Abstract

The invention discloses a water treatment agent and belongs to the field of environment protection. The water treatment agent is synthesized by, by weight, 20-30 parts of diatomite, 20-30 parts of acrylamide, 4-6 parts of sodium hydroxide, 100 parts of water, acrylic acid, nano-silica, industrial dextrin, glycol and silane coupling agent, wherein the mass ratio of the acrylic acid to the acrylamide is 1:1.5-2, the mass ratio of the nano-silica to the acrylamide is 5-7:20-30, the mass ratio of the industrial dextrin to the acrylic acid is 1:5-8, and the mass ratio of the glycol to the acrylamide is 8-10:20-30. By the water treatment agent, the small-molecule solid in sewage can be effectively filtered and agglutinated on the surface of the water treatment agent.

Description

A kind of water treatment agent

Technical field

The present invention relates to environmental technology field, particularly to the technical field of water treatment agent.

Background technology

In modern industry, there is large amount of sewage, if the most treated direct discharge of these sewage, environment and human body can be made Become serious injury.

Summary of the invention

It is an object of the invention to provide and a kind of can effectively the solid impurity in sewage be filtered, and by its coagulation at table The water treatment agent in face.

Technical scheme is as follows: a kind of water treatment agent, and it is synthesized by following components: mass parts is the silicon of 20 ~ 30 Diatomaceous earth, mass parts is the acrylamide of 20 ~ 30, and mass parts is the sodium hydroxide of 4 ~ 6, and mass parts is the water of 100, with acrylamide Mass ratio is the acrylic acid of 1:1.5 ~ 2, is the nano silicon of 5 ~ 7:20 ~ 30 with the proportion of acylamide, with acrylic acid Mass ratio is the industrial dextrin of 1:5 ~ 8, with ethylene glycol and the silane coupler of the proportion of acylamide 8 ~ 10:20 ~ 30.

Preferably: the quality of described silane coupler is the 1% ~ 1.5% of described nano silicon quality.

The preferable following preparation method of this water treatment agent:

1) kieselguhr, acrylamide, sodium hydroxide is soluble in water, obtain the first solution after stirring, this solution is heated up To 80 ~ 90 DEG C, maintain the reflux under nitrogen atmosphere；

2) adding acrylic acid in the first solution, be uniformly mixed, constant temperature obtains the second solution after refluxing 4 ~ 6 hours；

3) the second solution is cooled to 60 ~ 70 DEG C, is added thereto to silane coupler, be stirring evenly and then adding into nanometer titanium dioxide Silicon, obtains the 3rd solution after constant temperature stirring 10 ~ 20min；

4) the 3rd solution is cooled to 30 ~ 40 DEG C, is added thereto to industrial dextrin, constant temperature backflow 30 under nitrogen atmosphere ~ 60min, obtains the 4th solution；

5) in the 4th solution, add ethylene glycol, after stirring, i.e. obtain described water treatment agent.

The water treatment agent of the present invention may filter that the little molecular solid impurity in sewage, and by its coagulation on surface, processes effect Rate is high, and dirt-removing power is strong.

Detailed description of the invention
