Abstract
The invention provides a novel scale inhibitor which is characterized by containing raw materials of 1-15 percent of ethylenediamine tetraacetic acid tetrasodium, 20-60 percent of citric acid, 1-15 percent of diethylene triaminepentaacetic acid pentasodium and the balance of water. According to the technical scheme, the condensation ratio of industrial circulating water can be remarkably improved and the draining frequency of the sewage is reduced. In addition, the medicament can be simply synthesized and has low cost.
Description
Technical field
The invention belongs to water-treatment technology field, particularly relate to a kind of circulating water treatment water quality stabilizer.
Background technology
At present industrial cycle water treatment medicament all is to be main with phosphorous medicament, and this type medicament is mature on the whole through the development of decades technically, and treatment effect can arrive the standard of country or relevant industries.But they also have many great disadvantages: phosphorous height, environment has been caused considerable damage, and increased the cost of waste water treatment, the circulation draining is difficult to recycle; The consumption of anti-incrustation corrosion inhibitor and sterilant is big simultaneously, and the cost of water treatment is high.Therefore the exploitation of low-phosphorous or without phosphorus water treatment agent receives people's attention.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides the concentration rate that a kind of cost is low, can improve industrial circulating water, reduce the novel Scale inhibitors of sewage discharge frequency.
Particularly; The invention provides a kind of novel Scale inhibitors; Contain raw material tetrasodium ethylenediamine tetraacetate, Hydrocerol A and diethylene triamine pentacetic acid (DTPA) five sodium; With the Scale inhibitors gross weight is benchmark, wherein tetrasodium ethylenediamine tetraacetate 1-15%, Hydrocerol A 20-60%, diethylene triamine pentacetic acid (DTPA) five sodium 1-15%, and surplus is a water.
Further preferably, raw material weight per-cent is tetrasodium ethylenediamine tetraacetate 1-5%, Hydrocerol A 25-40%, diethylene triamine pentacetic acid (DTPA) five sodium 1-5%, and surplus is a water.
Novel Scale inhibitors provided by the invention prepares in the process being spaced apart more than five minutes of adding between every kind of raw material.
Advantage of the present invention and characteristics are: use the present technique scheme can obviously improve the concentration rate of industrial circulating water, reduce the sewage emissions frequency, and this medicament is synthetic simple, cost is low.
