摘要
Abstract
Conventional activated sludge treatment cost a lot,and would cause secondary pollution if mismanaged.Sludge reduction by predation of tiny creatures was clean and not contsminative,so it was a green technology to control the source of sludge.The tubificidae in-situ sludge digestion technology was used to digest the sludge in adjusting tank of the Phoenix River 2nd-Ditch WWTP in Chengdu.Analyze the sludge reduction efficiency and water quality by monitoring experiments.The results indicate that the sludge reduction efficiency is conspicuous with sludge digestion 252.5t per year,the sludge settle ability is improved,and MLVSS/MLSS ratio decreased to 35.3％.Moreover,the COD removal rate of effluent is 30％ under normal circumstances,reduced the load for the follow-up process.关键词
