Abstract

The invention discloses a method for treating heavy metal sewage, which is extracted by polymerizing ferrosilicon sulfate, polyacrylamide, aluminum tripolyphosphate, petroleum ether, octadecyl dimethyl, manganese sulfate, hydroxyethylidene diphosphonic acid and brown algae Compound sewage treatment agent formulated with alum, tertiary butyl hydroquinone, pyrrolidone, thiabendazole, and ethyl naphthol reacts with sewage by stirring, after ultrasonic treatment, the ion exchange column is eluted through the column, and the flocculant is stirred, flocculated and precipitated , the flocculation supernatant is passed through a column adsorption resin, filtered through a membrane filter, and sterilized to obtain discharge standard treated water. The method has high removal efficiency for heavy metals in sewage, simple and easy process, strong operability, no pollution to the environment, can meet the requirements of the industry, and has good application prospects.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a heavy metal sewage treatment method. Background technique [0002] Water is the source of life and the most precious resource in nature. The protection, utilization and treatment of water resources is one of the hottest topics in the world today. Therefore, international research on water quality and water treatment technology is developing rapidly, and pollution from industrial wastewater and domestic wastewater is also a major problem facing the country. . my country is one of the countries that lack water resources in the world. The development of water quality and water treatment technology has made great progress, and has made great contributions to environmental protection and water conservation. However, the current sewage treatment technology and development There is still a large gap between countries. At present, the domestic water treatment technology and ...
