Abstract

The invention provides a spunlace nonwoven sewage treatment additive which comprises five components including 22 materials, wherein the component I comprises sodium sulfate, TX-10, sulfonate, ammonium triacetate, peregal and water; the component II comprises sodium hydroxide, sodium phosphate, sodium citrate, tartaric acid and water; the component III comprises polyacrylic acid, isopropyl alcohol, benzotriazole, zinc sulfate, sodium polyacrylate and water; the component IV comprises aluminum sulfate, polyaluminum chloride, xanthan gum, carboxymethyl chitosan, acetic acid and water; the component V comprises dichloroisocyan, potassium ferrate, alum and water. By adopting the spunlace nonwoven sewage treatment additive provided by the invention, the needle plate blockage can be reduced in a nonwoven production process, the rust stain of the needle plate is prevented, the discharge times of the circulating water is reduced, and the unit production is obviously increased; moreover, little environmental pollution is caused, and the production technology is simple and feasible; the spunlace nonwoven sewage treatment additive is nontoxic and harmless to a human body and suitable for the spunlace nonwoven circulating water in different water qualities and different air temperature environments.

Description

technical field [0001] The invention relates to a sewage treatment additive, in particular to a spunlace non-woven sewage treatment additive. Background technique [0002] The spunlace process consumes a lot of water. In order to save water and reduce production costs, about 95% of the water must be recycled after water treatment. When the content of suspended solids is high, the service life of filter bags and filter elements will be shortened. Organic matter in dissolved or colloidal dispersion tends to turbid water and produce color. These substances are easy to deposit on the wall of the spray hole and adhere to the fiber, thus affecting the final whiteness of the product. The sludge formed by microorganisms will quickly block the water spray hole after being transported by the high-pressure water pump, causing the pressure of the water jet head to rise suddenly, causing parking in severe cases, and the inorganic salts dissolved in the water, whether it is anion or cat...
