摘　　要：随着城市生活小区污水排放量的增加,产生的剩余污泥量也在增多,用于剩余污泥处理的投资和运行费用占总投资和总运行费用的比例较高,给生活小区污水处理应用带来一些困难.采用无剩余污泥水解酸化法处理生活小区污水,将中温厌氧酸化器和好氧生化系统组成一个循环系统,剩余污泥经过厌氧-好氧不断变化的历程,好氧微生物和厌氧微生物不断死亡并被降解.试验证明,反应器内温度控制在34℃,水力停留时间为1.5 d,pH在5.5～6.0对酸化反应器运行有利,可以减少或不排放剩余污泥量.With the increasing of the housing estate sewage the same time. The proportion that investment and operation quantity, residual sludge quantity is increasing at cost used for treatment of residual sludge is higher in total investment and operation cost, which brings some difficulties in the treatment of housing estate sewage. the non-residual sludge hydrolytic acidification process is taken to treat housing estate sewage. This cycle system is composed of medium-temperature anaerobic acidification reactor and aerobic biosystem. Aerobic and anaerobic microorganism die and are degraded continuously through a variable anaerobic-aerobic process. The test shows that the operation of acidification reactor has better effect under the condition of temperature 34 ℃, HRT 1.5 day, pH 5.5-6. 0. Residual sludge can be decreased or zero emitted.
