Integrated aquaculture wastewater treatment equipment

Introduction to the process of integrated wastewater treatment equipment for aquaculture:
The wastewater collected by the breeding farm first passes through a grid pool, where coarse solid debris is removed through an artificial grid before entering a regulating pool. The regulating pool can adjust the water quality and quantity, and has a uniform regulating effect on severe fluctuations in water quality and quantity, so that its concentration meets the fermentation requirements.

The sewage is lifted into the anaerobic fermentation tank. Wastewater is in an anaerobic state, and through the action of anaerobic and methanogenic bacteria, organic matter in the wastewater is decomposed into methane water and carbon dioxide. Anaerobic effluent enters the biological aerobic contact oxidation tank for aerobic biochemical treatment. The small molecule organic matter hydrolyzed in the anaerobic tank is further decomposed by aerobic microorganisms here; There are biological fillers installed in the pool, and the bottom of the pool is aerated. Aerobic bacteria attach to the fillers to form biofilms, which rely on organic matter in the sewage to provide nutrients. Under sufficient aeration conditions, the organic matter in the sewage is consumed, achieving the goal of reducing organic matter in the sewage.

After contact oxidation, the effluent is treated by sedimentation and flows into the oxidation pond. Aeration equipment is installed in the oxidation pond to further treat the sewage. The oxidation pond has high treatment efficiency for organic sewage with low concentration, and also has the effect of removing nitrogen and phosphorus. After treatment in the oxidation pond, the sewage fully meets the standards for agricultural water. After passing through the oxidation pond, the sewage is injected into the reuse water tank, which is equipped with a reuse water pump. 60% of the treated sewage is used as flushing water for the breeding farm through the reuse water pump. The remaining 40% of the standard water is raised here as irrigation water for farmland, achieving the goal of full recycling.

The sludge generated during the sewage treatment process first enters the sludge concentration tank for dewatering, and then is pumped into the sludge drying bed for drying treatment. The dried sludge is sent to the composting workshop and mixed with feces for composting, and then made into organic fertilizer for export.

Advantages of integrated aquaculture wastewater treatment equipment:
1. Integrated development and production of Weifang Shanshui Environmental Protection Water Treatment Equipment Co., LtdSewage treatment equipmentMade of carbon steel anti-corrosion treatment or stainless steel components, assembled on-site, lightweight, easy to transport, and convenient to install;
2. The anti-corrosion structure of glass fiber reinforced plastic, carbon steel and stainless steel is adopted, which has excellent characteristics such as corrosion resistance and aging resistance, with a service life of more than 60 years;
3. Placed above or below the surface, it saves land and does not require building, heating, or insulation. Maximized device integration and reduced footprint;
4. No pollution, no odor, reducing secondary pollution;
5. The integrated aquaculture wastewater treatment equipment is not limited by the amount of wastewater, and is flexible and adaptable. It can be used individually or in combination with multiple devices.
6. The entire equipment processing device is equipped with PLC automatic electrical control equipment and equipment fault alarm equipment, which operates safely and reliably. Generally, there is no need for dedicated personnel to manage it, and only timely maintenance and upkeep of the aquaculture wastewater treatment equipment is required, with low management costs.
