分别降低30％～40％和25％～30％。渠内处理适宜与自然净化结合进行,出水经植物净化12～15h后,BOD_5进一步降低18％以上。由此可见,城市污水渠内处理技术具有良好的应用前景。
The technique of treating municipal sewage in a strip dynamic simulating reactor which could treat 60L/h sewage has been studied. The results showed that CODCr and BOD5 removing efficiencies of this technique were 4 ~ 5% higher than those of traditional techniques; the construction investement and operation expenses could be reduced by 30% - 40% and 25% - 30% respectively; 'Plant treatment' could be easily combined with this technique, 18% of BOD5 could be further removed after plant puification was applied. From these results, we could draw a conclusion that this technique not only disposed municipal sewage, but also beautified the surrounding environment of sewage canal, thus, this technique has bright application prospect.
