Aquaculture water quality improver and preparation method thereof

Abstract

The invention provides an aquaculture water quality improver, which is prepared from the following components in parts by weight: 8-15 parts of oyster shell powder, 2-5 parts of activated carbon, 2-5 parts of kieselguhr, 5-10 parts of bentonite, 5-10 parts of kaolin, 1-3 parts of zeolite, 0.01-0.1 part of dodecyl dimethyl betaine, 0.01-0.1 part of myristic acid and 3-7 parts of activated aluminum oxide. The aquaculture water quality improver is a compound water quality improver mainly for adsorbing heavy metals, and has good adsorption ability for several main pollutants in a water body, thus being used for improving aquaculture water quality. The water quality improver is spherical, is rough in surface, and has more pore structures; due to the enlarged specific surface area, the water quality improver is beneficial to absorption of various pollutants. The aquaculture water quality improver is low in cost, simple in preparation method and good in effect; furthermore, when in use, the aquaculture water quality improver does not cause secondary pollution, thus having higher exploitability.

Description

technical field

[0001] The invention relates to an improver and a preparation method thereof, in particular to an aquaculture water quality improver and a preparation method thereof. Background technique

[0002] In recent years, the aquaculture industry has developed very rapidly. However, a large amount of industrial wastewater, agricultural wastewater, and domestic sewage rich in heavy metals, nitrogen, and phosphorus have been discharged into rivers, rivers, and lakes, which has seriously deteriorated the ecological environment of the water area and made the aquaculture water environment worse. The problem of pollution has become increasingly prominent. The monitoring of most inland fishery waters by the National Fishery Ecological Environment Monitoring Network shows that the ecological environment of China's fishery waters is generally stable, and local pollution is serious. The main pollutants are nitrogen, phosphorus, petroleum and copper. The deterioration of the a...
