Goldfish and koi pond culture wastewater treatment agent

Abstract

A goldfish and koi pond culture wastewater treatment agent comprises the following components in parts by weight: 30-50 parts of diatomite, 12-20 parts of activated carbon, 16-24 parts of medical stone, 3-6 parts of lime, 1-2 parts of solid aluminum sulfate, 4-10 parts of a microbial inoculum, 1-3 parts of pectin and 10-14 parts of brown sugar. The wastewater treatment agent is low in manufacturing cost and simple and convenient to use; and the content of harmful substances and impurities in the treated water can be greatly reduced, so that the treated water can be continuously used for pond cultivation or irrigation of farmlands, and is suitable for popularization to a large number of farmers and farms.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a goldfish and koi pond culture wastewater treatment agent. Background technique [0002] At present, most of the large-scale farming of goldfish and koi in my country adopts pond farming. The aquaculture wastewater in this traditional farming method contains a large amount of fish feces, feed residues, granular impurities, dissolved metabolic waste, and dissolved nutrients. , antimicrobial agents and other residual drugs, most of this wastewater is simply filtered or directly discharged to ditches, rivers, nearby farmland, etc., which will cause problems such as eutrophication or even water quality deterioration in the water body, and it will also cause problems for crops in the farmland. Negative Effects. At present, there are few types of aquaculture wastewater treatment agents on the market, and most of them are made of chemical raw materials. The treatment effect is not good and it...

Problems solved by technology

[0002] At present, most of the large-scale farming of goldfish and koi in my country adopts pond farming. The aquaculture wastewater in this traditional farming method contains a large amount of fish feces, feed residues, granular impurities, dissolved metabolic waste, and dissolved nutrients. , antimicrobial agents, and other residual drugs. Most of this wastewater is simply filtered or directly discharged to ditches, rivers, and nearby farmland. Negative Effects

There are few types of aquaculture wastewater treatment agents on the market, and most of them are made of chemical raw materials. The treatment effect is not good and it is easy to cause secondary pollution to the water body. The treated water is not suitable for reuse.
