深度处理生活污水以供采暖锅炉回用

针对我国水资源缺乏，作者设想“生活污水深度处理后供采暖锅炉回用”，并结合现场实际成功地进行了探索性试验─—用“缺氧水解－好氧处理”工艺深度处理生活污水。详述了工艺过程的机理及优于传统的活性污泥法之处。强调了深度处理工艺中的几个关键所在，如：好氧接触氧化法、Ａ／Ｏ生物处理系统的技术要点、氮氯基本原理及其特点等。该技术在温度较低的北方也有实用价值。生产性试验表明，应注意的问题是：冬季应采取保温措施；好氧混合液的回流量控制；水解池的使用潜力等。在辽宁盘锦地区采用的缺氧水解－好氧工艺生物处理法处理城市低浓度有机废水的生产性试验表明，它可为高效、低能耗、低成本处理城市污水提供新的途径。

Depth Treatment of Sanitary Sewage for eating Boiler Recycle

In view of the shortage of water resources in China,the writer con-ceived an idea of“depth treatment of sanitary sewage used for heating boiler recycle”andin combination with on the spot practice has successfully carried out exploratory test-depth treatment of sanitary sewage using“anaerobic hydrolysis-aerobic treatment ”tech-nology. This paper explains in detail the processing mechanism and its strong points se-nior to those of traditional activated sludge process.It stresses cruxes of depth treatmenttechnology,such as aerobic contact oxidation method,technical essentials of A/O biolog-ical treatment system,basic principle of denitrogenation and its characteristics. The saidtechnology is of practical value even in northern region having low temperature. Theproductive test shows the problems needing attention, heat prevention measures to betaken in winter,reflux control of aerobic mixed liquor , use potentiality of hydrolytictank ,etc.In Panjin area,Liaoning Province,the productive test adopting anaerobic hy-drolysis-aerobic biological treatment to deal with urban low concentration organic sewage indicates it is a new way to treat urban sewage with high efficiency ,low energy consumption and cost.
