Application of Treatment Plant Johkasou on Restaurant Wastew

发布时间：2021-08-10 13:09

　　分散式污水处理系统作为适用于低密度社区污水处理的解决方案已经引入,而污水处理系统无法使用。农村地区的分散式污水处理系统对于防止水环境污染非常重要。日本的污水处理技术（Johkasou）已经进行了研究,以评估中国餐饮废水治理的可行性,并且其去除效率符合污水排放指南。本研究基于低成本分散式处理系统Johkasou对CODCr,NH3-N,TP和TN去除效率的评估,以评估中国餐饮废水处理的可行性。本研究包括餐饮废水的特点,系统的去除效率和处理系统在不同季节和时间内的机理,以确定时间变化。此外,处理系统由三个隔室组成,厌氧,需氧和消毒,具有不同的去除能力,以确定每个隔室的不同指数。在夏季,秋季,冬季和冬季期间,餐饮废水中CODCr的进水浓度范围为244 至 1035 mg/L,NH3-N 为 7.0 至 30.6 mg/L,TP 为 1.33 至 4.74 mg/L,TN为12.2至43.6 mg/L春季。该处理系统正在利用微生物的活性进行操作,以去除餐饮废水中的这些指标,分别为CODCr56%,NH3-N12.3%,TP12.2%和TN11.6%的去除效率。这项研究显示其三个指标的最高去除效...
