Filtration efficiency and capacity of the sewage treatment interception devices are superior to the traditional media, mainly apply to turbidity filtration process. Membrane filtration: Wastewater Reuse common membrane filtration are: microfiltration, ultrafiltration, nanofiltration, reverse osmosis and other sewage indicators, each of which has specific membrane technology performance and scope. Modification of Materials: Modified Media is the media by a chemical reaction of a surface coated with modifiers, which alter the physical and chemical properties of the original filter surface to improve the adsorption capacity of the filter sewage interception, to improve water quality. As a solid-liquid separation by filtration method in the field of water reclamation and reuse process is widely used. Currently, according to the nature of the filter material can be divided into the following five forms: traditional natural materials: such as quartz sand, anthracite, shell and so on. Quartz sand is applied more widely used as a filter. Synthetic materials: synthetic filter media currently used polystyrene beads, PVC beads, polypropylene beads. Fiber filter: fiber filter using a new type of sewage treatment equipment tow or fiber ball as a filter unit. Guangzhou-Foshan, Shunde Xingtan students environmental municipal wastewater treatment works (36000m3 / d): sewage treatment works Technology (1) artificial biological purification artificial biological purification, is artificially creating conditions for microbes multiply, domesticated microbe, using microorganisms The method of organic compounds in water quality degradation metabolism is the process of soil secondary treatment of sewage at home and abroad recently. The main advantages are: stable treatment effect, you can adjust the processing efficiency in a certain range, sewage treatment technology company, felled and small size. The main disadvantages are: high investment, high operating costs, management complexity sewage picture, the operator need more. The main treatment process is as follows: a sewage sedimentation (or flotation) a biofilm a biofilter (rotating biological contact oxidation, activated sludge) an aeration tank (oxidation ditch) sedimentation (or flotation) a disinfection an outlet (2) natural biological purification of natural biological purification process, the main use of pollutant concentration in soil microorganisms and plant roots or pond of microorganisms so that the water is reduced. The main advantages are: low investment (land acquisition costs 10,000 yuan / hm case), low operating costs, simple to manage, less operators needed. Can be used alone, but also with each other to form a coalition deal with the system. Disadvantages are: large-felled area. The main treatment process is as follows: a precipitate of a sewage lagoon (land treatment) a rapid infiltration (full speed infiltration, overland flow) sewage treatment process, Shantou sewage, rich students provided by the Guangzhou Environmental Protection Engineering Co., rich students.
