Sewage treatment process: biological oxidation process incorporates new biological contact oxidation process at home and abroad, the new technology advantages, the common advantages of both activated sludge, biofilm process, the use of advanced combination of fillers, organic load is high, high removal efficiency of COD and BOD. Biological contact oxidation system consists of the tower, packing, aeration system and water system. Sewage from the bottom to enter into contact with the biofilm on the packing township sewage using microbial oxidation, the decomposition of organic matter in sewage small sewage treatment process, has to purify the water quality requirements. Aeration blowers by using bulk flow aeration head aeration sewage, even small bubbles achieve the purpose of increasing the dissolved oxygen for aerobic microbial growth, reproduction and oxidative decomposition of organic matter in water. Guangzhou Fu students Environmental Accor new Electronics (Dongguan) Co., Ltd. sewage treatment works (1800m3 / d): filtration efficiency and capacity of the sewage treatment interception devices are superior to the traditional media, mainly apply to turbidity filter process. Membrane filtration: Wastewater Reuse common membrane filtration are: microfiltration, ultrafiltration, nanofiltration, reverse osmosis, membrane technology each has specific performance and scope. Modification of Materials: Modified filter through a chemical reaction on the surface of the filter is coated with modifiers, which alter the physical and chemical properties of the original filter surface to improve the adsorption capacity of the rejection filter sewage treatment projects 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 program, Quanzhou sewage, rich students provided by the Environmental Protection Engineering Co., Ltd.
