Abstract

The invention discloses composite microbial sustained release tablets for water treatment and a preparation method thereof. The preparation method comprises the following steps: preparing composite calcium peroxide particles, preparing composite microbial coating particles, and preparing the composite microbial sustained release tablets. The composite microbial sustained release tablets are prepared by adopting modes of coating, providing an oxygen source, preparing tablets, performing sustained release and the like. After the technology is adopted, the strain reservation time can be prolonged, the content of dissolved oxygen in a water body is improved, the strain survival rate is improved, microorganism reproduction and growth can be promoted, the using cost is saved, and the effect of purifying and improving the water quality is achieved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a composite microbial slow-release tablet for water treatment and a preparation method thereof. Background technique [0002] At present, various surface water, sewage, landscape water and aquaculture water environments are generally polluted to varying degrees. So far, drugs are mainly used to improve water quality, mainly including zeolite, calcium peroxide, bleaching powder, etc., which have great impact on reducing ammonia nitrogen and The content of hydrogen sulfide and the content of dissolved oxygen in pool water have a certain effect, but these drugs will destroy the normal ecological environment of the breeding environment and reduce the adaptability of aquatic animals to the external environment. At the same time, in the case of serious water pollution, the drugs can only Play a certain effect in the short term, so these drugs can only be used as emergency medic...
