Integrated treatment equipment for aquaculture wastewater

Integrated treatment equipment for aquaculture wastewater

The wastewater from animal husbandry mainly comes from the flushing of animal husbandry and defecation of livestock and poultry. The wastewater from animal husbandry is a high concentration organic wastewater rich in a large number of pathogens, which is directly discharged into water bodies or stored in inappropriate locations. If it is washed into water bodies by rainwater, it may cause serious deterioration of surface water or groundwater quality. Due to the strong phosphorus solubility of livestock and poultry manure and urine, the phosphorus and water-soluble organic matter in manure and urine have a large amount of phosphorus solubility. If not properly treated, they can enter the groundwater layer through surface runoff and infiltration, polluting the groundwater. Based on years of experience in treating aquaculture wastewater and referring to relevant technologies at home and abroad, technicians from Quankun Environmental Protection Company have developed equipment for treating aquaculture wastewater. The equipment can be assembled or disassembled according to different or changing water quality, ultimately achieving the expected treatment effect. All indicators comply with relevant national discharge standards.

Process description:

After removing large suspended solids and impurities such as hair through a grid screen, the wastewater directly enters the initial condition tank. The initial sedimentation tank also serves as a regulating tank to homogenize water quality and quantity, while settling insoluble solids such as undigested food and feces in the wastewater. The sedimentation effluent flows into the anaerobic hydrolysis tank, where under the action of extracellular enzymes from anaerobic bacteria, large molecular organic matter is hydrolyzed and acidified into small molecules, degrading most insoluble organic matter into soluble substances Then it enters the contact oxidation tank, and after the water level reaches the set level, aeration is carried out to fully mix the wastewater with activated sludge. After the aeration is completed and the sludge settles, the supernatant is discharged. When the sludge accumulates to a certain water level, it is discharged into the sludge tank. After biological treatment, the sewage enters the secondary sedimentation tank, and after sedimentation, it is lifted to the filter for filtration before flowing into the disinfection tank for disinfection treatment and meeting the discharge standards.

Equipment advantages:

1. Strong resistance to impact loads, with an average residence time of over 6 hours using contact oxidation method.

2. It has the ability to remove nitrogen and phosphorus, and by adjusting the equipment structure, it can achieve the ability to treat industrial wastewater, domestic sewage, and urban sewage.

3. The filling materials in the contact oxidation tank are mostly soft filling composite materials, which are lightweight, high in strength, stable in physical and chemical properties, have a large specific surface area, strong in biofilm adhesion, and have high contact efficiency between sewage and biofilm.

4. An aerator is used in the contact oxidation tank for air blowing aeration to continuously float the fiber bundles, ensuring uniform aeration and mature microbial growth, which has the characteristics of activated sludge process.

5. The effluent quality is stable, with low sludge production and easy treatment.

6. Submersible pumps can be installed on the equipment to reduce project investment.

7. The equipment can be installed on the ground or buried underground. When buried underground, the upper part can be used for greening, and the factory area occupies a small area with few above ground buildings.

8. Easy to automatically control and simple management operation.

9. The device can be connected to a car to make a mobile integrated sewage treatment equipment.

Features:

1. Compact, small size, small footprint, buried structure, movable, convenient for greening and no breeding of mosquitoes and flies;

2. High removal rate of organic pollutants and stable effluent quality;

3. Easy operation, convenient construction, no need for special maintenance, and good self-protection of equipment;

4. Good water quality treatment to meet discharge standards;

5. The integrated equipment can be flexibly configured according to the quality of raw water, making it widely applicable.

6. Probiotics are highly efficient microbial strains. For special wastewater, our company can provide specialized probiotics to quickly and effectively ensure that the effluent quality meets the standard.
