Embodiment 1

[0019] Example 1: Preparation and installation of composite microbial membrane for in-situ purification of aquaculture water

[0020] (1) The polypropylene bulky silk with large specific surface area is selected as the raw material, and the soft packing made of mechanical weaving is used as the immobilized carrier for water purification microorganisms.

[0021] (2) Prepare 2 parts of cultured Paenibacillus polymyxa bacteria solution, 3 parts of Lactobacillus plantarum bacteria solution, 3 parts of Rhodobacter sphaeroides bacteria solution, 2 parts of Rhodococcus pyridineophilus bacteria solution, 2 parts of Bacillus amyloliquefaciens bacteria solution Parts (the bacterial concentration of the selected bacterial solution is greater than 5×10 8 CPU / ml), after the bacteria solution is prepared, add 15 grams of food-grade konjac gum to each liter of the bacteria solution, and stir evenly to make a compound bacteria solution.

[0022] (3) Put the compound bacteria solution into t...

Embodiment 2

[0026] Example 2: In-Situ Purification of Aquaculture Water Body Composite Microbial Membrane Applied to Purify Aquaculture Water Body

[0027] The experimental base is located in the coastal area of ​​Guangdong. Four high-level culture ponds of Penaeus vannamei (each pond covers an area of ​​3 mu and the depth of the pond is 2.5 meters) are divided into two control ponds without composite microbial film and two with composite microbial film. ponds, each pond puts 500,000 shrimp seedlings, and the breeding method is the same. The ammonia nitrogen content in the breeding water in the treatment pond can be stably controlled below 0.5 mg / L, and the nitrite nitrogen can be controlled below 0.8 mg / L; while the ammonia nitrogen content in the breeding water in the control pond fluctuates between 0.5 and 1.5 mg / L, and The higher the temperature, the greater the concentration of ammonia nitrogen, and the content of nitrite nitrogen fluctuates between 1.0 and 2.5 mg / L most of the time,...

Abstract

The invention provides an aquaculture water in-situ purification composite microbial membrane and a using method thereof, and belongs to the technical field of aquaculture and environmental protection. A functional element of the composite microbial membrane is a membrane component in which paenibacillus polymyxa, lactobacillus plantarum, rhodobacter sphaeroides, rhodococcus pyridinovorans, bacillus amyloliquefaciens and other beneficial microorganisms are immobilized. A preparation process of the aquaculture water in-situ purification composite microbial membrane comprises selecting of a soft packing microorganism carrier, composite bacteria liquid preparation, microorganism immobilization and other steps; the composite microbial membrane is mounted in aquaculture water, beneficial microbes begin activation reproduction, long-term regulation of microbial ecology of the aquaculture water can be realized, ammonia nitrogen, nitrite and hydrogen sulfide and other toxic and harmful substances in pond can be controlled, metabolites can be licked by farmed fish, shrimp, and other aquatic organisms, so that the immunity is improved, the growth speed of the farmed species is increased, and the aquaculture water in-situ purification composite microbial membrane is especially adapt to ponds for high density aquaculture of shrimp, crab, fish and the like.

Description

technical field [0001] The invention relates to a composite microbial membrane device for in-situ purification of aquaculture water. The functional element of the device is a membrane component immobilized with various beneficial microorganisms and a method for purifying aquaculture water. Background technique [0002] In recent years, my country's intensive aquaculture has developed rapidly, and the annual output of aquatic products has exceeded 56 million tons, of which more than 70% are artificial breeding. Excessive fertilization and baiting are often carried out in high-density aquaculture. Residual bait, fish fertilizers, fish medicines, farmed animal excrement and biological debris can easily cause ammonia nitrogen, nitrite nitrogen, hydrogen sulfide, and chemical oxygen demand in the aquaculture water. (COD), biochemical oxygen demand (BOD) and other pollutants exceed the standard, which is very unfavorable to the growth of farmed animals and reduces the yield and qu...
