- 摘要:
- 以青岛市某新区农村生活污水治理为例，在雨污分流前提下，开展农村生活污水及污泥 “相邻联治、分类分治、资源利用、因地制宜”的系统化治理模式的探索研究；对入户收集技术，污水、污泥的转输方式，污水管渠、检查井型式及管材，污水处理站规模、进水水质、出水标准及相适宜处理工艺，尾水贮存回用与生态处理，以及污泥的资源化利用处置方式等关键技术进行比选研究；并进行工程应用示范验证。实践表明，所选用的污水治理模式和技术取得了较好的效果，可以为各种不同情况的农村生活污水治理提供借鉴与参考。
- Abstract:
- This work takes the rural domestic sewage treatment in a new area of Qingdao as the research object. Considering the rain and sewage diversion, the systematic treatment modes of “adjacent joint treatment, classified and divided treatment, resource utilization and local conditions” for rural domestic sewage and sludge was explored. In this work, the following key technologies are compared and studied: domestic sewage collection technology, sewage and sludge transfer mode, sewage pipelines and ditches, inspection wells and pipeline material, scale of sewage treatment station, influent quality, effluent standard, suitable treatment technology, storage, reuse and ecological treatment of tail water, and resource utilization and disposal mode of sludge. The demonstration and verification of engineering application for this work was carried out. The practice has shown the selected sewage treatment mode and technology have achieved good results, which can provide reference for rural domestic sewage treatment in different conditions.
