Product Description

Operating Process:

The primary anaerobic chamber serves to accept fresh feces, anaerobically ferment, decompose, and separate the layers, consisting of top scum, middle liquid, and bottom sludge. It also captures and settles parasitic eggs.
 

The secondary anaerobic chamber continues to capture and settle parasitic eggs, facilitates deeper anaerobic fermentation, and increases the concentration of free ammonia.

The disinfection and egg-killing clarification tank primarily serves the purpose of clarification, ensuring that the discharged wastewater is environmentally safe.
 

Domestic wastewater enters the septic tank through the upper inlet, settling within the tank. As the wastewater flows through the baffles in the septic tank and is treated using the principles of septic tank theory, and filtration, it extends the retention time in the tank. The contact and degradation time between the wastewater and settled sludge is prolonged, and the wastewater comes into contact with the microorganisms in the filter. The organic pollutants in the wastewater are biologically broken down and digested, effectively achieving the purification and treatment of the wastewater.
