Cattle wastewater from organic pastures is a high-concentration organic wastewater with high concentration, high ammonia nitrogen, suspended solids and high pathogenic bacteria. Cattle farm wastewater mainly comes from site cleaning, domestic sewage, animal excrement, etc. The COD, ammonia nitrogen, total phosphorus and SS (suspended solids) indicators of this aquaculture wastewater are high in concentration, and it contains a certain amount of pathogens. If it is discharged directly, it will cause great pollution to the surrounding water bodies and environment, and endanger human health. Therefore, effective process treatment must be carried out, such as treatment to meet the agricultural irrigation water discharge standards, fish farming in fish ponds or fermentation into liquid organic fertilizer for returning to the field to realize wastewater resource utilization.
Characteristics of cattle wastewater quality: high COD, ammonia nitrogen, total phosphorus, SS content, high chroma; high pathogenic microorganisms, strong odor; good biodegradability.
The customer's cattle wastewater area is composed of all manure and milking hall sewage. After being treated by the "solid-liquid separation-anaerobic-aerobic-MBR membrane" system, the COD in the sewage is about 300, and the wastewater contains a large amount of E. coli, roundworm eggs, etc., which is difficult to meet the national agricultural irrigation water GB5084-2021 standard. Therefore, efficient sterilization and COD removal treatment measures are essential.
Shanruo Environment continues to learn from experience and has formed a set of high-value deep water treatment solutions for professional treatment of aquaculture wastewater, providing customers with a series of water treatment services including "project consulting, water quality analysis, scheme design, project construction, equipment production, water operation" and so on. At the same time, through the pain points, water quality conditions and key needs of the in-depth aquaculture industry, a complete solution for the industry's wastewater is reshaped. A certain animal husbandry group's wastewater deep treatment project is one of the typical cases.
Key innovations of LCO ozone catalytic oxidation filler:
Using composite high-strength silicon aluminum as a catalytic carrier, the catalytic components that are not easy to lose are loaded, which improves the stability of the catalyst. The carrier is prepared with special adhesive materials, which has high mechanical strength and long service life. The selection of catalytic carrier is particularly critical for the continuous and stable loading of effective catalytic components. At the same time, the strength of the catalytic carrier is also extremely important. Only by selecting the same phase and high-strength carrier can the efficient and stable loading of the catalytic components be guaranteed, and very low wear can be maintained during operation;
Carefully select the active components of the catalytic filler, and use transition metals, rare metals, and rare earth metals as effective catalytic components to ensure the continuous high efficiency and spectrum of the ozone oxidation effect, avoid the singleness of the catalyst in complex water, reduce the influence of organic components in water on the catalyst, increase the conversion rate of ·OH and improve the ozone oxidation efficiency;
According to the catalytic carrier and catalytic components Features, using high temperature sintering technology to ensure high utilization and high adhesion of active components, while reducing the loss rate of catalytic fillers and preventing secondary pollution;
Catalytic filler strength ≥100N/particle, specific surface area ≥200, catalytic filler without loss, no need for regular addition;
If the water inlet conditions are met, we will provide free technical services if there are problems within the warranty period. If the filler efficiency decreases due to wear and tear caused by long-term water flushing after a certain number of years of operation, our company can provide filler replacement services, avoiding the purchase cost and waste disposal cost of filler replacement, and greatly reducing the wastewater operation cost;
Synergistic use of homogeneous catalysis and heterogeneous catalysis to increase the ·OH generated in water concentration, thereby improving the ozone oxidation effect, and the oxidation efficiency is 2 to 4 times higher than that of simple ozone oxidation;
The ozone dissolved gas form adopts a partial reflux high-efficiency jet form, which greatly increases the solubility rate of ozone in water and accelerates the reaction rate. The unused ozone and the generated ·OH after the catalyst can be mixed with fresh water again, fully improving the ozone utilization rate and catalytic efficiency, reducing the amount of ozone input and reducing operating costs;
It can reduce the reaction activation energy or change the reaction process, so as to achieve the purpose of deep oxidation and maximize the removal of organic pollutants.
Stable operation, becoming the leading process for deep treatment of aquaculture wastewater
Since the project was put into operation, the operating cost is reasonable, the effluent is stable and meets the standards, and the production environment is friendly, which has achieved the harmlessness, stabilization and resource utilization of sewage. The application of Shanruo Environmental Deep Treatment Process solves the problem of unqualified traditional biochemical effluent indicators, and is simple to operate, stable in operation, and does not require complex operations such as dosing, which greatly saves the labor and agent costs of sewage operation and has won praise from customers.
