Description
Technical field
The invention belongs to water-treatment technology field, relate to the method that water pollutant is drunk in a kind of removal.
Background technology
Along with economy and industrial expansion, the chronic pollution of water resources is day by day serious, and meanwhile, growth in the living standard is also so that people require increasingly stringent for the safety control of tap water.The exploitation of novel material new technology increases the pollutant kind in the water surrounding day by day, Micropollutants such as aniline category matter in the water, phenols endocrine disruptors and benzotriazole light stabilizer have proposed stern challenge to traditional water technology, experimental study both domestic and external and actual production operation result show, is subjected to water body that above three class materials pollute can only reach 20 ~ 30% by coagulation, precipitation, filtration, the sterilization process of routine to the clearance of Micropollutants.Therefore, in order to ensure drinking water safety, need in conventional procedure, introduce pre-oxidation process or advanced treatment process.
Mainly contain liquid chlorine, dioxide peroxide, ozone and potassium permanganate etc. at present oxidation medicament commonly used in the water treatment.Than other several oxidation medicaments, potassium permanganate can not produce poisonous and hazardous disinfection byproduct (DBP), and its reduzate Manganse Dioxide has absorption, helps the effects such as solidifying, can strengthen removal of pollutants in the water body, and be easy to separate, in addition, potassium permanganate is convenient to transportation storage, easy to use.But the rate of oxidation of potassium permanganate is lower, obtain the removal effect identical with liquid chlorine, dioxide peroxide or ozone, and the oxidization time and the dosage that need can increase, the increase that has therefore also just brought capital construction cost and working cost.
The result of the research in early stage shows, most of oxygenant in the water supply process can not be with the organism permineralization, in the process of potassium permanganate (250 μ M) oxidation dihydroxyphenyl propane (25 μ M), the clearance of TOC only is about 50%, and along with the growth of oxidization time, the clearance of TOC changes little.Also have similar phenomenon in the ozone oxidation process, when oxidization time prolonged 4h, the clearance of TOC had only improved 16%.Therefore we infer, although the parent of Micropollutants has obtained removing preferably in oxidising process, and the more difficult mineralising of intermediate product that these parents transform, and the toxicity of these intermediate products is mostly still unknown.With the detoxification of Micropollutants, the most safe and reliable method is with the thorough mineralising of the intermediate product of these difficult degradations, is converted into CO for fully
