Problems solved by technology

[0004] Microbial cells used to purify aquaculture water are usually directly sprayed and put in, but such products do not protect the microbial cells, and the water flow will directly disperse the microbial cells, resulting in the random growth of the microbial cells on the filter material or water bodies, but cannot be colonized in a specific location, the effect is not obvious
And with the aging of microbial cells, the filter system will fail
In addition, the nutrients added to the products of the prior art are not fully protected or even completely exposed. When the product is in use, harmful bacteria such as E. Nutrients were robbed and utilized before, which promoted the reproduction of harmful microorganisms, and the carriers added in microbial preparations such as light calcium carbonate, zeolite powder, ceramsite, bentonite, diatomaceous earth, porous clay, porous volcanic rock, zeolite, etc. Unable to recycle, causing secondary pollution of water bodies

Abstract

The invention discloses a microorganic water-purifying slow release device, a preparation method and application thereof. The microorganic water-purifying slow release device comprises a protecting shell, a protective agent, a microbial flora powder and a multiplication accelerant; the protective agent, the microbial flora powder and the multiplication accelerant are contained in the protecting shell; the microbial flora powder and the multiplication accelerant are embedded in a timing slow-release layer. The microorganic water-purifying slow release device provided by the invention can maintain higher level for a long time and can keep ammonia nitrogen, nitrite and nitrate concentration at lower state, and the microorganic water-purifying slow release device need not be put in for the second time after being put in for a long period of time, so that a great convenience in use can be brought.

Description

technical field [0001] The invention relates to a microbial water purification slow-release device, a preparation method and application thereof. Background technique [0002] Traditional aquaculture is dominated by pond aquaculture. Due to the increasing shortage of water resources and land resources, pond aquaculture has low breeding density, poor economic benefits, and increasing costs. Recirculating aquaculture with filters is an inevitable trend of aquaculture at present. However, while recirculating aquaculture adopts a high-density and intensive farming model and obtains huge economic benefits, it also faces many problems. In the process of adopting high-density aquaculture in recirculating aquaculture, due to excessive bait feeding, a large amount of residual bait and excrement of farmed animals will produce a large amount of pollutants such as ammonia nitrogen, nitrite, sulfide, etc., which not only causes water pollution, but also affect the health of farmed anima...
