Abstract

The invention discloses a composite component for promoting sewage flocculation, which comprises the following raw materials in parts by weight: montmorillonite, 20-30 parts; calcite, 15-25 parts; attapulgite, 30-40 parts; wollastonite , 10-20 parts; borax, 10-20 parts; heavy calcium carbonate, 5-15 parts; talc powder, 5-15 parts; the mixture of mica powder and coal gangue, 6-8 parts; The ratio of parts by weight of gangue is 5-7:1. The composite component of the invention can well play the role of flocculation, effectively remove organic matter and heavy metal ions in the water body, reduce sewage turbidity, and improve sewage treatment efficiency. The preparation method provided by the invention is simple and practical, easy for large-scale preparation, and suitable for popularization.

Description

technical field [0001] The invention belongs to the field of environmental protection and relates to sewage treatment, in particular to a composite component for promoting sewage flocculation. Background technique [0002] With the rapid development of my country's economy, people's living standards have been greatly improved, but accompanied by increasingly serious environmental pollution problems. Monitoring data show that 13 of the 15 major urban river sections that the 7 major rivers flow through are seriously polluted, the quality of surface water and groundwater in many cities has deteriorated, and drinking water sources are threatened by pollution; It has reached 45 billion tons, basically discharged directly without treatment, causing serious pollution of my country's water resources, which has reached the level that must be treated. my country has taken environmental protection as its basic national policy, and environmental protection has increasingly become an imp...
