Abstract

The invention discloses composite algicide consisting of gemini quaternary ammonium cation surfactant and clay solution and an algae removal method. The gemini quaternary ammonium cation surfactant has a structural formula in which R is C9-C20 alkyl, n is an integer from 2-10, and X is Br or Cl. The composite algicide not only has obvious algae removal effect, the dosage of the algicide is small and the algae removal efficiency is high. Meanwhile, the algae removal method is simple in operation, with the algae removal effect improved in aspects of dosage of the algicide and the algae removal time. Therefore, the algae removal method is more convenient and practical than the prior art.

Description

Technical field: [0001] The invention relates to an algaecide and an algae removal method, in particular to a compound algae removal agent composed of gemini surfactants and clay and an algae removal method. Background technique: [0002] In recent years, due to the massive discharge of industrial wastewater, domestic sewage, and agricultural wastewater into freshwater lakes and reservoirs, a large amount of nutrients such as nitrogen and phosphorus in the waters have been enriched, and the problem of eutrophication in the waters has become increasingly serious. Among them, the most prominent problem of eutrophication is the algal bloom. According to statistics, 60% of the lakes in our country are in a eutrophic state, and algae blooms also exist. When a water bloom occurs, a large number of algae will consume too much oxygen in the water, causing fish and plankton to die due to lack of oxygen. At the same time, the death of the algae will give off a foul smell, and some c...
