- 摘要:
- 某鎮(zhèn)紡織企業(yè)中水回用工程服務(wù)于7家噴水織機(jī)企業(yè)，設(shè)計(jì)處理規(guī)模6 500 m3/d，采用格柵+混凝氣浮+曝氣生物濾池處理工藝，通過20%中水與污水廠的尾水交換、含油污泥離心脫水將油類留存于泥餅的方式，消除中水回用的污染物循環(huán)富集問題。實(shí)踐證明，噴水織機(jī)廢水經(jīng)該工藝處理后，中水水質(zhì)達(dá)到了噴水織機(jī)用水要求，大大減輕了原集中處理污水廠的水處理負(fù)荷，使污水處理廠出水水質(zhì)穩(wěn)定達(dá)到《城鎮(zhèn)污水處理廠污染物排放標(biāo)準(zhǔn)》（GB 18918—2002）的一級(jí)A標(biāo)準(zhǔn)。
- Abstract:
- A reclaimed water reuse project with designed treatment capacity of 6 500 m3/d, which serves seven water-jet loom enterprises in a county, adopts the process of screen, coagulation flotation, and biological aerated filter. Twenty percent of the reclaimed water is exchanged with the effluent of the wastewater treatment plant(WWTP), and the oily sludge is centrifugally dehydrated to eliminate pollutant enrichment during reclaimed water cycling. Practice has proved that the quality of reclaimed water treated by this process can meet the demand of water-jet loom, which greatly reduces the water treatment load of the original centralized WWTP. Thereby the effluent of the WWTP reaches the discharge requirement of first level A criteria in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002).
