ABSTRACT Currently,the rainoverfallofthethirty—-sevenmunicipal pump stationsalong Suzhou Creek isthekey issue toimprove andstabilize theSuzhou Creek water quality。Based on thereview andanalysis ofthemeasurements ofreducing theoverfallofmunicipal pump stations,the overfall characteristics ofthemunicipal pump stations along Suzhou Creek are studied systematically and thoroughly,and the scientificand feasibleengineering measurements also are put forward inthispaper. Themain conclusions include asfollows. ofpollutants controlinsewerage are put forward forthefirst time in our country,and the necessary and feasibility ofreducing theoverall of municipal pump stationsalong Suzhou Creek byusingengineering measurements are pointed out. theoverfall’S causes and dataoftheoverfallofmunicipal pump stationsalong Suzhou Creek isanalyzed accurately,and characteristics ofthe larger overfall—amount pump stations,the overfall’Sformations,the overfall’S water qualityand itsinfluence on Suzhou Creek are larger overfall—amount pump stationsand rainoverfalI are thekey adverse factorsofSuzhou Creek water quality. thebaseofoverfall' scientific and feasibleengineering measurements are proposed,including constructing thechiefinterception pipealong thesouth bank,constructing therainstorage tank,dredging thesewage pipe under Suzhou Creek,eliminating the pipe leakage,rebuilding the operation—test pump stationsand perfecting the are very important forreducing the overfallamount and pollutant loads effectively toprotect theSuzhou Creek water quality. 4Thc effectof fiverain tanks are thereduced overfallamount. thereduced pollutant amount ofCODen and theincreased concentration value of CODcr inSuzhou resultsshow thatthefiverainstorage tanks are very important forimproving theSuzhou Creek waterquality furthermore. proposed engineering measurements could eliminate theoverfalls in
