Technical field
The utility model relates to a kind of water treating equipment, particularly a kind of strainer of organics removal.
Background technology
In order to make full use of the energy and saving water resource, the reuse water after municipal wastewater process becomes much industry and process water water source.Simultaneously due to the aggravation of environmental pollution, indivedual surface water water source is also subject to polluting eutrophication, and above water source all faces same problem as industry and process water water source, and organic pollutants exceeds standard.Its feature is that dissolved organic matter increases, their organic pollutant content lower than the emission standard of sewage work, but higher than organic pollutant content standard in city tap-water.
Treatment process at present for the organic pollutant of surface water adopts the modes such as aeration, filtration, charcoal absorption, chemical agent to remove.Conventional coagulation, precipitation, filter-sterilized are to the suspended substance in processed conventionally object mainly water, colloidal impurity and bacterium.Carry out advanced treatment to the precursor of the pollutent can not effectively removed by conventional treatment process or DBPs to be removed, to improve and to ensure water quality.Then can only by advanced treatment as the modes such as ozone oxidation, ozone and active carbon, ultraviolet be removed for Reclaimed Municipal Wastewater.For adopting reuse water or micro-polluted water as the industry at water source or process water preparation process, general employing pre-treatment---the full membrane process craft flow process of ultrafiltration---reverse osmosis---EDI, although full embrane method exists, equipment occupation of land is little, level of automation is high, operation is simple, use the advantages such as the little non-pollutant discharge of pharmaceutical chemicals consumption without soda acid, but still effectively cannot remove trace soluble organic pollutant in water.The serious consequence that existence runs the long-term stability of equipment and product water water quality causes of organic pollutant, the Organic pollutants of reverse osmosis membrane and microorganism dirt is caused to be blocked up, operating pressure increases, water production rate declines has to carry out matting, and matting causes the ratio of desalinization of reverse osmosis membrane to reduce frequently.To a certain degree just have to change reverse osmosis membrane in advance when reverse osmosis membrane is reduced to, cause unnecessary financial loss.Edi module is subject to Organic pollutants and then causes the exchange capacity of ion exchange resin in module to reduce, and desilication efficiency declines, and module internal resistance increases, and operating voltage increases, and running current reduces.Module inlet outlet pressure differential increases, and flow reduces.And the cleaning of sodium chloride solution can recover the ion exchange resin that blocked up by dirt, but all cannot remove organic pollutant, and the microorganism of degrading in the basic conditions and secretory product thereof are converted into small molecules organic pollutant is adsorbed by ion exchange resin and still cannot remove.The result of cleaning is the reduction of operation pressure reduction, the raising of product discharge of module, but the running voltage of module still remains high-order, and module internal resistance does not reduce.Therefore be necessary to remove micro quantity organic pollutant in equipment running process.Mode for the organism of reverse osmosis membrane and the common of microbial contamination adopts non oxidizing bactericide to block up to prevent microbial contamination and the dirt that causes thereof, carry out matting if desired, therefore the cycle short then girth continued due to the resistance of microorganism then to two months, generally at about 20 days.And reverse osmosis acts on without removal the organic pollutant of nonelectrolyte, some organic pollutants inevitably enters the normal operation of next unit EDI influential system.And for EDI system, can adopt pickling, sodium-chlor cleaning, 0.04% the measure process such as peracetic acid disinfectant, if but oxygenant controls improperly may to cause ion exchange resin, the irreversible oxidation of film causes structure deteriorate.Should be understood that above measure all belongs to post measure but not preventive measures simultaneously.
Micro quantity organic pollutant (TOC) in water is removed for adopting ozone oxidation and ultraviolet degradation in the ultrapure water preparation process of semiconductor technology, except the problem that equipment price high working cost is high, ozone also may cause the oxidation of ion exchange resin, film due to ozone dosage problem.Same ultraviolet degradation, owing to may produce the oxidation that ozone also may cause ion exchange resin, film in the ultraviolet Water Under of 180 nanometers.Therefore be necessary in full embrane method system, to select necessary technology and equipment to remove before organic pollutant enters reverse osmosis membrane/EDI module.
Utility model content
The purpose of this utility model is to provide a kind of strainer of organics removal and method and ultrapure water preparation method, and the organic pollutant that solve in water manufacturing system to the pollution of reverse osmosis membrane, EDI module, can reduce the technical problem in the work-ing life of equipment; And solve the high problem of equipment price high working cost.
