Abstract
The invention relates to a pretreatment method for the cycling treatment of urban car-washing wastewater; firstly, a cyclone separator is used for separating particulate matter, sediment and the substances the specific gravity of which is larger than water, out of urban car-washing wastewater, then a water pump is used for carrying out pressurization to the water after separating treatment, the granules, the diameter of which is more than 5Mum, are filtered by a cross-flow membrane method, and then the filtered water is treated with aeration and oxygen increasing as well as biodegradation. The invention also discloses a device for realizing the method; the device is composed of the cyclone separator, a cross-flow membrane filter, an aeration and oxygen increasing vessel and a biodegradation vessel; a treated water outlet pipe of the cyclone separator is connected with a booster water pump and an outlet pipe of the booster water pump is connected with the cross-flow membrane filter. The method of the invention can obtain the clean water which can fully meet the water quality requirements of a water cycle treatment machine, effectively solve the problem of black and odorous effluentand save water resources.
Description
Technical field:
The present invention relates to water treatment device, relate in particular to city car-washing water cycle handler, pretreatment process and device that particularly a kind of city car-washing water cycle is handled.
Background technology:
Contain particulate matter, silt and other proportion material in the city car-washing waste water greater than water.In the prior art, the city car-washing water cycle handle to adopt the method for micro-filtration and ultrafiltration, owing to contain the impurity large percentage in the city car-washing waste water, so micro-filtration and ultrafiltration apparatus be difficult to long-time running, causes water body black smelly.
Summary of the invention:
The purpose of this invention is to provide the pretreatment process that the city car-washing water cycle is handled, the pretreatment process that described this city car-washing water cycle is handled will solve the unfavorable technical problem of city car-washing water cycle treatment process in the prior art.
The pretreatment process that this city car-washing water cycle of the present invention is handled comprises the process of a separating impurity from city car-washing waste water, described impurity is particulate matter and the proportion material greater than water, wherein, described from city car-washing waste water in the process of separating impurity, at first utilize cyclone separator that particulate matter and the proportion material greater than water is separated from city car-washing waste water, utilize water pump that the water body through separating treatment is pressurizeed then, utilize the cross-current type embrane method to filter out the granule of diameter more than 5 μ m in the water body again, again the water body through filtration treatment is carried out aeration oxygen replenishing processing and biological degradation processing.
The present invention also provides a kind of device of realizing the pretreatment process that above-mentioned city car-washing water cycle is handled, described this pretreatment unit is by cyclone separator, the cross-flow type membrane filtration device, aeration oxygen replenishing container and biological degradation container constitute, wherein, the treating water rising pipe of described cyclone separator is connected with a booster water pump, the rising pipe of described booster water pump is connected with described cross-flow type membrane filtration device, the rising pipe of cross-flow type membrane filtration device is connected with described aeration oxygen replenishing container, the rising pipe of aeration oxygen replenishing container is connected with described biological degradation container, is connected with the cleaning water rising pipe on the biological degradation container.
Further, be provided with the lifting water pump between the rising pipe of described aeration oxygen replenishing container and the biological degradation container.
Principle of work of the present invention is: owing to contain particulate matter, silt and other proportion large percentage greater than the material of water in the city car-washing waste water, therefore can not directly enter the water cycle handler.The present invention at first utilizes cyclone separator that particulate matter and the proportion material greater than water is separated from city car-washing waste water, can obtain the extraction water yield of larger proportion, utilize water pump that the water body through separating treatment is pressurizeed then, utilize the cross-current type embrane method to filter out the granule of diameter more than 5 μ m in the water body again, again the water body through filtration treatment is carried out aeration oxygen replenishing processing and biological degradation processing, the cleaning water of Huo Deing can satisfy the water quality requirement of water cycle handler fully at last.
The present invention and prior art contrast, and its effect is actively with tangible.The present invention utilizes cyclone separator that particulate matter and the proportion material greater than water is separated from city car-washing waste water, thereby obtain the extraction water yield of larger proportion, pressurization then, utilize the cross-current type embrane method to filter again, carrying out aeration oxygen replenishing processing and biological degradation again handles, can obtain to satisfy fully the cleaning water of water cycle handler water quality requirement at last, efficiently solve the black smelly problem of water outlet, save water resources.
