摘要
系統(tǒng)介紹了活性污泥膨脹的概念、類型和相關理論。從碳水化合物含量高的廢水、陳腐或腐化的廢水、含有毒物質的廢水、N、P含量不平衡的廢水、低PH值的廢水等方面論述進水水質對污泥膨脹的影響;從水流流態(tài)及運轉方式、流量和水質變化、其他環(huán)境因子(PH,溫度,營養(yǎng)成分)等環(huán)境條件論述其對污泥膨脹的影響;和從負荷、溶解氧、污泥齡等運轉條件來論述其對污泥膨脹的影響。提出了應急調控措施、環(huán)境調控措施和工藝運行調控措施來控制污泥膨脹。
Abstract
In this paper,the concept,types and mechanism of activated sludge bulking were introduced.The factors affecting the sludge bulking were discussed from the aspects of wastewater quality,such as wastewater with high content of carbon hydrate,decayed wastewater,wastewater with toxic substance,wastewater with unbalanced content of N and P and wastewater with low pH value;the environment conditions such as flowing state of the flow,operation manner,variation of water quality and other factors(pH,temperature,nutrition) etc.And also,the emergency controlling,environment controlling and process operating controlling methods are put forward for controlling activated sludge bulking.
