Poultry farming wastewater primarily originates from the flushing of animal husbandry pens and the excrement of livestock and poultry. These effluents are highly concentrated organic waste rich in pathogens, which, when directly discharged into water bodies or unsuitable storage areas, can lead to severe degradation of surface or groundwater quality upon being washed in by rainwater. Due to the strong phosphorus solubility of animal excrement, a significant amount of phosphorus and water-soluble organic matter is present in the excrement. If not properly handled, these substances can seep through surface runoff and infiltrate the groundwater layer, contaminating it. Qiankun Environmental Protection Company's technical team, with years of experience in treating poultry farming wastewater and referencing domestic and international technologies, has developed a treatment equipment for such effluents. The equipment can be customized by adding or combining components based on varying water quality, achieving the desired treatment outcomes while meeting national emission standards.
Process Description:
Wastewater, after being screened through a grille to remove larger suspended solids and hair, etc., is directly fed into the primary sedimentation tank. This tank, which also serves as a regulating tank, equalizes water quality and volume, while allowing insoluble solids like undigested food and feces to settle. The settled water then 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 smaller molecules, and most of the insoluble organic matter is degraded into soluble substances..Then, the wastewater enters the contact oxidation tank. Once the water level reaches the set level, aeration begins to mix the wastewater with the activated sludge thoroughly. After aeration, the supernatant is discharged when the sludge settles. When the sludge reaches a certain water level, it is pumped to the sludge pond. The treated wastewater then flows to the secondary sedimentation tank, where it is clarified. After clarification, it is elevated to a filter for filtration before being transferred to a disinfection tank for disinfection and then meets the standards for discharge.
Equipment Advantages:
1High impact load resistance, average contact oxidation retention time greater than6Hour(s)
2Capable of denitrification and phosphorus removal, the equipment can be adjusted to treat industrial wastewater, domestic wastewater, and urban wastewater.
3The contact oxidation tank is filled with soft composite materials, which are lightweight, high in strength, and have stable physical and chemical properties, a large specific surface area, and strong adhesion of the biofilm, resulting in high contact efficiency between wastewater and the biofilm.
4The contact oxidation tank is aerated using an aeration device, causing the fiber bundles to continuously float and ensuring uniform aeration. This promotes the growth and maturation of microorganisms, exhibiting characteristics of the activated sludge process.
5Water output quality is stable, low sludge generation, easy to handle.
6The equipment can be fitted with a submersible pump, reducing engineering investment.
7The equipment can be installed on the ground or buried underground. When buried, the upper part can be used for landscaping, resulting in a smaller land footprint and fewer ground buildings in the factory area.
8Easy to automate control; simple management operations.
9The equipment can be mounted on a vehicle to form a mobile integrated wastewater treatment unit.
Feature Highlights:
1Compact, space-saving, buried structure, mobile, conducive to greening, and free from mosquito and fly breeding.
2High removal rate of organic pollutants, with stable effluent water quality.
3Easy to operate, easy to install, requires no special maintenance, and has good self-protection features.
4Water quality well-managed, meets discharge standards.
5The integrated equipment can be flexibly configured according to the quality of the raw water, making it widely applicable.
6Probiotics are highly effective microbial strains. For specific wastewater, our company offers specialized probiotics that can rapidly and effectively meet the water quality standards.
