Water purifying agent and preparation method thereof

Abstract

The invention belongs to the technical field of sewage treatment and particularly relates to a water purifying agent and a preparation method thereof. The water purifying agent comprises Potamogeton crispus L. extract, wood vinegar, activated carbon and water. The preparation method includes: measuring out the crispus L. extract, the wood vinegar, the activated carbon and the water according to the proportion, placing into a stirrer, and evenly stirring to obtain the water purifying agent. The water purifying agent and the preparation method thereof have the advantages that the raw materials of the water purifying agent are raw materials which do not bring impurities after water treatment and can be removed by direct filtration, the wood vinegar is volatile and low in influence on subsequent procedures, and the color of the wood vinegar can be absorbed by the activated carbon.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a water purifying agent and a preparation method thereof. Background technique [0002] With the continuous and rapid development of my country's national economy, the situation of environmental protection is becoming more and more severe. In particular, although my country's total fresh water resources account for 6% of the world's total, the per capita water resources are only 2,300 cubic meters, which is the world's average. In addition to water shortage, the water pollution problem is also very serious. At present, 44% of my country's water quality is inferior to the fifth category, and more than 80% of the surface water and groundwater are polluted due to the wanton discharge of industrial wastewater. [0003] As one of the most precious resources of human beings, water resources are more and more concerned by the world. At present, water purifiers are di...

In particular, although my country's total fresh water resources account for 6% of the world's total, the per capita water resources are only 2,300 cubic meters, which is the world's average. In addition to water shortage, the water pollution problem is also very serious. At present, my country's water quality is as high as 44%, and due to the wanton discharge of industrial wastewater, more than 80% of the surface water and groundwater are polluted.

[0003] As one of the most precious resources of human beings, water resources are more and more concerned by the world. At present, water purifiers are divided into two types: physical adsorption and chemical adsorption. Physical adsorp
