Abstract

The invention discloses a silver sewage treating agent and a preparation method thereof. The silver sewage treating agent comprises, by weight part, 20-30 parts of modified saline-alkali soil, 10-18 parts of an auxiliary agent, 2-6 parts of cinnamaldehyde, and 0.1-0.2 part of sodium carbonate. The physicochemical indexes of the silver sewage treating agent can reach a GB18918-2002 standard, and the contents of COD, BOD, SS and silver ions can be effectively reduced. The silver sewage treating agent is simple in treating technology, less in consumption, good in treating effect, stable in performance and good in quality of discharged water. The cost for sewage treatment is reduced, and the silver sewage treating agent has huge economic and social benefit.

Description

technical field [0001] The invention relates to the technical field of a sewage treatment agent, in particular to a silver sewage treatment agent and a preparation method thereof. Background technique [0002] Heavy metal wastewater mainly comes from mine pit drainage, ore dressing plant tailings drainage, waste rock field leaching water, non-ferrous metal smelting plant dust removal drainage, non-ferrous metal processing plant pickling water, electroplating plant plated parts washing water, iron and steel plant pickling drainage, and electrolysis , pesticides, pharmaceuticals, paints, pigments and other industries. At present, there are various methods such as physics, chemistry, and biology to deal with the pollution of silver sewage treatment agents, but most of the physical methods have problems of poor treatment effect and unstable treatment rate; the cost of biological methods is too high to be popularized and used; more Chemical methods are used to treat sewage, but ...
