Description
Technical field
The present invention relates to a kind of continous way intelligent control photochemical catalysis profound purification device.
Background technology
As everyone knows, adopt chlorine do oxygenant to tap water carry out disinfection, sterilization has its deadly defect, promptly can generate multiple chlorinated organics such as intermediate product trichloromethane, monochloroethane, tetracol phenixin, these bring the organism of secondary pollution is priority pollutants mostly, can be detrimental to health after drinking.With ozone to tap water carry out disinfection, sterilization is than chlorine safety, but also can form some virose intermediate products, and ozone hold time short, the water quality mouthfeel is bad, the cost height.Carry out advanced treatment with methods such as charcoal absorption, high molecular filter element filtrations, can only remove macrobead suspended substance, mineral ion and partial organic substances in the water, it is low that small organic molecules such as trichloromethane, monochloroethane, tetracol phenixin are removed efficient, and often need more renew cartridge.So the water depth treatment effect of aforesaid method is all undesirable, the water quality after the processing can not reach direct standard for drinking substantially.Carry out the tap water advanced treatment with the RO reverse osmosis method, though can reach the direct-drinking water standard, have also that trichloromethane removes that efficient is low, needed by human body micro-ly is filtered removals, the water quality after handling is that slightly acidic, water loss are very big, investment greatly, problem such as running cost height.Also because of like this, the photochemical catalysis water technology has obtained very fast development.
Semiconductor light-catalyst generates strong oxidizer OH-, OH-and H under UV-irradiation
2The O molecular oxygen changes into the OH free radical, and the oxidation capacity of OH free radical is that defluorination is outer the strongest in the oxygenant that exists in the water body, can most organic pollutant of oxidation and part inorganic pollutant, and be CO with its eventual degradation
2, H
2Innoxious substances such as O make profound purification reach the direct-drinking water standard.At present, the water quality advanced processing of photochemical catalysis both at home and abroad can be divided into suspension system and fixed structure substantially according to the structure of hydrogen-catalyst reactor.The suspension system reactor catalyst reclaims difficulty and is difficult to extensive practicability, and the fixed structure adopts the carrier plated film more or smears mode, exists surface in contact to amass little inefficient problem.Day disclosure specially permit flat 4-141294 with porous sintered material or photoconductive fiber as support of the catalyst, increase surface-area, but very most of illumination less than, and it is impracticable to cost an arm and a leg.China's utility model patent 95244568 discloses a kind of fixedly film photocatalytic oxidation profound purification device, China's utility model patent 96251030 discloses a kind of photochemical catalysis water quality treater, patent of invention CN1257838 discloses the method and apparatus that the continuously photocatalytic catalytic purification contains organic pollutant waste water and tap water and has adopted suspension system to realize handling continuously, these patents have some common ground be exactly (1) thus need add agitator brings source of pollution, noise, failure rate to rise; (2) long reaction time is difficult to accomplish continuous processing; (3) sealing difficulties such as support of the catalyst, fluorescent tube protective tube and upper and lower ends; (4) processing power is little, the dilatation difficulty; (5) because the intelligent control that is unrealized then exists lamp to break the possibility that also continues operation, can cause mistake to drink the problem of the water quality that is untreated, practical application is difficult to guarantee safety; (6) complex structure, inconvenient installation and maintenance.
