Problems solved by technology

[0002] The discharge of domestic sewage and industrial wastewater deteriorates the quality of the water body, endangers the survival of aquatic organisms, and causes the water body to lose its original ecological function and use value.
In addition to the direct damage and impact on the ecological system caused by the discharge of sewage, the accumulation, migration and transformation of pollutants will also cause a variety of derivative environmental effects, causing indirect harm to the ecological system and human society. Sometimes this indirect environmental effect The harm is greater than the direct harm caused at that time, and it is more difficult to eliminate
[0003] Aquaculture wastewater discharges a large amount of H 2 S, N, P, etc. not only pollute the environment, but are also a waste of resources. The current treatment methods either fail to meet the emission standards, or are large-scale engineering investment, high operating costs, and large-scale land occupation. Large-scale farms discharge daily The amount of wastewater is large and concentrated, and the wastewater contains a large amount of pollutants, such as heavy metals, residual drugs, and a large number of pathogens. Therefore, if it is discharged into the environment or directly used for agriculture without treatment, it will cause damage to the local ecological environment and farmland. serious pollution of

Embodiment 1

[0019] The seaweed residue is sterilized and sterilized at high temperature (above 100°C), soaked for 48 hours, crushed to 80 mesh, ground to 120 mesh, extracted from it, mannitol and sodium alginate, put into a pulper for pulping, and placed in cold storage Rhodopseudomonas photosynthetic bacteria strains, co-cultivated in a culture tank with a temperature not exceeding 35°C for 3 days; wood fiber 30-35, mineral powder 10-12, sand powder 20-25, wheat husk 1-2, soybean meal 1 ~2. Zeolite powder 10~15 is sent to the sterilizer according to the total mass percentage, and sterilized at high temperature for 24 hours; molasses 2, water 10, salt 0.01, amino acid 5, cultured bacteria liquid 10 and the above-mentioned mixture through the sterilizer according to The total mass percentage is mixed, and it enters the mixing tank through the feeder for stirring. After being fully stirred evenly, it reacts at room temperature and pressure; finally, it is made into oval purification balls wi...

Embodiment 2

[0021] Repeat the same steps as described in Example 1, but the following mass ratios are changed to: wood fiber 30~35, mineral powder 10~12, sand powder 20~22, wheat bran 1~2, soybean meal 1~2, zeolite Powder 10-12, molasses 2, water 10, salt 0.03, amino acid 5, cultured bacteria liquid 10.

Embodiment 3

[0023] Repeat the same steps as described in Example 1, but the following mass ratios are changed: wood fiber 25~30, mineral powder 10~15, sand powder 15~20, wheat bran 2~3, soybean meal 1~2, zeolite Powder 10-15, molasses 2, water 10, salt 0.03, amino acid 5, cultured bacteria liquid 10.

Abstract

The invention discloses a novel biological water purifying sphere and a preparation process thereof. The purifying sphere is prepared by taking a seaweed bio-fungus as a reaction matrix and cooperating with different auxiliary agents and various auxiliary materials to undergo particular extruding process. The preparation process is simple. The prepared purifying sphere has the advantages of effectively decomposing the impurities in the sewage, quickly degrading the harmful amino nitrogen in water, removing such harmful substances as ammonia, hydrogen sulfide and the like, removing peculiar odors, increasing dissolved oxygen, removing underwater pollution and improving the water quality, etc.

Description

technical field [0001] The invention relates to a purification ball in the fields of aquaculture, environmental protection and the like, in particular to a novel biological water quality purification ball and a preparation process thereof. Background technique [0002] The discharge of domestic sewage and industrial wastewater deteriorates the quality of water bodies, endangers the survival of aquatic organisms, and causes water bodies to lose their original ecological functions and use values. In addition to the direct damage and impact on the ecological system caused by the discharge of sewage, the accumulation, migration and transformation of pollutants will also cause a variety of derivative environmental effects, causing indirect harm to the ecological system and human society. Sometimes this indirect environmental effect The harm caused by it is greater than the direct harm caused at that time, and it is also more difficult to eliminate. [0003] Aquaculture wastewate...
