Abstract

The invention discloses a preparation method of a phosphorus removal material, which is characterized by comprising the steps of 1) putting a graphite powder raw material, grinding balls and a ball milling medium into a ball milling tank according to a mass ratio of 1: (10-20): (4-6), carrying out ball milling on ball milling equipment for 24 hours at a rotating speed of 400-600r/min, then taking out, drying, and sieving with a 200-mesh sieve to obtain graphite powder; 2) dissolving the obtained graphite powder in a copper sulfate solution according to a solid-to-liquid ratio of 1: (5-10), carrying out ultrasonic treatment at 80-100KHz for 4-6 hours, then filtering and washing, carrying out high-temperature calcination on the obtained solid at the temperature of 800-1000 DEG C for 1-3 hours, and cooling to room temperature after the calcination is ended so as to obtain a solid product; and 3) mixing the obtained solid product with polystyrene and polyvinyl chloride according to a mass ratio of 1: (0.5-1): (0.5-1), carrying out a cross-linking reaction under the action of a catalyst, drying the product after the reaction is finished, and carrying out extrusion molding in a twin-screw extruder to obtain the phosphorus removal material. The material has an obvious removal effect on phosphorus and other pollutants in sewage.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a phosphorus removal material and a preparation method thereof. Background technique [0002] With the development of industry and agriculture and the growth of population, the production and consumption of chemical fertilizers, pesticides, and phosphorus-containing detergents have increased rapidly. Water eutrophication caused by water pollution has become increasingly serious. Water eutrophication has endangered agriculture, fishery, and tourism. It also poses a huge threat to drinking water sanitation and food safety. The main nutrients that cause water eutrophication include organic carbon, nitrogen, phosphorus, potassium, etc. Organic carbon in sewage can be basically removed after general biological treatment, and the content of other components other than nitrogen and phosphorus is relatively The demand in the process is extremely low and will not be ...
