Problems solved by technology

[0004] The Chinese invention patent of CN 103060238 B discloses a micro-ecological water purifier for aquatic products and its preparation and application method. In the inventive method, Bacillus cereus, Bacillus spp. The micro-ecological water purifying agent is obtained by mixing equal volumes of the micro-ecological water purifying agent, which has the characteristics of simple preparation, but the inventive method only uses the fermented liquid as the water purifying agent, and the sedimentation effect on the refractory substances in the water body is not ideal, and cannot reduce The content of heavy metal ions in the water body, the water purification effect is not obvious, and the method of the present invention needs three kinds of comparatively loaded down with trivial details fermentation steps, is unfavorable for industrial application, so its popularization value is not big

Embodiment 1

[0020] Aquaculture water quality treatment agent, its preparation method comprises the following steps:

[0021]1) Extract the dried Moringa oleifera seed powder with 3 times the amount of 90% ethanol to extract the Moringa oleifera seed components, stir thoroughly for 30 minutes, take the precipitate and dry it at room temperature, and then dry it with 5 times the weight of 0.5mol / L sodium chloride solution The Moringa seed precipitate was stirred for 30 minutes, filtered through a 6-micron filter paper, and then filtered with a 0.5-micron glass fiber filter paper. The filtered liquid was the crude extract of Moringa seed; 2) Soak the glucose gel in distilled water for 45 hours to use It fully swells and removes floating gel particles. A mixture of standard products of known molecular weight lactic acid bacterium peptide and insulin is used to obtain the relationship between elution time and molecular weight. Components of -6kDa, low-temperature drying remember Moringa oleife...

Embodiment 2

[0023] Aquaculture water quality treatment agent, its preparation method comprises the following steps:

[0024] 1) Extraction: Shell healthy and clean Moringa oleifera seeds, crush them and pass through an 80-mesh sieve, then dry them. Use 4 times the amount of 95% ethanol to extract the components of Moringa oleifera seeds, stir them thoroughly for 60 minutes, and take The precipitate was dried at room temperature, then stirred with 10 times the weight of 0.1mol / L sodium chloride solution and the dry Moringa seed precipitate for 45 minutes, filtered through 11 micron filter paper, and then filtered with 1.0 micron glass fiber filter paper. The liquid is the crude extract of Moringa seeds;

[0025] 2) Purification of flocculation active substances: Soak glucose gel in distilled water for 48 hours to fully swell and remove floating gel particles, and use a mixture of standard products of known molecular weight lactobacillus peptide and insulin to obtain the relationship betwee...

Embodiment 3

[0029] Aquaculture water quality treatment agent, its composition and parts by weight are: 2 parts of Moringa seed flocculant, 3 parts of microbial flocculant, 1 part of Pseudomonas fluorescens, 0.5 part of Vibrio alginolyticus, bacteriophage Bdellovibrio 0.5 parts, 2 parts of cellulase, 4 parts of polyaluminum salt, 5 parts of polyacrylamide, 4 parts of potassium hydrogen persulfate complex, 0.4 parts of sodium thiosulfate, 50 parts of diatomaceous earth, 70 parts of distilled water, the treatment agent can effectively Degradation of nitrogen, phosphorus, organic matter, cellulose, heavy metal ions and other pollutants in the water body can also effectively inhibit the growth of algae, reduce the turbidity of the water body, reduce the eutrophication of the water body, and have a strong flocculation and precipitation of suspended solids in the water body It is an efficient and safe aquaculture water quality treatment agent.

[0030] As preferably, aquaculture water quality tr...

Abstract

The invention discloses a water quality treatment agent for aquaculture. The water quality treatment agent comprises the following components in parts by weight: 3-5 parts of a moringa oleifera seed flocculating agent, 2-4 parts of a microbial flocculant, 1-2 parts of a composite microbial preparation, 1.5-2 parts of an enzyme preparation, 4-6 parts of polyaluminum chloride salt, 5-8 parts of polyacrylamide, 4-5 parts of a potassium hydrogen persulfate complex, 0.2-0.4 part of a bacteria protective agent, 40-50 parts of a filler and 60-80 parts of distilled water. The water quality treatment agent has the beneficial effects that the treatment agent can achieve the effects of effectively degrading nitrogen, phosphorus, organic matters, cellulose, heavy metal ions and other pollutants in a water body, effectively inhibiting algae growth, reducing the water turbidity and reducing eutrophication of the water body and has an excellent flocculent settling effect on suspended solids in the water body, and is a high-efficiency and safe water quality treatment agent for aquaculture.

Description

technical field [0001] The invention relates to the field of water quality treatment agents, in particular to an aquaculture water quality treatment agent. technical background [0002] In recent years, intensive aquaculture has developed rapidly at home and abroad, especially in my country, and its aquaculture production has accounted for about 2 / 3 of the world's aquaculture production. my country's current aquaculture industry is in a historical transition period from the traditional high-yield stocking model to large-scale farming, quality and benefit. , and in the process of aquaculture, the feed residues and pollutants formed by the excrement of fish, shrimp, and crabs have polluted the water body and pond sediment, making the aquaculture water body increasingly eutrophic, and affecting the surrounding water environment and ecological environment. caused increasing harm. According to the data of the aquaculture industry in Jiangsu Province, the annual water exchange vol...
