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 shortage of water resources and pollution has become an urgent problem. In order to solve the problem of water shortage, in addition to increasing sources of income, reducing expenditure, and comprehensive utilization, pollution control has gradually become one of the basic principles that our country must adhere to for a long time.

[0003] At present, there are three main types of heavy metal wastewater treatment methods in various countries in the world: the first type is the method of removing heavy metal ions in wastewater through chemical reactions, including neutrali...
