Abstract

The invention discloses an efficient phosphorus removal agent and a preparation method thereof. The efficient phosphorus removal agent is prepared from, by weight, 4-8 parts of manganolite, 5-10 parts of magnetite, 3-5 parts of carbon residues, 3-5 parts of a binder, 3-5 parts of sodium sulfite, 10-30 parts of ferric trichloride, 0.5-0.7 part of cobalt chloride, 80-100 parts of polymeric aluminum, 2-4 parts of sodium hypochlorite, 6-8 parts of polymethyl diallyl ammonium chloride, 0.02-0.06 part of nonionic polyacrylamide and 180-220 parts of water. The binder is one or two of cement, sodium borate and plaster. The treatment effect is obvious, the treatment input is small, and the treatment cost is low; environmental protection can be achieved, waste recycling is achieved, the phosphorus removal efficiency is improved by 40% or above compared with liquid ferric trichloride, the application prospect is good, the requirements for environmental friendliness and circular economy can be met, and good social and economic benefits are obtained.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a high-efficiency phosphorus removal agent and a preparation method thereof. Background technique [0002] Phosphorus is one of the main elements that sustain life in the earth system, and it is also an essential element that constitutes living organisms and participates in metabolic processes. The abundance of elements and the quality of the phosphorus environment will directly affect the growth and development of all living things, including humans. In recent years, water eutrophication has become a worldwide concern. Generally speaking, when the total phosphorus concentration in water exceeds 20 mg / L, it can be considered that water is eutrophic. The main elements that cause water eutrophication are phosphorus and nitrogen. Phosphorus has a special effect on water eutrophication. Sewage containing a large amount of nutrients flows into closed waters such as lakes, w...
