Problems solved by technology

[0003] Traditional water treatment agents include coagulants / flocculants, bactericides, scale inhibitors, etc., but they often have a single function, and there are many problems such as a wide variety, large dosage, complicated equipment, and cumbersome operations. There may be mutual inhibition between them, reducing the efficiency of water treatment

Abstract

The invention discloses an efficient water purifying agent and a preparation method thereof. The efficient water purifying agent comprises the following components in parts by weight: 60-80 parts of attapulgite composite active particles, 30-40 parts of hyperbranched polyethyleneimine grafted psyllium seed hull fiber, 5-10 parts of pentosan polymercaptan, 5-10 parts of polyaluminum ferric chlorideand 2-4 parts of an oxidant. The efficient water purifying agent disclosed by the invention has the effects of adsorption, flocculation, oxygenolysis, sterilization and the like; the content of harmful pollutants including suspended particles, bacteria, heavy metals, organic chemical pollutants, pigments, grease and the like in a water body can be rapidly and efficiently reduced; the sewage treatment agent is remarkable in sewage treatment effect, stable in property, free of secondary pollution after treatment and low in treatment cost, treated water can reach the discharge standard, and thewater purifying agent is suitable for sewage treatment in the fields of oily wastewater, printing and dyeing wastewater, papermaking sewage, municipal sewage and the like.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a high-efficiency water purifier and a preparation method thereof. Background technique [0002] Water treatment has always been one of the most important issues in the world. Globally, water consumption is increasing rapidly everywhere. At the same time, the problem of water pollution has become increasingly serious, and serious contradictions between supply and demand of water resources have emerged in many regions and countries. Therefore, how to improve the sewage treatment capacity so that it can be used here is extremely important. At present, the main sources of water pollution in the world mainly include industrial pollution, agricultural pollution and domestic sewage. In recent years, the discharge of industrial wastewater and urban domestic wastewater in my country is about 57.2 billion tons, of which the discharge standard rate of industrial wastewater is a...
