  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(wú)法使用。農(nóng)村地區(qū)的分散式污水處理系統(tǒng)對(duì)于防止水環(huán)境污染非常重要。日本的污水處理技術(shù)(Johkasou)已經(jīng)進(jìn)行了研究,以評(píng)估中國(guó)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(duì)CODCr,NH3-N,TP和TN去除效率的評(píng)估,以評(píng)估中國(guó)餐飲廢水處理的可行性。本研究包括餐飲廢水的特點(diǎn),系統(tǒng)的去除效率和處理系統(tǒng)在不同季節(jié)和時(shí)間內(nèi)的機(jī)理,以確定時(shí)間變化。此外,處理系統(tǒng)由三個(gè)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(gè)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(jìn)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(jìn)行操作,以去除餐飲廢水中的這些指標(biāo),分別為CODCr56%,NH3-N12.3%,TP12.2%和TN11.6%的去除效率。這項(xiàng)研究顯示其三個(gè)指標(biāo)的最高去除效...
