Filler particles for aquaculture water quality improvement and tail water purification, preparation method thereof, and reactor containing same

Abstract

The invention discloses filler particles for improving the quality of aquaculture water and purifying tail water, and a preparation method of the filler particles. The filler particles are prepared through the following steps: mixing biomass with coal, iron-rich substances, a catalyst and an adhesive to obtain a mixture; performing granulation on the mixture; performing anaerobic carbonization; and performing microporous sintering to obtain the filler particles. Through the adoption of the filler particles, an eutrophied element, namely nitrogen, can be removed from a water body; especially, the rate of removing ammonia nitrogen and nitrite nitrogen, which are harmful to fish, is high; and besides, the filter particles have a permanent removing effect on phosphorus in the water body. The invention further discloses a reactor comprising the filler particles. Besides the filler particles, an aerator pipe is also arranged in the reactor, so that the oxygen dissolved in the water bodies can be rapidly increased, and fish faeces and feed residuals in settlings can be degraded; and besides, residual fish medicines and hormones can also be degraded, so that the quality of the aquaculture water is effectively improved, and the aquaculture tail water is purified.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to filler particles for aquaculture water quality improvement and tail water purification, a preparation method thereof and a reactor containing the same. Background technique [0002] China's aquaculture production accounts for 70% of the world's total, and the aquaculture water environment is the key point, not only related to the quality and safety of aquaculture products, economic benefits, but also to the national water environment. At present, the water sources for aquaculture come from rivers, lakes, sea water, etc., but most of them are seriously polluted. More than 60% of lakes in my country are in heavy eutrophication; according to the 2015 marine environmental quality report of Jiangsu Province, the water quality near the estuary flowing through Yancheng tidal flats is in the category V standard of surface water, and the non-ionic ammonia exceeds the standard r...
