摘要
系統(tǒng)介紹了活性污泥膨脹的概念、類型和相關(guān)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(zhì)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(jìn)水水質(zhì)對(duì)污泥膨脹的影響;從水流流態(tài)及運(yùn)轉(zhuǎn)方式、流量和水質(zhì)變化、其他環(huán)境因子（PH,溫度,營(yíng)養(yǎng)成分）等環(huán)境條件論述其對(duì)污泥膨脹的影響;和從負(fù)荷、溶解氧、污泥齡等運(yùn)轉(zhuǎn)條件來(lái)論述其對(duì)污泥膨脹的影響。提出了應(yīng)急調(diào)控措施、環(huán)境調(diào)控措施和工藝運(yùn)行調(diào)控措施來(lái)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.
