Livestock farming wastewater primarily originates from the flushing of animal pens and the excrement of livestock and poultry. This type of wastewater is a high-concentration organic waste rich in pathogens, which, if directly discharged into water bodies or stored in inappropriate locations, can lead to severe deterioration of surface or groundwater quality upon being washed into water bodies by rain. Due to the strong phosphorus solubility of animal excrement, the phosphorus and water-soluble organic matter in the excrement are highly soluble. If not properly handled, they can enter the groundwater layer through surface runoff and infiltration, polluting the groundwater. Based on years of experience in treating wastewater from livestock farming and referencing domestic and international technologies, the technical team at Pu膜Environmental Protection Company has developed a treatment equipment for livestock farming wastewater. This equipment can adjust the components according to the varying water quality, achieving the desired treatment effect and meeting the national emission standards.
Process Description:
Wastewater is initially treated by a grille screen to remove larger suspended solids and impurities such as hair. It then flows directly into the primary sedimentation tank, which also serves as a regulating tank to equalize water quality and volume. During this process, insoluble solids like undigested food and feces settle to the bottom. The settled water is then transferred to an anaerobic hydrolysis tank, where, under the action of extracellular enzymes from anaerobic bacteria, large organic molecules are 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 pond. Once the water level reaches the set level, aeration begins to thoroughly mix the wastewater with the activated sludge. After aeration ends and the sludge settles, the supernatant is discharged. When the sludge accumulates to a certain water level, it is pumped to the sludge pond. The treated wastewater then flows into the secondary sedimentation tank, where it is clarified before being lifted to the filter for filtration. After passing through the disinfection pond for treatment, it meets the standards for discharge.
Equipment Advantages:
1High impact load resistance, average residence time in contact oxidation method exceeds6Hour(s)
2Nitrogen and phosphorus removal capability; can handle industrial, domestic, and urban wastewater through adjusting equipment structure.
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 high contact efficiency between wastewater and the biofilm.
4The contact oxidation tank utilizes aeration blowers for aeration, causing the fiber bundle to continuously float, ensuring uniform aeration, promoting the growth and maturation of microorganisms, and exhibiting characteristics of the activated sludge process.
5Efficient water discharge 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 smaller land area for the factory and fewer ground buildings.
8Easy to automate and with simple operational management.
9The equipment can be mounted on a vehicle to form a mobile integrated wastewater treatment unit.
Features:
1Compact, space-saving, buried structure, movable, conducive to greening, and free from mosquito breeding.
2High removal rate of organic pollutants, with stable effluent water quality.
3Easy to operate, convenient to install, no special maintenance required, and good self-protection for the equipment.
4Water quality well-managed, meets discharge standard requirements.
5Integrated equipment can be flexibly configured according to the quality of the raw water, making the equipment widely applicable.
6Probiotics are high-efficiency microbial strains. For specific wastewater, our company offers specialized probiotics that can rapidly and effectively meet the water quality standards.
