Low-cost flocculating agent

Abstract

The invention discloses a low-cost flocculating agent. The low-cost flocculating agent comprises, by mass, 30-43 parts of a silicate solution, 10-35 parts of triethylamine, 8-10 parts of starch, 6-15 parts of carboxymethylcellulose sodium, 8-16 parts of anhydrous ethanol, 30-43 parts of ammonium persulfate, 30-43 parts of sodium carbonate, 30-43 parts of iron citrate, 3-10 parts of ethylenediamine, 15-25 parts of sulfuric acid, 20-35 parts of a sodium hydroxide solution, 30-45 parts of an iron salt agent solution, 3-5 parts of polyacrylamide, 15-25 parts of magnesium chloride, 9-18 parts of sodium oxide, 8-12 parts of acrylic acid, 9-15 parts of monohexadecyl maleate sodium salt and 30-50 parts of deionized water. The prepared water treatment flocculating agent has the advantages of increased viscosity, good stability, convenience for industrial production, safety, environmental protection, low cost, simple technology, high-efficiency flocculation effect, and realization of effective removal of colloids and suspension particles in water.

Description

technical field [0001] The present invention relates to a low-cost flocculant. Background technique [0002] In the chemical treatment of various waters including waste water, various flocculants are often used to gather and settle suspended solids and other impurities in the water. In the above-mentioned aggregation and precipitation process, in addition to the use of flocculants, aggregation aids are often used. Active silicone is one of these widely used aggregation aids. However, an important disadvantage of the above-mentioned active silicon enemies is that they cannot maintain their aggregation ability in long-term storage. In other words, active silicic acid, which is usually prepared by adding acid to silicic acid, becomes gelled in a short time, and the gelled silicic acid can no longer be used as a flocculant, so the active silicic acid The acid is only usable as an aggregation aid within about one day of preparation, which is a major disadvantage of using activ...

However, an important disadvantage of the above-mentioned active silicon enemy is that it cannot maintain its aggregation ability in long-term storage.

In other words, active silicic acid, which is usually prepared by adding acid to silicic acid, becomes gelled in a short time, and the gelled silicic acid can no longer be used as a flocculant, so the active silicic acid The acid is only usable as an aggregation aid for about a day after preparation, which is the main disadvantage of using activated silicic acid as an aggregation aid

It is also known that iron salts such as ferric sulfate and ferric chloride can also be used as flocculants, but when they are used alone, the aggregation efficiency of such iron salts is not high

Also, when slaked lime is used to adjust the pH, they form a large amount of waste waste sludge
