Problems solved by technology

Since the reacted water directly enters the membrane device, the photocatalyst is directly deposited on the membrane surface, which accelerates membrane pollution, and frequent backwashing will also reduce the life of the membrane, requiring constant replacement of new membranes, which makes the operating cost too high. Can't promote the app well
Chinese invention patent (00103229.1) also introduces a related "suspension photocatalytic oxidation water treatment method and its device combined with membrane separation equipment". Compared with the above patents, there are improvements. The sedimentation area reduces the load on the membrane and solves the backwashing problem of the filter membrane to a certain extent, but the disadvantages are also obvious: the sedimentation area is only a space above the reaction area without any sedimentation facilities, and its function is equivalent to static Heavy, and the boundary with the reaction zone is not obvious, the precipitation effect is questioned, whether it can really effectively reduce the load on the subsequent membrane treatment also makes people put a heavy question mark in their hearts
In addition, in order to realize the suspension of catalyst particles, these two inventions are equipped with diversion devices inside the reactor, and some are equipped with stirring devices and air supply devices inside the reactor at the same time, which makes the internal structure of the reactor too complicated and increases the construction cost. Difficulty, most of the equipment occupies the effective reaction space inside the reactor, which affects the degradation efficiency of organic matter

Description

technical field [0001] The invention relates to a photocatalysis and membrane filtration water treatment system. The system can effectively remove organic matter in water, and does not require frequent backwashing. It is suitable for the treatment of various refractory organic wastewater, high-concentration, high-color organic wastewater, advanced treatment of drinking water, terminal treatment and pretreatment of high-purity water, etc. . Background technique [0002] The rapid development of modern industry in recent decades, especially the rapid development of synthetic chemical industry, has led to a sharp increase in the types and output of artificially synthesized organic compounds. They enter the human environment, especially the water environment, through different ways, causing significant changes in the physical and chemical properties of the receiving water. According to statistics, there are as many as 96,000 kinds of organic pollutants in the water environment...
