Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] Such as figure 1 As shown, an integrated treatment system for the harmlessness and resource utilization of train unloading feces and sewage, the implementation method is as follows:

[0030] 1.1 Process flow of the system

[0031] Firstly, the fecal sewage from train unloading is stored in the fecal storage tank, and then the fecal sewage is sent to the centrifuge through the submersible sewage pump; the fecal sewage is separated from the solid and liquid through the centrifuge, and the solid enters the hydrolysis tank through the pipeline, and the solid is hydrolyzed The hydrolysis reaction occurs in the pool, and the supernatant enters the feces storage tank through the water pipe; the filtrate enters the intermediate tank through the pipeline, and then the submersible pump in the intermediate tank sends the sewage into the struvite recovery s...

Abstract

The invention discloses a harmless and recycling integrated treatment system for discharged fecal sewage of a train. The system comprises a pretreatment system, a resource recycling system, a treatment system and a sterilizing system, wherein the pretreatment system is connected with the resource recycling system, the resource recycling system is connected with the treatment system, and the treatment system is connected with the sterilizing system; the pretreatment system comprises an excrement storage pool, a hydrolysis acidification pool and a centrifugal separator; the excrement storage pool is connected with the hydrolysis acidification pool in parallel, and the top of the hydrolysis acidification pool is provided with a water passing pipe which is communicated with the excrement storage pool; a submersible sewage pump is arranged in the excrement storage pool, and the excrement storage pool is connected with the centrifugal separator through the submersible sewage pump; the centrifugal separator is respectively connected with the hydrolysis acidification pool and the resource recycling system through a slag outlet pipe and a water outlet pipe. By adopting the integrated treatment system, not only can the recycling of ammonia nitrogen and phosphate in the fecal sewage be realized, but also the content of ammonia nitrogen and phosphate in the sewage entering the subsequent procedures can be reduced, so that the sewage is easier to treat and likely to reach the standard, and the cost is reduced.

Description

technical field [0001] The invention relates to an integrated treatment system for the harmless and resourceful recovery of excrement and sewage from train unloading. Background technique [0002] In order to protect the ecological environment along the railway, developed countries in the world have begun to install toilets on trains since the 1970s to collect passenger excrement and avoid environmental pollution caused by random discharge along the railway. Feces receiving and treatment facilities. Domestic passenger trains have been installed with toilets for a short period of time, and there is a complete sewage discharge system, but there is no matching high-concentration fecal sewage treatment technology and equipment. For this kind of fecal sewage, it is mainly handed over to the local sanitation department for treatment in China. At present, judging from the treatment situation, the treatment process is complicated, the operation status is poor, and the discharge can...
