The function of a septic tank

Septic tanks are basic sludge treatment facilities and also pre-treatment facilities for domestic wastewater, serving the following functions:

1. Ensure the cleanliness of residential community environments, preventing the spread of domestic wastewater and pollutants.

2. Eliminate mosquito and fly eggs in the anaerobic digestion environment of septic tanks.

3. Temporary storage of sludge, anaerobic digestion of organic sludge, matured organic sludge can be used as agricultural fertilizer.

4. Preliminary treatment of domestic wastewater (primary treatment), sedimentation of impurities, and hydrolysis of macromolecular organic matter into smaller organic molecules such as acids and alcohols, to improve subsequent wastewater treatment.

Septic tanks are treatment devices that utilize sedimentation and anaerobic fermentation principles to remove suspended organic matter from domestic wastewater. The high-efficiency corrugated fiberglass septic tanks are equipped with baffles, which have holes misaligned vertically and horizontally, preventing short-circuiting and dividing the entire tank into three sections: primary anaerobic chamber, secondary anaerobic chamber, and clarification section.

　　The room features a first and second-level anaerobic compartment with their bottoms connected, internally fitted with "MDS Special-Type Filler." This separation reduces the contact time between wastewater and sludge, ensuring that the acidic fermentation and alkaline fermentation processes do not interfere with each other. Additionally, the presence of the filler increases the contact surface area between wastewater and sludge, significantly...

Enhanced response efficiency.
