AI Technical Summary

Technical Problem

Existing non-powered septic tanks have a weak effect on purifying nitrogen and phosphorus nutrients, and septic tanks are prone to leakage, making large-scale production impossible. Furthermore, they fail to effectively remove harmful microorganisms from domestic sewage.

Method used

The anaerobic and micro-aerobic trickling filtration domestic sewage purification tank is divided into multiple chambers by partitions. Combined with different packing layers and a ventilation system, it realizes anaerobic and aerobic biochemical reactions. It uses volcanic rock suspended packing, 15PPI filter cotton and three-dimensional mesh deaeration packing for multi-stage purification. With the help of non-powered wind caps and water distribution system, it achieves uniform distribution and full purification of sewage.

Benefits of technology

It effectively removes nitrogen and phosphorus nutrients from wastewater, improves purification efficiency, reduces the risk of leakage, enables large-scale production, ensures the elimination of harmful microorganisms, and avoids environmental pollution and odor generation.
