Embodiment Construction

[0015] Below in conjunction with accompanying drawing, the present invention will be further described:

[0016] Such as figure 1 Washing basin 1 in toilet washes and drains through grille basket 2 to trap large particles, hair and solid particles with a diameter greater than one millimeter, and then enters water collection tank 3. Water collection tank 3 collects washing and drainage for preliminary sedimentation, and then clears the upper part The liquid is sent to the biochemical treatment tank 4. In the biochemical treatment tank 4, the washing drainage is in contact with activated carbon and oxygen, and the large porosity of the activated carbon and oxygen are used to generate an active biofilm to remove the organic matter in the washing drainage. The washing drainage passes through the grid basket After 2 and the biochemical treatment tank 4, its water quality reaches the water quality standard of reclaimed water, and the washed drainage after the treatment is stored in ...

Abstract

The present invention relates to sewage purifying and re-utilizing method and device, and is especially washing water purifying and re-utilizing method and device for train passenger car. There are lattice basket between the drainage pipe of the washing basin and the biochemical processing tank, water passage between the biochemical processing tank and the middle water storage tank, membrane processing unit between the middle water storage tank and train water tank, and flushing water pressurizing unit connected to the middle water storage tank and the train water tank. The washing water is processed into intermediate water for flushing toilet and the excessive intermediate water is further processed into drinking water and returned to the train water tank. The present invention can save water over 50%.

Description

technical field [0001] The invention relates to a method and a device for purifying and reusing sewage, in particular to a method and a device for reusing washing and drainage of train passenger carriages. Background technique [0002] For a long time, the water supply for passenger trains in my country, including passenger washing, washing, drinking and toilet flushing, has been supplied by on-board water tanks. Due to the limited volume of the on-board water tank, it cannot meet the water demand of passengers; trains need to stop at stations frequently to replenish water, resulting in many stops and long stops, which seriously affects the efficiency of train operation. At the same time, the washing and washing water for passengers is directly discharged; the toilet flushing water is directly supplied by the water tank. cause waste of water. Contents of the invention [0003] The purpose of the present invention is to provide a method and device for reuse of washing and...
