Poultry and livestock farming wastewater primarily originates from the flushing of animal pens and the excrement of livestock. This type of wastewater is a high-concentration organic waste rich in pathogens, and its direct discharge into water bodies or improper storage sites is unsuitable. Rainwater runoff can lead to severe degradation of surface or groundwater quality. Due to the strong phosphorus solubility in animal excrement, the phosphorus and water-soluble organic matter in the excrement are in significant quantities. Improper handling can lead to contamination of groundwater through surface runoff and filtration. Based on years of experience in treating farming wastewater and referencing domestic and international technologies, our company's technical team has developed a treatment equipment for farming wastewater. The equipment can be customized by adding or combining components according to varying water quality, achieving the desired treatment effects and meeting national emission standards.
Process Description:
Wastewater is first treated by a grille screen to remove larger suspended solids and impurities such as hair. It then directly enters the primary sedimentation tank, which also serves as a regulating tank to homogenize water quality and volume. Simultaneously, insoluble solids like undigested food and feces settle to the bottom. The settled water 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..Then, the wastewater enters the contact oxidation tank, where it's aerated once the water level reaches the set level, ensuring thorough mixing with the activated sludge. After aeration ends and the sludge settles, the supernatant is discharged. When the sludge reaches a certain water level, it's pumped into the sludge pond. The treated wastewater flows into the secondary sedimentation tank, is lifted to the filter after sedimentation, and then flows into the disinfection tank for treatment before meeting standards and being discharged.
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 handle industrial wastewater, domestic wastewater, and urban wastewater.
3The contact oxidation pool is filled with soft composite materials, which are lightweight, high in strength, stable in physical and chemical properties, have a large specific surface area, and strong adhesion of the biofilm, resulting in a high contact efficiency between wastewater and the biofilm.
4The contact oxidation tank is aerated using an aerator to continuously agitate the fiber bundle, ensuring uniform aeration, microbial growth and maturation, and exhibiting characteristics of the activated sludge process.
5Efficient water output with stable quality, low sludge generation, and easy processing.
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.
8Easy to automate and manage with simple operational procedures.
9The equipment can be connected to a vehicle to form a mobile integrated wastewater treatment unit.
Feature Highlights:
1Compact, space-saving, with a small footprint, buried structure, mobile, ideal for landscaping, and free from mosquito breeding.
2High removal rate of organic pollutants, stable effluent water quality.
3Simple operation, easy installation, no special maintenance required, and good self-protection for the equipment.
4The water quality is well-managed, meeting the emission standards.
5Integrated equipment can be flexibly configured according to the quality of raw water, making it widely applicable.
6Probiotics are high-efficiency microbial strains, and for specific wastewater, our company can provide specialized probiotics that quickly and effectively meet the water quality standards.
Application Scope:
Integrated wastewater treatment equipment is suitable for residential communities, villages, towns, office buildings, shopping malls, hotels, restaurants, government agencies, schools, highways, railways, factories, mines, tourist attractions, and other similar facilities for the treatment and reuse of domestic wastewater and small to medium-sized industrial organic wastewater from slaughtering, aquatic product processing, food, and similar sectors.
