Poultry and livestock farming wastewater primarily originates from the flushing of animal pens and animal excrement. Poultry and livestock waste water is a highly concentrated organic wastewater rich in pathogens. Direct discharge into water bodies or inappropriate storage locations is unsuitable, as it can lead to severe degradation of surface or groundwater quality when washed into the water by rain. Due to the strong phosphorus solubility of animal feces and urine, a large amount of phosphorus and water-soluble organic matter are present in the feces, which, if not properly handled, can contaminate groundwater through surface runoff and infiltration. Based on years of experience in treating wastewater from poultry and livestock farming, and referring to domestic and international technologies, our technical team at Pulpam Environmental Company has developed and produced treatment equipment for poultry and livestock waste water. This equipment can adjust the components according to varying water quality, achieving the desired treatment effect while meeting national emission standards.
Process Description:
Wastewater, after being screened through a grid to remove larger suspended solids and impurities like hair, is directly fed into the primary sedimentation tank. This tank serves both as a sedimentation tank and a regulating tank to homogenize water quality and volume, while allowing insoluble solids such as undigested food and feces to settle. The settled water then flows into an anaerobic hydrolysis tank, where, under the action of extracellular enzymes of 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..After entering the contact oxidation tank, the water level is adjusted to the set level and then aeration begins to thoroughly mix the wastewater with the activated sludge. Once aeration ends and the sludge settles, the supernatant is discharged. When the sludge accumulates to a certain level, it is drained into the sludge tank. The treated wastewater then flows into the secondary sedimentation tank, where it is sedimented before being pumped to the filter for filtration. After passing through the disinfection tank, it is treated and meets the discharge standards.
Equipment Advantages:
1High impact load resistance, average residence time in contact oxidation method exceeds6Hour.
2Capable of denitrification and phosphorus removal, the equipment can be adjusted to handle 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. They also feature a large specific surface area and strong adhesion of the biofilm, resulting in a high efficiency of contact between wastewater and the biofilm.
4The contact oxidation pond utilizes aeration blowers for aeration, causing the fiber bundles to continuously float and ensuring even aeration. This promotes the growth and maturation of microorganisms, exhibiting characteristics of the activated sludge process.
5Efficient water output with stable quality, low sludge generation, and easy treatment.
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 small land area required for the factory and fewer above-ground buildings.
8Easily automated for convenient operation and management.
9The equipment can be mounted on a vehicle to create a mobile integrated wastewater treatment unit.
Feature Highlights:
1Tight, compact, with a small footprint, underground structure, portable, conducive to greening, and free of mosquito and fly breeding.
2High removal rate of organic pollutants, with stable effluent water quality.
3Easy to operate, simple to install, requires no special maintenance, and has good self-protection features.
4Water quality is well-managed, meeting discharge standard requirements.
5Integrated equipment can be flexibly configured according to the quality of raw water, making it widely applicable.
6Probiotics are highly effective microbial strains. For specific wastewater, our company can provide specialized probiotics that rapidly and effectively meet water quality standards.
Application Scope:
Integrated wastewater treatment equipment is suitable for residential communities, villages, towns, office buildings, shopping malls, hotels, restaurants, schools, highways, railways, factories, mines, tourist attractions, etc., for the treatment and reuse of domestic wastewater and similar small and medium-scale industrial organic wastewater from slaughtering, aquatic product processing, and food industries.
