【摘要】：長治市位于山西省東南部,辛安泉是城市的唯一供水水源。辛安泉水通過兩條輸水管道輸送至第二水廠,管道輸送能力為17.28萬m3/d。水源一旦出現(xiàn)重大事件,長治市市區(qū)馬上會(huì)無水可用,將會(huì)嚴(yán)重影響長治市人民群眾正常生活和經(jīng)濟(jì)發(fā)展,進(jìn)而影響到城市的長治久安。目前,第一水廠日供水規(guī)模7萬m3,原為漳澤水庫的配套水廠。但是,水庫已停用多年,所以第一水廠也長期停產(chǎn)擱置,停用了近20年,設(shè)備嚴(yán)重老化,工藝落后,已經(jīng)不能滿足現(xiàn)有《生活飲用水衛(wèi)生標(biāo)準(zhǔn)》(GB5749-2006)的要求。所以必須將第一水廠改造,在原址建設(shè)7.5萬m3/d的水處理設(shè)施。第一水廠改建工程廠址選在現(xiàn)狀一水廠院內(nèi),將原有設(shè)施拆除,形成改建工程的用地。新建建、構(gòu)筑物包括綜合凈化間、清水池、送水泵房及變配電間、加藥消毒間、排水池、排泥池、污泥濃縮脫水車間、綜合樓等,總用地面積20067m2,總建筑面積14134.8m2。為了響應(yīng)國家節(jié)能減排號的召,選擇了污泥處理系統(tǒng)。本水廠經(jīng)處理后的出水水質(zhì)達(dá)到《生活飲用水衛(wèi)生標(biāo)準(zhǔn)》(GB5749-2006)的要求。采用“氣浮池+V型濾池”為主體的給水處理工藝以及“重力濃縮+離心脫水”為主體的污泥處理工藝。
[Abstract]:Changzhi City is located in the southeast of Shanxi Province, Xin'an Quan is the city's only water source. Xin'an springs are transported through two pipelines to the second water plant, with a capacity of 172800 m3 / d. Once there is an important event in the water source, there will be no water available in Changzhi city immediately, which will seriously affect the normal life and economic development of the people of Changzhi city, and then affect the long-term stability of the city. At present, the first water plant daily water supply scale 70, 000 m3, the original Zhangze Reservoir supporting water plant. However, the reservoir has been out of service for many years, so the first water plant has been suspended for a long time, which has been suspended for nearly 20 years. The equipment is seriously aged and the process is backward, which can no longer meet the requirements of the existing Sanitary Standards for drinking Water (GB5749-2006). So we have to rebuild the first water plant and build 75000 m3 / d water treatment facilities at the original site. The site of the first water plant reconstruction project is selected in the present water plant yard to demolish the original facilities and form the land for the reconstruction project. The new construction includes comprehensive purification room, clear water tank, water supply pump room and transformer and distribution room, medicament disinfection room, drain pool, mud drain pool, sludge concentration and dewatering workshop, comprehensive building, etc. The total land area is 20067 m2 and the total building area is 14134.8 m2. In order to respond to the call of national energy saving and emission reduction, sludge treatment system was selected. After treatment, the effluent quality of this water plant is up to the requirement of Sanitary Standard of drinking Water (GB5749-2006). The feed water treatment process with "V type air flotation filter" as the main body and the sludge treatment process with "gravity concentration centrifugal dehydration" as the main body were adopted.
