The setting of ozone filler improves the treatment efficiency and effect of ozone catalytic pool 44, and ensures the sanitary safety of effluent.

[0034] The working principle of the railway construction camping car environment-friendly storage device is as follows: after a user uses the squatting toilet 11 to defecate, flushing water and sewage enter the elevator 3 through a vacuum or pressure system, the mixture is lifted to a proper height by the elevator 3, and then is transported to the first sewage storage tank 2 through a pipeline for primary solid-liquid separation. In the first sewage storage tank 2, solid waste is preliminarily separated from liquid, and then the supernatant enters the second sewage storage tank 21 for secondary solid-liquid separation, and further residual solid particles are removed. The supernatant after the secondary separation is precisely filtered through the security filter, and then is temporarily stored in the intermediate tank 22. The supernatant in the intermediate tank 22 is lifted to the biochemical tank 4 by the lifting pump 41 for subsequent treatment. In the biochemical tank 4, the supernatant is subjected to micro-electrolysis by the micro-electrolysis filler, and organic substances such as BOD5 and CODcr in the sewage are effectively degraded. The treated sewage flows into the ceramic membrane tank 42, and the first air pump 43 provides aeration to the biochemical tank 4 and the ceramic membrane tank 42 through the air conveying pipe to provide oxygen, stirring and prevent sedimentation. The ceramic membrane bioreactor performs membrane filtration treatment on the sewage, and retains small particles and organic matter, so as to ensure the clarity and sanitary safety of the effluent. Then, the suction pump 45 sucks the treated water in the ceramic membrane tank 42 into the ozone catalytic tank 44. The second air pump 46 and the ozone generator convey ozone to the ozone catalytic tank 44 through the ozone pipe, and the ozone reacts with pollutants in the sewage to realize deep oxidation, deodorization and disinfection. The ozone filler further enhances the oxidation capacity of ozone and promotes the reaction of ozone and pollutants in the sewage. The effluent after the ozone catalytic treatment can be recycled for flushing, so that efficient use of water resources and environment-friendly emission are realized.
