Heavy metal adsorbing granule containing ginkgo leaves and preparation method of heavy metal adsorbing granule

Abstract

The invention discloses a heavy metal adsorbing granule containing ginkgo leaves. The heavy metal adsorbing granule is characterized by being prepared from the following raw materials in parts by weight: 30-40 parts of ginkgo leaves, 5-10 parts of waste porcelain powder, 3-5 parts of zeolite powder, 1-2 parts of soyabean protein powder, 2-4 parts of kawo kawo fibers, 3-5 parts of light weight calcium carbonate, 0.1-0.2 part of potassium cocoyl glycinate, 0.1-0.2 part of sodium benzoate, 0.5-1 part of a citric acid, 0.1-0.2 part of glycine, and 5-10 parts of an adhering auxiliary material. The adsorbing granule disclosed by the invention is high in adsorption capacity, not only can effectively adsorb and remove heavy metal ions in a water body, but also has a definite effect of adsorbing and removing nitrogen and phosphorus organic compounds in the water body, is high in water purification capacity, is good in economical efficiency, and does not generate secondary pollution to the environment. Base material sources are rich, and base materials are natural and easy to obtain.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a ginkgo leaf heavy metal adsorption granule and a preparation method thereof. Background technique [0002] Due to the rapid development of industry, heavy metal pollution is becoming more and more serious. Among them, industries such as electronics, electroplating, tanning, and mineral processing produce a large amount of industrial wastewater containing heavy metal ions every year. The subsequent treatment of heavy metal wastewater has always been the focus of attention and research. . Heavy metals cannot be biodegraded in the environment, tend to be enriched in living organisms, can accumulate in the human body through the biological chain, destroy normal physiological metabolic activities, and even cause "three causes" (carcinogenic, teratogenic, and mutagenic) Substances are extremely harmful, so economical and effective methods are needed to remove various heavy metal ions ...

Problems solved by technology

[0003] Traditional heavy metal-polluted wastewater treatment methods include chemical precipitation, ion exchange, membrane separation, solvent extraction, and redox methods. They have their own advantages, but they all have limitations, mainly reflected in high cost and high energy consumption. , Difficult operation, easy to produce secondary pollution, etc., especially when dealing with low-content heavy metal polluted wastewater, the operating costs and raw material costs are relatively high
