Abstract

The invention discloses a wastewater treating agent for wastewater containing heavy metal. The wastewater treating agent is prepared from, by weight, 10-18 parts of nano-titania, 10-21 parts of dendrobium leaves, 45-73 parts of attapulgite, 10-17 parts of hydrochloric acid, 8-15 parts of ferric trichloride, 5-21 parts of polyacrylamide, 5-13 parts of dimethyl diallyl ammonium chloride, 1-5 parts of activated carbon powder, 3-14 parts of ethylenediamine tetraacetic acid disodium salt, 4-8 parts of tert-butylamine, 3-8 parts of hydroxymethyl starch, 1-5 parts of sodium silicate, 2-7 parts of sodium hydrosulfite, 4-16 parts of sodium hydroxide and 16-34 parts of water. The invention further discloses a preparing method of the wastewater treating agent. According to the prepared wastewater treating agent, the preparing process is simple, the raw material cost is low, and the raw material source is wide; the agent contains various active groups, the active groups and heavy metal can be subjected to a complexation reaction, a chelation reaction, an adsorption reaction, an exchange reaction and the like, and therefore heavy metal ions in wastewater can be removed. Thus, wastewater discharge can reach the standard, and remarkable economic benefits can be achieved.

Description

technical field [0001] The invention relates to a treatment agent, in particular to a sewage treatment agent for wastewater containing heavy metals. Background technique [0002] With the further improvement of pollution reduction requirements in the national "Twelfth Five-Year Plan", many sewage treatment plants across the country are facing the urgent task of upgrading and upgrading. At present, the influent of urban sewage treatment plants mostly contains industrial wastewater, which contains a large amount of heavy metals. Heavy metal wastewater refers to the wastewater containing heavy metals discharged from industrial production processes such as mining, machinery manufacturing, chemical industry, electronics, and instrumentation. Heavy metal (such as cadmium, nickel, mercury, zinc, etc.) wastewater is one of the most serious environmental pollution and one of the most harmful industrial wastewater to humans, and its water quality and quantity are related to the produc...
