Problems solved by technology

[0004] High-concentration industrial wastewater is not only different from domestic sewage, but also different from general industrial wastewater. It often contains a variety of toxic and harmful refractory organic matter, heavy metal ions and ammonia nitrogen and other pollutants. Due to the single flocculation component, the treatment effect of these high-concentration wastewater is not ideal, especially for the removal of dissolved pollutants in water.
Therefore, for high-concentration wastewater, there is still a lack of a flocculant with broad spectrum, high efficiency, good stability, strong specificity, excellent flocculation performance, and moderate cost performance.

Abstract

The invention discloses a wastewater treating flocculant and a preparation method thereof and belongs to the field of water treating agents. The wastewater treating flocculant is prepared from, by weight, 4-10 parts of sodium ethylenesulfonate, 4-10 parts of polymeric phosphate-ferric chloride, 3-9 parts of poly-aluminum chloride, 4-10 parts of copolymer of maleic and acrylic acid, 3-9 parts of magnesium sulfate, 6-12 parts of sodium polyacrylate, 4-10 parts of sodium styrenesulfonate monomer, 4-10 parts of alginic acid, 4-12 parts of ferric citrate, 4-10 parts of sodium lignin sulfonate and 150-200 parts of water. The wastewater treating flocculant has the advantages of short flocculent precipitating time, good effect, low cost and capabilities of improving active emulsifying power of water molecules, degrading harmful substances and heavy metals in water, and treating high-concentration high-turbidity wastewater and non-biodegradable wastewater effectively to enable treated water to be recycled.

Description

Technical field [0001] The invention relates to a flocculant for treating wastewater and a preparation method thereof, belonging to the field of water treatment agents. Background technique [0002] Flocculation is one of the most commonly used key links in wastewater treatment processes. It largely affects the operating conditions of subsequent processes, the final effluent quality and costs, so it has become an important scientific and technological research and development field in environmental engineering. High-efficiency flocculation technology system should be closely combined with excellent flocculant, reactor and self-controlled dosing, among which flocculant plays a core role. The key to flocculation treatment technology is to choose a suitable flocculant. [0003] There are many classification methods for flocculants. According to their composition, they can generally be divided into inorganic flocculants, organic flocculants, and natural flocculants (such as biological...
