Problems solved by technology

The former is costly in production and requires large-scale freeze-drying and separation equipment, and the product enters the market due to storage at room temperature, the survival time of the bacteria is short, and the effect decreases after use; the latter bacteria metabolize and produce gas after a period of time, causing the plastic bottle to swell and burst. , At the same time, the death of bacteria is very high at room temperature, a large number of sediment layers, the storage time is very short, and the total number of bacteria is reduced by more than 80% in 6 months

Embodiment 1

[0077] Super-concentrated algal micro-ecological balance suspension type water quality improver is based on the mass ratio of 100 parts: green algae and other beneficial algae concentrates (cell number ≥ 10 20 CFU / ml) 85 parts, nitrogen-fixing bacteria and other beneficial bacteria concentrate (cell number ≥ 10 40 CFU / ml) 10 parts, 4.75 parts of special nutrient solution, 0.25 parts of preservation suspending agent (agar powder, dextran, seaweed polysaccharide mixture, the ratio is 12:5:1).

[0078] Its preparation method is carried out according to the following steps:

[0079] a. The cultivation of algae

[0080] Purely cultivated green algae (Scenedes, Chlorella) or diatoms are firstly cultured through primary and secondary expansion.

[0081]Primary cultivation of algae species: under the ultra-clean workbench in a sterile room, inoculate the purely cultured Scenedesmus, Chlorella, or diatom algae species that are kept on the inclined surface of the test tube into a 500m...

Embodiment 2

[0098] Super-concentrated algal micro-ecological balance suspension type water quality improver is based on the mass ratio of 100 parts: beneficial algae concentrates such as diatoms (cell number ≥ 10 20 CFU / ml) 60 copies, nitrogen-fixing bacteria and other beneficial bacteria concentrate (cell number ≥ 10 40 CFU / ml) 30 parts, 9.85 parts of special nutrient solution, 0.15 parts of preservation suspending agent (agar powder, dextran, seaweed polysaccharide mixture, the ratio is 12:5:1). Its preparation method is the same as

[0099] Example 1.

Embodiment 3

[0101] Super-concentrated algal micro-ecological balance suspension type water quality improver is based on the mass ratio of 100 parts: green algae and other beneficial algae concentrates (cell number ≥ 10 20 CFU / ml) 50 copies, nitrogen-fixing bacteria and other beneficial bacteria concentrate (cell number ≥ 10 40 CFU / ml) 35 parts, special nutrient solution 14.80 parts, preservation suspension agent (agar powder, dextran, seaweed polysaccharide mixture, the ratio is 12:5:1) 0.20 parts. Its preparation method is the same as

Abstract

A suspended water improving using super-concentrated phycobacteria for microecological balance contains proportionally the concentrated seaweed liquid, concentrated bacteria liquid, special nutritive liquid and suspending agent. It has high effect to improve water quality.

Description

technical field [0001] The invention relates to the fields of biological micro-ecological preparations and environmental protection, and is a novel super-concentrated micro-ecological balance suspension type water quality improver for aquaculture and water purification, and a preparation method thereof. Background technique [0002] In aquaculture, due to the aging of ponds, the deposition of sediment bait and a large amount of feces, harmful substances such as ammonia nitrogen, nitrite nitrogen, toxic algae toxins, hydrogen sulfide, methane, etc. Disinfectants and some biocidal chemicals prevent and control the diseases of aquaculture animals, leading to the death of some beneficial microorganisms and beneficial algae that purify the water, seriously destroying the purification ability of the water environment, losing the self-purification ability of the water body, deteriorating the aquaculture water body, and increasing the incidence of diseases. Serious and explosive tra...
