Suspended fecal sewage solid-liquid separation device

Abstract

The invention relates to a suspended fecal sewage solid-liquid separation device which comprises a box body, a solid-liquid stirring mechanism and a conveying mechanism, wherein the inside of the box body is provided with a first cavity for carrying out solid-liquid separation on fecal sewage, a second cavity body which is used for conveying the separated solids and communicates with the first cavity, and a third cavity for collecting the separated sewage; the first cavity is provided with a feed port and an exhaust port; the second cavity is provided with a slag outlet; the first cavity is filled with a biological filler; the solid-liquid stirring mechanism is arranged corresponding to the first cavity, and used for stirring and mixing the biological filler and fecal sewage, and conveying the separated solids to the second cavity; the conveying mechanism is arranged corresponding to the second cavity and used for conveying the solids out of the slag outlet; the bottom of the first cavity is provided with sieve pores through which the separated sewage flows into the third cavity; and the third cavity is provided with a discharged sewage outlet. The suspended fecal sewage solid-liquid separation device is suitable for miniaturized production, thereby saving the installation space, and facilitating the real time treatment on sewage.

Description

Technical field [0001] The invention relates to the technical field of rail transportation equipment, in particular to a hanging type fecal sewage solid-liquid separation device. Background technique [0002] In recent years, with the rapid popularization of EMU trains, the direct-draining toilets of traditional passenger trains have gradually been replaced by closed toilets. This closed toilet with toilet traps collects urine, feces and other dirt at the bottom of the carriage. The sewage tanks are stored and prepared when the train arrives at the station, and collected by the suction truck or ground receiving system during maintenance. The conditional stations simply treat the collected fecal sewage and discharge it into the urban sewage pipe network or the urban fecal waste disposal station, while the sites with poor centralized treatment of fecal sewage will be transported by the local sanitation or established by the site separately The sewage treatment facilities are treat...

AI Technical Summary

Problems solved by technology

[0003] It is difficult to directly and real-time treat feces and sewage generated on passenger trains at the present stage. For example, the Chinese utility model patent "A Vehicle-mounted Feces Treatment Device" whose authorized announcement number is CN203392988U (application number is 201320503246.1), in which the disclosed feces treatment device needs to be carried on a vehicle. For use near septic tanks, not for use on trains

[0004] Authorized announcement number is CN201793435U (application number is 201020238159.4) Chinese utility model patent "Environmental Protection and Water-saving Feces Processor for Vehicles", in which the disclosed feces processor can be installed on the train for use, but it needs to use a dry heater to The solid matter in the feces is dried, and the energy consumption is high, and the degradable solid matter in the feces sewage cannot be effectively treated, which increases the processing load and difficulty of the subsequent sewage treatment equipment
