Abstract

The invention belongs to the technical field of sewage treating agents and particularly relates to a heavy metal sewage treating agent and a preparation method thereof. The heavy metal sewage treating agent is prepared from the following raw materials in parts by weight: 0.5-2 parts of amino trimethylene phosphonic acid, 1-5 parts of ethylene glycol tetraacetic acid, 10-20 parts of sodium polyacrylate, 5-15 parts of diethylene triaminepentaacetic acid pentasodium salt, 10-20 parts of polyaspartic acid, 20-30 parts of starch xanthate, 3-6 parts of graphene nanolayer / MnO2 compounds, 15-20 parts of crosslinked rectorite, 10-30 parts of polyaluminum chloride, 5-10 parts of chitosan-graphene composite and the balance of deionized water. The heavy metal sewage treating agent provided by the invention is high in purity, nontoxic, free of influence to operating staff and capable of ensuring no secondary pollution and other problems after water is treated.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a heavy metal sewage treatment agent and a preparation method thereof. Background technique [0002] my country is a country with a shortage of water resources. The per capita water resources are only 1 / 4 of the world's, and the distribution of water resources is seriously uneven. How to alleviate the problems of water scarcity and pollution has become an urgent problem. To solve the problem of water shortage, in addition to increasing income and reducing expenditure and comprehensive utilization, pollution control has gradually become one of the basic principles that my country must adhere to for a long time. [0003] At present, there are three main types of heavy metal wastewater treatment methods in the world: the first category is the method of removing heavy metal ions in wastewater through chemical reactions, including neutralization precipitation, sulfide precipi...
