▋Product Overview
The self-supporting nitrogen removal material is a nitrogen removal biological carrier developed by HaiZhiYan and a well-known scientific research team over eight years. It is used to solve the problems of low total nitrogen removal efficiency, difficulty in removal, and high removal cost in municipal domestic sewage treatment, industrial wastewater treatment, and natural water body restoration processes both domestically and internationally.
This material is supported by the HaiZhiYan environmentally friendly new self-sustaining denitrification (SCAD) technology system, achieving denitrification and phosphorus removal through synergistic autotrophic/heterotrophic denitrification. It eliminates the dependence on organic carbon sources in the traditional wastewater treatment denitrification process, enabling efficient and low-cost removal of total nitrogen from wastewater. It features high mechanical strength, strong porousness, high mass transfer capacity, and is naturally pollution-free.
▋Product Advantages
1. The filler has a large specific surface area, rich pore structure, strong microbial loading capacity, and is prone to biofilm formation, ensuring a high biomass in the filter tank per unit volume.
2. Avoid the breakthrough phenomenon caused by excessive addition of traditional carbon sources, and completely eradicate the issue of elevated effluent COD
3. Strong shock load resistance: It exhibits strong adaptability to changes in the quality and quantity of domestic sewage, and maintains good operational stability.
4. Possess a certain capability for simultaneous nitrogen and phosphorus removal;
5. Nitrogen removal effect: The total nitrogen removal rate is 50% to 95%, and the effluent can meet the surface water standard;
6. Low processing cost: It saves substantial expenses on carbon source addition and the investment in related dosing equipment, reducing operating costs by 30% - 70%.
7. Simple operation and maintenance, high degree of automation, and low requirements for operation and management personnel.
▋Product Application
1. Municipal wastewater treatment: It is suitable for the advanced treatment of total nitrogen in municipal wastewater treatment plants, ensuring that the total nitrogen in the effluent meets standards and reducing the operational costs of nitrogen removal.
2. Small-scale integrated wastewater treatment is suitable for decentralized wastewater treatment equipment, small wastewater treatment stations, and other facilities, enhancing their total nitrogen removal capacity.
3. Nitrogen-Containing Industrial Wastewater Treatment: It is suitable for the removal of total nitrogen pollutants in nitrogen-containing industrial wastewaters such as those from photovoltaic manufacturing, rare earth mining, tanning, pharmaceutical industry, and petrochemical industry. /4. Natural Water Body Restoration: It is suitable for improving surface water quality, eliminating black and odorous water bodies, and repairing nitrate-contaminated groundwater. It can be applied to processes such as constructed wetlands, ecological tree ponds, bank slope pollution interception, and infiltration reaction grids.
