Background technology
In life, people are more and more higher for the requirement of water environment now. Therefore, for sewagePurified treatment be gradually valued by the people. In order to realize for using dirty water purification, occurVarious cleaning system, because the clean-up effect of hyperfiltration treatment system is very remarkable, therefore comesMore factory, workshops etc. bring into use ultrafiltration system to process trade effluent. By to water bodyPressurization is delivered to opposite side by sewage by a side pressure of filtering permeable membrane, the impurity, the bacterium that in water body, existDeng excessive and cannot pass filter membrane due to diameter, be left on water inlet one side, thereby at two of filmSide forms different waters, is dense pool on one side, is clean water area on one side, and realization is clean to sewageChange and process. But, because the dustiness of industrial wastewater is larger, only by this processing of ultrafiltration,Can't remove completely for the refuse existing in the phase, after such water enters the external world, stillEasily water pollutes to external world. And in the long-term process using, the filter of dense pool one sideThe surperficial impurity of film can constantly be piled up, last fouling, thus stop up filter membrane, make waterThe purification of body cannot continue again. Common way is that the water having purified is carried out to backwash to film,The impurity punching of fouling on film is fallen, make water can continue again to filter by film. And quiltFor the water of backwash, together discharge with rushing fallen impurity. But such way pairCaused very large waste in the water of backwash, resource utilization is lower, waste water resource. HaveAlthough a little treatment systems are provided with the water of backwash are reclaimed, for locating of recycle-waterManage perfect not, thereby make recycle-water bring too much impurity into Yuan Shui in mixing with former waterIn, strengthen the workload for the treatment of system, reduce operating efficiency.
