SEWAGE TREATMENT SYSTEM AND SEWAGE TREATMENT METHOD
PROBLEM TO BE SOLVED: To provide a sewage treatment system and a sewage treatment method producing a hypobromous acid compound at a stable concentration, capable of swiftly and efficiently utilizing the disinfection effect of a hypobromous acid compound and capable of swiftly dealing with large quantity of sewage treatment upon large quantity rain fall as well.SOLUTION: Provided is a sewage treatment system comprising: a treatment passage 10 where sewage flows in-out; a reaction flow passage 20 in which the downflow edge 20b is connected to the treatment flow passage 10; a hypobromous acid feed apparatus 30 connected to the upstream edge 20a of the reaction flow passage 20 and feeding the aqueous solution of a hypobromous acid; and a bromide feed apparatus 40 feeding the aqueous solution of a bromine compound. The reaction flow passage 20 is the one reacting the aqueous solution of a hypobromous acid compound fed from the hypobromous acid feed apparatus 30 and the aqueous solution of a bromine compound fed from the bromide feed apparatus 40 while circulating the inside of the flow passage without being contacted with the air to produce a hypobromous acid compound.SELECTED DRAWING: Figure 1
【課題】次亜臭素酸化合物を安定した濃度で生成させ、次亜臭素酸化合物の消毒効果を迅速かつ効率的に利用でき、大量降雨時における大量の下水処理にも迅速に対応できる下水処理システムおよび下水処理方法を提供する。【解決手段】下水が流入、流出する処理流路１０と、前記処理流路１０に下流端２０ｂが接続された反応流路２０と、前記反応流路２０の上流端２０ａに接続された、次亜塩素酸化合物の水溶液を供給する次亜塩素酸供給装置３０および臭素化合物の水溶液を供給する臭化物供給装置４０とを備え、前記反応流路２０は、前記次亜塩素酸供給装置３０から供給された次亜塩素酸化合物の水溶液と前記臭化物供給装置４０から供給された臭素化合物の水溶液とを流路内を空気に触れさせずに流通させながら反応させて次亜臭素酸化合物を生成せしめる流路である下水処理システム。【選択図】図１
