Description

A kind of water body purification preparation method of charing adsorption particle

Technical field

The present invention relates to water-treatment technology field, be specifically related to the preparation method of a kind of water body purification with the charing adsorption particle.

Background technology

The acceleration with urbanization process of developing rapidly along with industrial or agricultural; industrial wastewater and sanitary sewage discharge capacity increase day by day; make the water environment pollution problem be on the rise; therefore; polluted water purification has become the significant problem that needs to be resolved hurrily that concerns national economy; China and governments at all levels improve constantly the environmental protection attention degree; annual input is hundreds billion of to be used for sewage disposal and water body purification, but present sewage treatment capacity, technical merit and Related product development also far can not be satisfied the needs that actual sewage is handled and purified.

Correlation technique and patent that water pollution is removed and purified are of a great variety, comprise the physical method based on counter-infiltration, distillation, soil irrigation; Based on the chemical method of ion-exchange, ammonia stripping, chemical precipitation method, breakpoint chlorination, electrodialysis, electrochemical treatments, catalytic pyrolysis, these methods are mainly used in sewage treatment plant.And at present mainly adopt based on the biological method of microorganism cultivation, algal culture and artificial swamp at the pollution restorative procedure of natural waters such as river pollution, city river and lake etc.Main mandate or disclosed patent comprise: enhanced compounded mix multi-stage alternate wetland sewage treating process and device thereof (CN200710190227.7), waterborne artificial wetland and process for purifying water (CN200710053250.1), municipal sewage artificial swamp floriculture method (CN03114217.6), artificial wet field facilities for treating sewage (CN02134344.6), recover the engineering method (CN200410010692.4) on degeneration riverbank with reed, Small Sewage Treatment Equipment and technology thereof (CN88103355.3) etc.Pollute treatment technology because its construction cost is low based on the natural water of artificial swamp, convenient management and have ecoscape and be worth and be widely used.Artificial swamp mainly is made up of matrix, plant and microorganism, and matrix is as the carrier that adsorbs pollutant and plant, growth of microorganism, most of physics, chemistry and biological respinse etc. all carry out in matrix, construction has central role (Xu Defu, Li Yingxue for artificial swamp, be used for matrix, plant and the configuration thereof of the artificial swamp of sewage disposal, the wetland science, 2007,5 (1): 32-38).The matrix that artificial swamp adopts mainly is that natural material mainly contains dolomite, lime stone, wollastonite, zeolite, shale, bauxite, sand and gravel, dirt, soil, opoka, shell sand; Industry byproduct mainly contains blast-furnace cinder, electric arc furnaces slag, slag, slag, flyash; Artificial product mainly is meant the lightweight expansion flight of steps leading to a palace hall gather materials clay (Ruan Jingjing, Gao De, Hong Jianming, artificial swamp matrix progress, Capital Normal University's journal (natural science edition), 2009,30 (6): 85-90).These matrix are mainly based on inorganic material, and quality is heavier, adsorption capacity is less, easily cause artificial swamp to stop up, and have a strong impact on the service life of artificial swamp, limited promoting the use of of artificial swamp.And the development adsorption capacity big, hold back effective, the long-acting lasting novel wetland host material of performance, become the key of development artificial swamp technology.

Summary of the invention
