Abstract

The present invention discloses biological water purification agent and its preparation method. The technological scheme of said invention is to screen out a group of microbial colony and to compound it with adsorber, activator, excipient, microelement to form the product. Said invention can decompose harmful material in water, increase dissolved oxygen in water, reduce chemical oxygen demand in water so as to achineve the aim of water purification.

Description

A kind of biological water purification agent and preparation method thereof

The present invention relates to the quality biological purification agent in fields such as a kind of aquaculture, environmental protection and preparation method thereof.

At present, culture fishery has formed industry size in China, and in national economy, occupy critical role, but because long-term intensive culture pond is aging, micro-ecological environment worsens serious day by day in the water body, self-cleaning is out of control with conciliation mechanism, uses the biological means pollution control of water, prevents that water quality deterioration from having caused people's attention.

The objective of the invention is to provide the living microorganism flora of one group of purifying contaminated water body to reach a kind of biological water purification agent of effect and preparation method thereof that purifies water.

Technical solution of the present invention is by one group of multifunctional microbial flora of screening and culturing, and is furnished with sorbent material, activator, vehicle, trace element composition.Its preparation is made (consumption is a weight part) by following component

Sorbent material 45-60 part microbiobacterial agent 25-40 part is solidified enzyme 1-10 part

Activator 1-10 part trace element 5-15 part vehicle 1-10 part

The formula optimization weight proportion scope of preparation preparation of the present invention is:

Sorbent material 45-55 part microbiobacterial agent 25-35 part is solidified enzyme 1-5 part

Activator 1-5 part trace element 5-10 part vehicle 1-5 part

The optimum weight proportioning of preparation of the present invention is;

50 parts of microbiobacterial agents of sorbent material solidify 2 parts in 3 parts of activators of enzyme for 30 parts

1 part of 10 parts of vehicle of trace element

Sorbent material described in the present invention comprises peat soil, expanded silicate, brown coal powder at least, can be single also can be blended; Microbiobacterial agent by bacterial classification, water, nutrition, yeast powder by weight than 1: 6: 25: 0.5; Microbial bacteria can be one of photosynthetic bacteria, vinelandii, genus bacillus, nitrate bacterium or their mixture; The said activator of the present invention is interior lipid biotechnological formulation; Vehicle refers to microorganism after liquid culture, adds certain nutrient, and in drying process, thalline gives nutritive substance negative and non-inactivation, and this nutritive substance mostly is milk powder or bean powder; Trace element refers to oxide compound or salts such as iron, manganese, zinc, boron, copper, cobalt, molybdenum, for beneficial microorganism provides necessary nutrition.

Preparation method of the present invention:

A, microbial bacteria is cultivated the back through I and II add vehicle, and then through making microbiobacterial agent after the cryogenic vacuum lyophilize for three grades of cultivations usefulness;

B, zymogenic bacteria made microbial inoculum after, make its curing with the dextrin coating;

C, a, b product thorough mixing are added sorbent material, activator again, thorough mixing, metering packing make product again.

This product probiotics content is greater than 300,000,000/g, proves that through thousands of mu culture experiment in a few years this product all has the effect that purifies water to seawater, freshwater aquiculture, and flora has stronger resistance, subject range pH value 6～9 intervals.

The present invention contains activator, and after product applied water body, beneficial microorganism was activated, and forms dominant population at short notice, because probiotics progressively forms sociales in water body, can effectively suppress the harmful bacterium in the water body again.In addition, because product of the present invention is to form with the multifunctional microbial bacterium, in water body, can decompose objectionable impurities in the water body in a large number.Simultaneously, the dissolved oxygen that improves in the water body has reduced chemical oxygen demand in the water body, reaches the purpose of purifying water body, and forming throw out in a large amount of reproductive processes of probiotics is the high-quality bait of filter-feeding fish, and then has improved advantage such as cultured output.

Embodiment:

Weigh raw material by following proportioning:

50 parts of microbiobacterial agents of sorbent material solidify 2 parts in 3 parts of activators of enzyme for 30 parts

1 part of 10 parts of vehicle of trace element

Production method is as follows:

To add vehicle after photosynthetic bacteria, vinelandii, genus bacillus, the nitrate bacterium process I and II biological culture, and then through after freezing, the drying of cryogenic vacuum, make photosynthetic bacteria powder 1kg, vinelandii powder 0.6kg, genus bacillus 1.2kg, nitrate bacterium 0.3kg respectively, make three grades of mixed solution 180kg after the photosynthetic bacteria inoculation.Make zymogenic bacteria 3kg again, add dextrin and solidify, the above-mentioned bacterium liquid that makes is added sorbent material 550kg, add micro-10kg, activator 21g thorough mixing and mix thoroughly, measure, pack and make finished product.In use, water quality cleansing agent (pulvis) is poured in the container, be blended into 10-15 clear water dilution doubly, every mu of consumption 10-15kg evenly splashes in the pond then.Duration of service can be in the fish pond, preemergence application is put in the shrimp pond, sends out a pond, the pool and uses and can extend to the wheel animalcule peak period.
