摘要
我国已经进入城镇化中后期,污水处理过程中产生的污泥已经成为制约整个污水处理行业健康发展的瓶颈问题。国际上目前采用的几种污泥处理处置方式中,污泥的土地利用比较适应中国国情,但目前污泥土地利用的技术还不成熟。本研究探讨了复合菌剂与辅料配比对污泥好氧发酵工艺的影响。不同菌剂和辅料配比的污泥发酵试验结果表明,添加了菌剂的堆体在发酵过程中堆体温度明显高于未添加菌剂的堆体,当污泥和辅料的质量比为3:1时堆体的温度能达到较高值。
Wastewater treatment is seriously restricted by sludge.Sludge application on land is the best way in China.But now,the techniques in sludge treatment are not yet refined.In this paper,the influence of compound microorganisms and the matching of accessories to fermentative treatment of sludge are studied.The results show that compound microorganisms significantly affect sludge fermentation.Temperature reaches higher value when the sludge and the mass ratio of the accessories is 3： 1.
