Problems solved by technology

Early carriers such as sodium alginate and polyvinyl alcohol have poor gel stability
There are also ceramsite as the carrier, which is combined with the microorganisms by the film-hanging effect and physical adsorption on the surface. The force is weak, it cannot be effectively combined, and the impact resistance is very poor.
Invention patent "Functionalized ceramsite carrier and its immobilized microorganism treatment sewage technology" (China Patent No.: 02129972.2) discloses a functional macroporous ceramsite carrier for water purification, with rings on the pore surface Oxygen or primary amino reactive functional groups, by adding a cross-linking agent to fix the microorganisms on the ceramsite, due to t

Example Embodiment

[0023] Example 1

[0024] First, select the materials: use Bacillus for microbial bacteria, use 20-mesh crucible granules for porous natural ore particles, and use a mixture of bran, soybean meal, corn flour, and rice bran as a solid medium (requires bran, soybean meal, corn flour, rice bran without Impurities, no mold, and the weight ratio of each component is as follows: bran: soybean meal: corn meal = 6.5-8:1-2.5:1-1.5), the weight ratio between the porous natural ore and the solid medium is 1 : About 2, a small amount of trace elements are added to the solid medium, and it is used after sterilization.

[0025] The preparation steps are as follows:

[0026] (1) Add stilbene particles and an appropriate amount of quicklime water to the solid culture medium and mix them thoroughly, then autoclave the solid mixture, and an appropriate amount of quicklime water can adjust the pH of the mixture to 6.5-7.2; autoclave sterilization The conditions are as follows: sterilization temperat...

Abstract

The invention relates to a water treatment technique with immobilized microorganisms, and discloses a microorganism slow release body with good slow release effect and capable of controlling water pollution of cage culture in running water areas or rivers/lakes and a preparation method thereof. The microorganism slow release body uses porous natural ore granules as a carrier, and is embedded into the spaces in the porous natural ore granules. The microorganism slow release body is placed into water when application, the microorganisms in the pores revive and grow to predominant bacteria around the porous natural ore granules to gradually absorb ammonia nitrogen organics and nitrite in water, so as to clean water. The microorganism slow release body is especially suitable for controlling water pollution. In addition, the porous natural ore granules have better slow release function and can flow with water to slowly release live bacteria in pores, and the released live bacteria are diluted or dispersed in water, so as not to cause adverse influence on the original ecological environment in the water body.

Description

technical field [0001] The present invention mainly relates to microbial water purification treatment technology, which is applied to water pollution environment treatment and aquaculture industry, specifically relates to immobilized microbial water purification treatment technology, and particularly relates to a kind of slow-release effect, which can control flowing waters or rivers and lakes. The invention discloses a slow-release microbial water purification body polluted by box-cultured water and a preparation method thereof. Background technique [0002] At present, microbial remediation is the most widely used and researched environmental treatment method, because this type of method has the advantages of low cost, good treatment effect, and no secondary pollution. [0003] Among them, in the fields of water pollution environmental control and aquaculture, beneficial live bacteria microbial water purifiers are often used in the prior art. This type of microbial water ...
