分散式污水處理系統(tǒng)作為適用于低密度社區(qū)污水處理的解決方案已經(jīng)引入,而污水處理系統(tǒng)無法使用。農村地區(qū)的分散式污水處理系統(tǒng)對于防止水環(huán)境污染非常重要。日本的污水處理技術（Johkasou）已經(jīng)進行了研究,以評估中國餐飲廢水治理的可行性,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處理系統(tǒng)Johkasou對CODCr,NH3-N,TP和TN去除效率的評估,以評估中國餐飲廢水處理的可行性。本研究包括餐飲廢水的特點,系統(tǒng)的去除效率和處理系統(tǒng)在不同季節(jié)和時間內的機理,以確定時間變化。此外,處理系統(tǒng)由三個隔室組成,厭氧,需氧和消毒,具有不同的去除能力,以確定每個隔室的不同指數(shù)。在夏季,秋季,冬季和冬季期間,餐飲廢水中CODCr的進水濃度范圍為244 至 1035 mg/L,NH3-N 為 7.0 至 30.6 mg/L,TP 為 1.33 至 4.74 mg/L,TN為12.2至43.6 mg/L春季。該處理系統(tǒng)正在利用微生物的活性進行操作,以去除餐飲廢水中的這些指標,分別為CODCr56%,NH3-N12.3%,TP12.2%和TN11.6%的去除效率。這項研究顯示其三個指標的最高去除效...
