Embodiment
[0045] Such as Figure 1-Figure 2As shown, the sewage first enters the anaerobic pool 1, and in the anaerobic pool 1, the phosphating microorganisms use the organic matter in the sewage to release phosphorus in the body and remove part of the organic matter, and then the sewage enters the denitrification and denitrification pool 2, where denitrification is carried out Remove the total nitrogen, then 50% of the sewage enters the anammox tank 3, and 50% of the sewage enters the nitrification reaction tank 4, and the anammox reaction occurs in the anammox tank 3 to remove the total nitrogen, and the nitrification reaction Nitrosation reaction occurs in the pool 4, and the ammonia nitrogen in the sewage is converted into nitrite; then the sewage enters the anammox tank 3, and after the reaction in the anammox tank 3, the effluent enters the anoxic pool 5, where the remaining organic matter is further removed , the organic nitrogen in the remaining organic matter is converted into ...

The invention belongs to the field of sewage processing, and especially relates to a c ceramic membrane sewage nitrogen and phosphorus removing regeneration recycling control method and a system. According to the ceramic membrane sewage nitrogen and phosphorus removing regeneration recycling control method, combination of sewage processing short-cut nitrification and denitrification, anaerobic ammoxidation, ceramic flat plate membrane separation, and active alumina adsorption phosphate removing technology is adopted, so that sewage deep processing is realized, and regeneration recycling of discharged water is realized. Short-cut nitrification and denitrification and anaerobic ammoxidation are adopted to realize deep nitrogen removing, cost of a carbon source added for nitrogen removing isreduced, and aeration energy consumption is reduced. Ceramic membrane analysis technology is adopted to realize enrichment and reinforcement of dominant microbial flora in the system, active alumina is adopted for adsorption of total phosphorus left in sewage, so that the total phosphorus concentration of discharged water is lower than 0.05mg / L. A polymeric aluminium chloride salt is added, so that phosphorus in sewage is converted into aluminium phosphate for removing, the above medicine adding processing technology is capable of reducing generation of chemical sludge, influences of medicineadding on the ecological environment, and reducing sewage processing cost at the same time.
Description
technical field [0001] The invention relates to the field of sewage treatment, in particular to a control method and system for the regeneration and utilization of ceramic membrane sewage denitrification and phosphorus removal. Background technique [0002] At present, with the continuous growth of the population and the continuous improvement of people's living standards, the per capita discharge of domestic sewage continues to increase, coupled with the widespread use of detergents, the nitrogen and phosphorus content in urban sewage is high, and the nitrogen in the receiving water will be reduced after being discharged into the water body. , Phosphorus content increases, which in turn will lead to eutrophication of the water body, damage the water body environment, and affect the water supply quality. At the same time, the shortage of water resources also restricts the social and economic development. How to remove nitrogen, phosphorus and other nutrients in sewage at th...
