摘要:- 浙江某污水廠進(jìn)水中含有70%的工業(yè)廢水，具有有機(jī)物濃度高、沖擊負(fù)荷大、乳化油濃度較高的水質(zhì)特點(diǎn)，且出水水質(zhì)要達(dá)到《城鎮(zhèn)污水處理廠污染物排放標(biāo)準(zhǔn)》（GB 18918—2002）中一級(jí)A標(biāo)準(zhǔn)。已建一期工程(2×104 m3/d)采用AAO+高效沉淀池+濾布濾池工藝處理污水，出水有機(jī)物超標(biāo)嚴(yán)重。為此，二期擴(kuò)建工程(2×104 m3/d)采用調(diào)節(jié)池+混凝氣浮組合池+A/O生化池+高效沉淀池的工藝流程。設(shè)計(jì)中增設(shè)調(diào)節(jié)池調(diào)節(jié)進(jìn)水水質(zhì)水量；采用混凝氣浮組合池去除進(jìn)水中的乳化油，以避免對(duì)后續(xù)工藝運(yùn)行造成干擾；延長(zhǎng)生化池停留時(shí)間，強(qiáng)化對(duì)有機(jī)物的去除，避免在深度處理階段設(shè)置高級(jí)氧化工藝，節(jié)省建設(shè)、運(yùn)行費(fèi)用；氣浮污泥采用離心脫水，生物污泥采用帶式脫水機(jī)處理。工程試運(yùn)行期間出水水質(zhì)穩(wěn)定達(dá)到設(shè)計(jì)標(biāo)準(zhǔn)，直接運(yùn)行成本為0.56元/m3。
Abstract:- The influent of a wastewater treatment plant in Zhejiang Province contained 70% industrial wastewater with high concentration of organic matter and emulsified oil, as well as high impact load. However, the effluent should reach the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). AAO tank, high-efficiency sedimentation tank and cloth-media filter were used in the first-stage project(2×104 m3/d), which caused severe excess of effluent organic matter. Therefore, the regulating tank, coagulation/air floatation unit, A/O tank and high efficiency sedimentation tank were applied in the second-phase expansion project (2×104 m3/d). The design features were as follows: adjusting the quality and quantity of influent by adding a regulating tank; The coagulation/air floatation tank was used to remove the emulsified oil, so as to avoid the interference with the subsequent process operation; By extending the residence time of the biochemical tank, the removal of organic matter was strengthened, advanced oxidation process could be avoided in advanced treatment stage, which would save the costs of construction and operating. For air floatation sludge, centrifugal dewatering were selected, and belt filter dewatering were selected for the biochemical sludge. During the trial operation of the project, the effluent quality was stable and reached the design standard, and the direct operation cost was 0.56 yuan/m3.
