Abstract

The invention discloses a heavy metal wastewater treatment agent, which includes olea europaea pomace, olea europaea sawdust, nitrohumic acid resin, dithiocarboxylated aminomethyl polyacrylamide, biochar, pyrrolidine dithiocarbamate chelated cellulose, starch xanthate, sodium dodecyl sulfonate, a cross-linking agent, sulfonated sulphur heterocarbon, 717 anion exchange resin, modified sericin, polyaspartic acid, beta-cyclodextrin, thiocarbazide, an accelerant, poly(diallylammonium chloride-acrylamide)yl sodium dithiocarbamate. Complexing, precipitation, coagulation, adsorption and other ways are adopted for synergistic coupling integrated treatment of heavy metal wastewater, the treatment agent has the characteristics of coarse flocculation, fast precipitation and strong trapping capacity,and can treat Cu<2+>, Cd<2+>, Hg<2+>, Pb<2+>, Mn<2+>, Ni<2+>, Zn<2+>, Cr<3+> and various heavy metals in wastewater, and also can remove part of COD ammonia nitrogen, phosphorus and Cr<6+>.

Description

technical field [0001] The invention relates to the field of waste water treatment, in particular to a heavy metal waste water treatment agent. Background technique [0002] Heavy metal wastewater mainly comes from mining, non-ferrous metal smelting, machining, electroplating, etc. Most of them contain heavy metal elements such as lead, zinc, chromium, arsenic, cadmium, nickel, copper, etc., which seriously pollute the environment. In addition, due to the high solubility of heavy metal ions in water, they are easily absorbed by organisms, thus enter the food chain, and eventually accumulate in the human body. When accumulated to a certain extent, they will cause great harm to human health. Existing technologies are generally divided into chemical methods, physical chemical methods and biological methods. Among them, the chemical method has a simple process and is easy to operate, but there are many problems such as high metal concentration in the effluent, large amount of w...
