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

　　The room has a first and second-grade anaerobic compartment with their bottoms interconnected, 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.

A septic tank is a treatment facility that utilizes sedimentation and anaerobic fermentation to remove suspended organic matter from domestic wastewater, and it is classified as a primary transitional treatment structure. Domestic wastewater contains a large amount of feces, paper fragments, pathogenic parasites, etc. The concentration of suspended solids ranges from 100 to 350 mg/L, with organic matter concentration

COD levels range between 100 to 400 mg/L, with the suspended organic matter concentration (BOD5) being between 50 to 200 mg/L. Sewage entering the septic tank undergoes 12 to 24 hours of sedimentation, removing 50% to 60% of suspended solids. The sludge settled out is then decomposed through anaerobic fermentation for over 3 months, causing the organic matter in the sludge to break down into

Stable inorganic matter, easily converts raw sludge into stable mature sludge, alters the sludge structure, and reduces its moisture content. Regularly remove and transport sludge for landfilling or use as fertilizer. Requirement: The calculated volume of the sedimentation and decomposition sections of the septic tank should comply with the "Design Standards for Building Water Supply and Drainage."

The "Code for Design of Building Services Engineering Systems" (GB50015-2003) Article 4.8.4 to 4.8.7 determines. The retention time of wastewater in the septic tank should be between 12h to 36h. For wastewater treatment systems without sludge disposal, the volume of the septic tank should also include the storage volume for sludge.
