Abstract

The invention belongs to the field of sewage treatment and in particular relates to a preparation method and technology of an efficient phosphorus removal and denitrification biological material. Thephosphorus removal and denitrification biological material is prepared from the following raw materials in parts by weight: 1 to 15 parts of a biocompatible high polymer, 0.25 to 4 parts of a reinforcing agent, 2 to 50 parts of a bioactive substance and 0.2 to 20 parts of a curing agent. The phosphorus removal and denitrification biological material provided by the invention can be used for efficiently removing pollutants including nitrogen, phosphorus, organic matters and the like in sewage and the removal efficiency on total nitrogen, total phosphorus and COD (Chemical Oxygen Demand) can reach 70 percent, 85 percent and 60 percent or more respectively; TP (Total Phosphorus) can be reduced to 0.2ppm or lower from 1ppm or 10ppm. The material provided by the invention can be used for removing nutrient substances including the phosphorus, the nitrogen and the like in a simple, efficient and energy-saving manner, sludge is not generated and the operation is simple. Complicated removal flows including an anaerobic-aerobic process and the like in a traditional activated sludge method are replaced.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a preparation method and technology of an efficient phosphorus and nitrogen removal biological material. Background technique [0002] my country's water environment is seriously polluted, and rivers and lakes are generally polluted. For example, 75% of lakes have experienced eutrophication to varying degrees; 90% of urban waters are seriously polluted, which further aggravates the shortage of water resources and has great impact on the improvement of residents' lives and economic sustainability. The implementation of the development strategy has brought serious negative effects. [0003] In view of the current severe form of environmental pollution, my country plans to invest one trillion yuan to purify the environment during the "13th Five-Year Plan" period. Among them, the urban sewage treatment rate will not be lower than 90% by 2020. On the other hand, the country...
