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 water 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 in large quantities. If not properly handled, they can contaminate the groundwater through surface runoff and infiltration. Based on years of experience in treating wastewater from livestock farming and referring to relevant domestic and international technologies, the technical team at Pu膜Environmental Protection Co., Ltd. has developed a treatment equipment for livestock farming wastewater. This equipment can adjust the components by adding or assembling to meet the expected treatment effects according to different or changing water quality, and all indicators comply with national emission standards.
Process Description:
Wastewater is first filtered through a grille screen to remove large suspended solids and hair, etc., and then it flows directly into the primary sedimentation tank. The primary sedimentation tank also serves as a regulating tank to equalize water quality and volume, while settling down insoluble solids like undigested food and feces. The settled water then enters the anaerobic hydrolysis tank, where, under the action of extracellular enzymes of 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, 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 accumulates to a certain level, it's pumped into the sludge pond. The treated wastewater flows into the secondary sedimentation tank, is lifted to the filter for filtration, and then proceeds to the disinfection pond for treatment before meeting the standards for discharge.
Equipment Advantages:
1High impact load resistance, average residence time in contact oxidation process is greater than6Hour(s)
2Capable of denitrification and phosphorus removal; by adjusting the equipment structure, it can achieve the capability to treat industrial wastewater, domestic wastewater, and urban wastewater.
3The contact oxidation pond 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 pond employs aeration blowers for aeration, causing the fiber bundles to continuously float and move, ensuring uniform aeration, microbial growth and maturation, and exhibiting characteristics of the activated sludge process.
5Water output quality is stable, sludge generation is low, and treatment is easy.
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 top can be used for landscaping, resulting in a smaller land area for the factory and fewer above-ground structures.
8Easy to automate, with simple operational management.
9The equipment can be mounted on a vehicle to form a mobile integrated wastewater treatment unit.
Feature Highlights:
1Compact, space-saving, buried structure, portable, conducive to greening, and free from mosquito and fly breeding.
2High removal rate of organic pollutants, with stable effluent water quality.
3Simple operation, easy construction, no special maintenance required, and good self-protection for the equipment.
4The water quality is well-managed, meeting the required emission 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 can provide specialized probiotics to quickly and effectively meet the water quality standards of the effluent.
Application Range:
Integrated wastewater treatment equipment is suitable for residential communities, villages, townships, office buildings, shopping malls, hotels, restaurants, government agencies, schools, highways, railways, factories, mines, tourist attractions, and the treatment and reuse of domestic wastewater as well as similar small and medium-scale industrial organic wastewater from slaughtering, aquatic product processing, and food industries.
