AI Technical Summary

Technical Problem

Existing building septic tanks are prone to accumulating biogas and odors, leading to safety hazards and environmental pollution. In particular, the odor is overwhelming when septic tanks are cleaned in commercial buildings, affecting the environment.

Method used

Branch pipes are installed inside the septic tank and connected to the ventilated static pressure box. A biogas detector and a blower are provided. The biogas concentration is monitored by a controller. When the preset value is reached, the gas is automatically ventilated. The drug is evenly distributed through the dosing pipe, avoiding manual operation.

Benefits of technology

It enables automatic monitoring and emission of biogas concentration in septic tanks, reducing safety hazards and odor spread, and improving the efficiency and effectiveness of drug administration.
