Abstract

The invention discloses a heavy metal precipitator and a preparation method therefor and application thereof. The heavy metal precipitator comprises sodium hydroxide, nano calcium oxide, modified potassium hydroxide, dithiocarboxylic acid and nano sodium carbonate, wherein relative to 100 parts of sodium hydroxide, the content of nano calcium oxide is 1-10 parts by weight, the content of modified potassium hydroxide is 20-30 parts by weight, the content of dithiocarboxylic acid is 1-10 parts by weight and the content of nano sodium carbonate is 1-10 parts by weight. The heavy metal precipitator prepared by the method in actual use in heavy metal containing water can be used for effectively precipitating heavy metals in sewage so as to effectively improving the water quality of sewage, so that the pollution on a water body is greatly reduced.

Description

technical field [0001] The invention relates to the field of water treatment materials, in particular to a heavy metal precipitant and its preparation method and application. Background technique [0002] In daily production and life, water plays an extremely important role as a human necessity, but with the continuous improvement of living standards and technology, the pollution of water quality in today's society is extremely serious, and in many cases, artificial The sewage produced will be treated, but directly discharged into nature, thus bringing great pollution to nature. [0003] Therefore, it is an urgent problem to be solved in the present invention to improve a heavy metal precipitant and its preparation method that can effectively precipitate heavy metals in sewage, better treat water quality, and achieve the purpose of effectively protecting water sources and the like. Contents of the invention [0004] In view of the above-mentioned prior art, the purpose of...
