Abstract

The invention relates to a modified adsorbing material for treating wastewater. The modified adsorbing material is prepared from the following components: 50-60 parts of modified polystyrene resin, 3-6 parts of biological flora, 0.5-1 part of flora protective agent, 10-15 parts of flocculating agent and 20-30 parts of inorganic filler. The modified polystyrene resin designed by the invention has the characteristic of large specific surface area of macroporous resin, and has relatively strong adsorption capacity, and meanwhile, the polymer trunk is degradable and is easy to hydrolyze into small molecules in a water body, so that secondary pollution to the environment caused by macromolecular polymer residues is avoided; biological florae are added based on the modified macroporous adsorption resin, the purpose of purifying water is achieved by using a small amount of biological florae, and meanwhile due to the small amount, eutrophication of the water body cannot be caused; other additives are matched for use, so that pollutants in the aquatic wastewater can be better treated, the improvement of the water environment is promoted, and the natural balance of the water environment is realized.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a modified adsorption material for treating waste water. Background technique [0002] my country is rich in fresh water resources, and the amount of aquaculture is in the forefront of the world. However, most domestic aquaculture uses closed waters such as ponds and reservoirs. The self-purification ability of the water body is not as good as that of living water sources. In addition, the application of a large amount of feed leads to eutrophication of the aquaculture water. The application of fungicides and disinfectants and the accumulation of dead animals and plants directly lead to the accumulation of organic matter, nitrogen and phosphorus in the water body. Great harm. [0003] At present, the general sewage treatment process is usually divided into three categories, namely physical method, chemical method and biological method. Using a single method is often difficult to ac...
