Benefits of technology

This patented technology allows for better treatment efficiency by creating different areas within one unit called an oxidative zone where bacteria break down organics while also allowing them to absorb ammonium or other nutrients from contaminated waters. Additionally, this design uses a special material made up mostly of sulfate instead of traditional charcoal to achieve effective removal of harmful substances such as phosphorus compounds (P), chlorine gas, etc., without requiring high maintenance costs associated therewith. Overall, these technical improvements improve the performance and effectiveness of biological filters designed specifically target specific types of impurities found at various locations throughout our country's drinking supply system.

Problems solved by technology

This patented technical solution described by this patent relates to improving the performance of wastewater purifying systems used on smaller scales where traditional methods may result in excessive power usage due to their lack of sufficient activity towards reducing nitro compounds. Existing solutions involve adding more expensive chemicals like bauxite or activating biofilm growth, resulting in increased operating expenses and difficulty in maintaining efficient treatments over time.

Abstract

The invention relates to the technical field of sewage treatment, and discloses a ventilation type deep denitrification biological filter device and a treatment method thereof. The device comprises a cavity, and a surface substrate layer, a nitrification filler layer, a plant slow-release carbon source layer and a denitrification filler layer are sequentially arranged in the cavity from top to bottom, wherein an opening is formed in the side wall, located at the plant slow-release carbon source layer, of the cavity; a water inlet pipe is laid in a sand soil layer; a ventilation pipe is laid at the lower part of the nitrification filler layer; and a water outlet pipe is laid at the lower part of the denitrification filler layer, and a water outlet of the water outlet pipe is higher than the top of the plant slow-release carbon source layer. The device is compact in structure, so that the biofilter has a simple operation and maintenance process, stable effluent quality and certain impact resistance while performing efficient and low-consumption denitrification.
