Wastewater composite adsorption-flocculation material

Abstract

The invention discloses a wastewater composite adsorption-flocculation material. The wastewater composite adsorption-flocculation material comprises adsorbent and flocculant, and is characterized in that the adsorbent comprises, by weight, 20-40 parts of bagasse cellulose xanthate, 15-25 parts of hollow bric particles, 5-15 parts of bagasse lignin magnesium sulfonate, 5-10 parts of expanded vermiculite particles, and 5-10 parts of modified attapulgite; the flocculant comprises, by weight, 20-30 parts of PSFC, 10-20 parts of hydrophobic modified lignin fibers, 20-40 parts of nonionic polyacrylamide, 2-10 parts of polyepichlorohydrin, 10-17 parts of polyhydroxy aluminum chloride silicon, and 3-8 parts of activated carbon powder. With reasonable formula, wastewater treatment process is simplified, wastewater treatment effect and efficiency are upgraded, and the wastewater composite adsorption-flocculation material is used for treatment of high-turbidity and high-organic content wastewater such as domestic and industrial wastewater.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment materials, in particular to a composite adsorption-flocculation treatment material for wastewater treatment. Background technique [0002] Although 70.8% of the earth is covered by water, fresh water resources are extremely limited. What we can really use are rivers, lakes and groundwater, which only account for 0.26% of the total water on the earth, and the distribution is uneven. After the 1950s, the global population grew rapidly and industries developed rapidly, accompanied by the rapid deterioration of the global water resources situation, and the "water crisis" became increasingly serious. On the one hand, the human demand for water resources is increasing at an alarming rate; on the other hand, the increasingly serious water pollution erodes a large amount of water resources available for consumption. The increasing water pollution has attracted more and more people's attentio...

Problems solved by technology

[0003] According to investigations, as many as half of the treatment plants used for sewage treatment are currently out of business, and the operating efficiency of the treatment plants in operation is low. This is due to the low environmental awareness of the inherent producers, but the more important reason is The reason is that the sewage treatment process is complicated, the treatment cost is high, and the flocculant used for sewage with different pollutants has poor flocculation effect, resulting in low sewage treatment efficiency, etc., and there is no suitable solution for the follow-up treatment of large amounts of refractory flocculation materials. These reasons are also the main bottlenecks restricting my country's wastewater treatment
