Aquaculture water purifying agent

Abstract

The invention discloses an aquaculture water purifying agent, and relates to the technical field of aquaculture. The aquaculture water purifying agent is prepared from the following raw materials in percentage by mass : 20% to 30% of allophane, 10% to 20% of light shale powder, 8% to 10% of brucite fiber, 8% to 10% of diatomaceous earth, 8% to 10% of bentonite, 15% to 20% of coal-based activated carbon,10% to 20% of light calcium carbonate, 10% to 20% of polyaluminum chloride, 5% to 8% of thiobacillus denitrificans, 5% to 8% of bacillus licheniformis, 3% to 5% of bio-bacteria remover, 3% to 8%of corn flour, 10% to 15% of radix rehmanniae recen, 3% to 5% of flocculant, and 3% to 8% of coconut shell powder. According to the aquaculture water purifying agent provided by the invention, the allophane as a main component has the small particle size, strong adsorption capacity and is low in cost, and the prepared purifying agent is fast and effective in purification effect, high in treatmentefficiency, and small in process occupying area.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an aquaculture water purifier. Background technique [0002] According to the 2015 Environmental Statistical Annual Report released by the Ministry of Environmental Protection, the chemical oxygen demand and ammonia nitrogen discharged from agricultural sources accounted for 47.6% and 31.8% of the total amount of wastewater discharged nationwide in 2015, of which the chemical oxygen demand discharged from livestock and poultry farming industry Oxygen demand and ammonia nitrogen accounted for 95.3% and 78.3% of the total agricultural sources, respectively. From this analysis, the chemical oxygen demand and ammonia nitrogen emitted by the livestock and poultry industry have become the main sources of agricultural pollution sources. There have been a large number of research reports on the treatment process of livestock and poultry breeding sewage. Among them, the treatment of a...

There have been a large number of research reports on the treatment process of livestock and poultry breeding sewage. Among them, the treatment of anaerobic digested liquid after anaerobic digestion of livestock and poultry breeding sewage has traditionally used the oxidation pond process, which takes a long time and occupies a large area. Therefore, Finding a fast and effective treatment method is currently a research hotspot in the post-treatment of anaerobic digested liquid, and aquaculture water purifiers have become the research and development target of post-treated anaerobic digested liquid
