Zusammenfassung: | PROBLEM TO BE SOLVED: To sufficiently mix sewage and a chemical soln. by opening the pipe end of a sewage pipe to a treatment tank on the downstream side thereof and connecting a chemical soln. pipe to a sewage pipe and forming a bent part on the downstream side of the connection place of the chemical soln. pipe to the sewage pipe. SOLUTION: The pipe end 13a of a sewage pipe 13 is opened to a treatment tank 2 on the downstream side in the tank and one or a plurality of chemical soln. pipes 14 are connected to the sewage pipe 13 and a bent part 13b is formed on the downstream side of the connection part 15 of the sewage pipe 13 and the chemical soln. pipes. The bent pipe 13b is bent at a right angle at one place or a plurality of places. By this constitution, the sewage passing through the sewage pipe 13 is mixed with the chemical soln. from the chemical soln. pipes 14 and the chemical soln. is uniformly mixed with sewage by the agitating action generated when sewage flows through the bent part 13b of the sewage pipe 13 to be allowed to flow into the treatment tank 2. As a sesult, the chemical soln. is uniformly mixed with sewage and reaction treatment is sufficiently performed and it can be prevented that sewage flows out of the treatment tank 2 in an untreated sewage state. |
