Method and apparatus for sewage treatment by utilizing empty can
专利汇可以提供Method and apparatus for sewage treatment by utilizing empty can专利检索，专利查询，专利分析的服务。并且PURPOSE: To perform a high-degree sewage treatment without requiring any tertiary treatment, by a method wherein empty cans with microorganisms adhered to the inside and outside surfaces thereof are packed in a cleaning tank to provide a trickling filter and an immersion filter respectively at an upper part and a lower part of the tank, and sewage is supplied and circulated in the tank.
CONSTITUTION: Sewage is supplied into the cleaning tank A through an introducing pipe 8, and is sprinkled onto the trickling filter A
1 through a sprinkling pipe 10. When a sewage level WL is reached, the immersion filter A
2 is formed to obtain a steady state, a circulating pump 11 is operated to circulate the sewage between the trickling filter A
1 and the immersion filter A
2 , and a blower 14 is operated to forcibly feed air through a diffuser pipe 15. Air thus fed-in is supplied into one of left and right parts of the filter A
1 partitioned by a partition wall 2, flows upward to an upper part of the tank A as indicated by an arrow C while being accompanied by unpleasant odors generated through decomposition of organic matters during the cleaning process of the sewage, and is then introduced into a soil deodorizer 16 through a degassing pipe 16a, whereby the unpleasant odors are removed.
