Abstract
A process for treating water by catalytic ozonization method includes such steps as pre-treating the water to be treated, catalytic ozonization by using the graphite or the active substance carried graphite as catalyst instead of activated carbon, and post-treating. It can oxidize the organic pollutants to become CO2 and H2O.
Description
Technical field
The present invention relates to a kind of water treatment method.
Background technology
Along with the pollution level of development of industry and agriculture surface water also increases the weight of day by day, the organic pollutant of the overwhelming majority is difficult to effectively remove by self-purification of waters in the water, and these organic pollutants (as agricultural chemicals, algae toxin, organic solvent) are carcinogenic, teratogenesis, mutagenic material or endocrine disruptor mostly, if handle not thoroughly with the serious harm HUMAN HEALTH.Be difficult to effectively remove the organic pollutant of all kinds of high stabilities in the water separately with the ozone oxidation water technology, and the organic acid that the organic pollutant oxidation does not thoroughly generate can produce a lot of disinfection byproduct (DBP) in aftertreatment (chlorination) process; In addition, organic acid also can influence water supply network water quality as causing the excessive breeding of bacterium by biological assimilation organism in pipe network.Some water factories adopt the catalytic ozonation water technology at present, improved the clearance of the organic pollutant in the water, but because catalyzer mostly is gac greatly, and gac exists easily by ozone oxidation decomposition, low, the breakable defective of intensity, so the gac life cycle is short, and need to increase cut-off equipment to remove the fine particle that produces after the gac fragmentation.
Summary of the invention
The objective of the invention is in order to solve in the present catalytic ozonization water treatment method with the gac is catalyzer, exist gac easily by ozone oxidation decomposition, low, the easy fragmentation of intensity, the problem of cut-off equipment is lacked and needed to increase to life cycle, and a kind of catalytic ozonization water treatment method that provides.Catalytic ozonization water treatment method: pending water carries out pre-treatment earlier, carries out catalytic ozonation again and handles, and gets final product water outlet through aftertreatment then; The mol ratio of ozone and catalyzer is 1: 0.01～5 in the catalytic ozonation treating processes, the ozone dosage is 0.1～1000mg/L, flow velocity is 1～20m/h in the catalytic ozonation reactor, be 5s～300min the duration of contact of ozone and catalyzer and water, and wherein catalyzer is the graphite of graphite or supported active thing.Because of graphite has laminate structure, intensity is big, difficult broken, chemical stability is strong, difficult is decomposed cheap advantage by ozone oxidation, be more suitable for share and carry out the catalytic ozonation water treatment with ozone, life cycle is long, is 5～50 months, need not increase, transform existing water treating equipment.The present invention with the graphite of graphite or supported active thing as catalyzer, the clearance of organic pollutant is more than 55% in the water treatment procedure, and organic pollutant can be oxidized to carbonic acid gas and water, avoid the generation of intermediate products such as organic acid, reduced the possibility of the excessive breeding of bacterium in the generation of disinfection byproduct (DBP) in aftertreatment (chlorination) process and the pipe network.
