Efficient heavy metal wastewater flocculating agent based on plant extracts and preparation method thereof

Abstract

The invention discloses an efficient heavy metal wastewater flocculating agent based on plant extracts and a preparation method thereof. The efficient heavy metal wastewater flocculating agent is prepared from the following raw materials in parts by weight: 2 to 5 parts of purslane extract, 1 to 4 parts of dandelion extract, 2 to 8 parts of dry lotus leaves, 5 to 10 parts of wheat straw, 10 to 15 parts of Selaginella tamariscina leaves, 1 to 4 parts of reed straw, 3 to 9 parts of hydroxyapatite, 2 to 6 parts of phosphate ore, 5 to 8 parts of oyster shell powder, 2 to 9 parts of trass volcanic ash, 7 to 10 parts of polylactic acid fiber, 5 to 12 parts of hydroxy acrylic resin, 5 to 9 parts of fatty alcohol-polyoxyethylene ether, 6 to 9 parts of Arabic gum, 3 to 9 parts of nano calcium sulfate, 5 to 10 parts of sodium diethylhexyl sulfosuccinate, 1 to 2 parts of sulfur, 1 to 4 parts of acraldehyde, 2 to 7 parts of magnesium silicate, 3 to 6 parts of gallotannic acid, 4 to 8 parts of a heat stabilizer, 2 to 5 parts of a coupling agent and 1 to 3 parts of a coagulant aid. The prepared wastewater flocculating agent is safe, stable and high in flocculation ability, metal ions can be effectively chelated, and the effect of wastewater treatment is reached. Simultaneously, the invention also discloses a corresponding preparation method.

Description

technical field [0001] The invention relates to the field of wastewater treatment agents, in particular to a high-efficiency heavy metal wastewater flocculant based on plant extracts and a preparation method thereof. Background technique [0002] my country is a country with a shortage of water resources, how to alleviate the shortage of water resources and pollution has become an urgent problem. At present, there are many methods such as physics, chemistry, biology, and comprehensive methods to deal with the pollution of water resources, but most of the physical methods have problems of poor treatment effect and unstable treatment rate; the cost of biological methods is too high to be popularized and used; how to find a A sewage treatment agent with excellent performance and good stability to improve the treatment effect of industrial sewage has become a technical problem to be solved at present. In particular, electroplating is one of the industries with serious pollution...

Problems solved by technology

At present, there are many methods such as physics, chemistry, biology, and comprehensive methods to deal with the pollution of water resources, but most of the physical methods have problems of poor treatment effect and unstable treatment rate; the cost of biological methods is too high to be popularized and used; how to find a A sewage treatment agent with excellent performance and good stability to improve the treatment effect of industrial sewage has become a technical problem that needs to be solved at present

In particular, electroplating is one of the industries with serious pollution. Electroplating wastewater is rich in metal ions, such as Cu2+, Ni2+, Cr3+, Zn2+, Pb2+, Ag+, Cd2+, etc. If it is not recycled, it will cause waste of resources and seriously threaten people's health. Physical Health and Quality of Life

At present, the most widely used electroplating wastewater treatment technology at home and abroad is still the chemical precipitation method, but the treatment efficiency is low, the amount of sediment is large, and it is easy to cause secondary pollution.
