Embodiment Construction

[0032] An integrated feces and sewage treatment device for a train closed toilet toilet, the implementation method of which is as follows:

[0033] 1.1 Operation of the processing unit

[0034] First, the feces are stored in the feces storage tank 1, and then the fecal sewage is sent into the electric assisted oxidation tank 4 through the submersible sewage pump 2; Internal circulation anoxic biological pool 6; the sewage passes through the internal circulation anoxic biological pool 6 from top to bottom, and then a part of the sewage is sent into the The electrocatalytic coupling aerated biological contact tank 8, and the other part returns to the internal circulation anoxic biological tank 6; the sewage is connected to the clean water storage tank 12 through the electrocatalytic coupling aerated biological contact tank 8 through the outlet pipe, and finally the treated sewage Then store in the clear water storage tank 12 after the disinfection treatment of the disinfection ...

Abstract

The invention discloses a train sealed-type toilet urinal fecal sewage integrated treater and a treating method thereof, which relate to sewage integrated treatment and is particularlly suitable for treating fecal sewage in train sealed-type toilet urinals. The invention aims to solve the problems of complex treatment process, high cost and difficulty in discharge after reaching standards in the passenger train sealed-type toilet urinals. The invention integrates the electric assisted oxidation treatment, internal circulation anaerobic treatment and electrocatalysis coupling aeration biological contact tank, so that fecal sewage is firstly electrochemically combusted by a electric assisted oxidation pond to mineralize organic substances; then, the discharged water enters the internal circulation anaerobic treatment for denitrification; the discharged water is biodegraded through the electrocatalysis coupling aeration biological contact tank to remove the organic substances COD and NH3-N; and finally, the discharged water is sterilized by ozone, thereby reaching the first-grade emission standard GB8978-1996. The invention is used for treating fecal sewage in cities, high concentration organic waste water and train sealed-type toilet urinal fecal sewage.

Description

technical field [0001] The invention relates to an integrated treatment device for sewage, which is especially suitable for the integrated treatment device for feces and sewage in closed toilets of trains. Background technique [0002] In order to protect the ecological environment along the railway, many developed countries in the world have begun to install a large number of toilets on the trains since the 1970s to collect passenger excrement and avoid random excretion along the railway. Receiving and processing facilities. In developed countries, the urban sewage pipe network and treatment system are very complete and the population is relatively small. Therefore, the collected feces are generally discharged to the urban sewage pipe network after simple treatment, and then sent to the urban sewage treatment plant for mixed treatment with urban sewage before discharge. It is seldom that the toilet sewage is treated separately and discharged directly. Although some countr...
