摘　　要：本文调查了７８处住宅净化沼气池和３０处标准化粪池，分析比较了２８处净化沼气池的设计参数。吸收部分厌氧处理新技术，并对装置结构和处理工艺作了调整和改进后，设计制作了模拟装置，分别作了处理粪污和生活污水的常温实验，出水水质达到《污水综合排放标准》二级标准和《粪便无害化卫生标准》要求。提出了以进水水质、水量、滞留期及人均池容等的综合设计参数和两种处理工艺，简化了容积计算公式，并经现场应用验证。biogas tanks and 30 standard septic tanks in urban residential districts,wereinvestigated.Analysis and compatison of design parameters were made among 28 biogas tanks.Afterparameter adjusting a simulated device bas been developed according to some new tecbnology andanalyzing results.Both manure and sewage were tested as sole meterlal in the simulated deviceundet ambient tempetature. In both cases,the quality of effluent meet the second class standatd of “Integrated Wastwater Discbarge Standard”.Influent quality and quantity,retention time andaverage design volume per person have been proposed as the comprehens ive des ign parameters. Two treating processes have been developed in our study.All these simplified the calcnlating formulafor design volume and were verified through field practice.The presenting study is practical andeasy to be expended in practice.
