Sewage treatment equipment and drainage stormwater intake type sewage collection system

摘要

PROBLEM TO BE SOLVED: To apply the results of biotechnology to the current sewage collection technology. SOLUTION: The sewage water collecting treatment device (1) is configured so that the outer tub (1) is separated from the first inner tub (1.2) by a partition wall (1.4) so that the decomposition, recombination and decomposition processes of microorganisms function properly. And the second inner tank (1.3), the first contains the heterotrophic microorganism growth medium, and the second inner tank (1.3) contains the autotrophic and heterotrophic microorganism growth medium. Is done. In addition, the system for buildings that collects and treats discharged rainwater is (1) one or more of the above devices, and (2) indoor piping consisting of a main vertical pipe that collects and transports wastewater and rainwater, and a substantially horizontal branch pipe. (3) Consists of an outdoor piping system consisting of horizontal pipes that transport rainwater and sewage. The outdoor piping system connects the indoor piping system and one or more sewage treatment apparatuses.
