- 摘要:
- 綜合考慮污水廠(chǎng)擴(kuò)容、管網(wǎng)擴(kuò)建及河道生態(tài)補(bǔ)給，采用分散型污水處理理念，將城市污水泵站改造為河道生態(tài)補(bǔ)給站，就地處理就近補(bǔ)給河道。生態(tài)補(bǔ)給站設(shè)計(jì)規(guī)模為6 000 m3/d，采用集約化、地埋式設(shè)計(jì)，選用A2O+MBBR、矩形沉淀池、混凝沉淀池、轉(zhuǎn)盤(pán)濾池、活性炭過(guò)濾等先進(jìn)工藝，實(shí)際出水COD、BOD5、SS、氨氮、TN、TP均值分別為20.5、3.95、5.7、0.46、12.1、0.16 mg/L，各指標(biāo)達(dá)到準(zhǔn)地表Ⅳ類(lèi)標(biāo)準(zhǔn)。本項(xiàng)目的實(shí)施為城市中心區(qū)污水處理設(shè)施建設(shè)及區(qū)域水環(huán)境綜合治理提供了新思路和設(shè)計(jì)借鑒。
Abstract:- Considering the expansion of the wastewater treatment plant, extension of the pipeline network and ecological replenishment of the river, the concept of decentralized sewage treatment was adopted. A river ecological replenishment station (RERS) was established in the middle section of the main pipeline of the city so that its effluent could be used for river replenishing nearby. Based on the concepts of intensiveness and buried design, the process including A2O and MBBR, rectangular settling tanks, coagulation settlement tank, rotary filter and active carbon filtration was selected, with the design capacity of 6 000 m3/d. The average effluent COD, BOD5, SS, NH3-N, TN, TP were 20.5 mg/L, 3.95 mg/L, 5.7 mg/L, 0.46 mg/L, 12.1 mg/L, 0.16 mg/L, respectively, which could basically meet level Ⅳ of Environmental Quality Standards for Surface Water(GB 3838-2002). The implementation of this project provides a new idea and design reference for the construction of urban wastewater treatment facilities and comprehensive treatment of regional water environment.
