Mud and water mixture
The traditional septic tank has a history of over a hundred years. Its technological approach involves the contact between wastewater and sludge. The deposited sludge undergoes digestion and degradation to produce biogas, carbon dioxide, and other digestion gases. The buoyant action of the digestion gases disturbs the sludge, and this disturbance allows the sludge to...
The mixed biofilm is more thorough, aiding in digestion and degradation. However, the bottom sludge rises with the digestion gas, only to settle back down once the bubbles escape. This cyclic rising and settling of sludge re-contaminates the wastewater.
In the technological mode where septic tank wastewater and sludge come into contact and mix, the sedimentation and effluent water quality of the septic tank are affected. To improve the sedimentation effect and effluent water quality, the wastewater retention time needs to be extended, typically ranging from 12 to 24 hours.
Three-phase separation
The three-phase separation septic tank technology retains the advantages of sludge and water mixture in traditional septic tanks, and introduces a technique for separating "sewage, sludge, and digestible gas" into three phases. It includes a three-phase separation device at the outlet of the septic tank, separating the sludge and digestible gas from the sewage treatment process.
Avoid interference from air floatation phenomena in wastewater treatment. The sedimentation tank at the outlet end conforms to the technical standards of horizontal sedimentation tanks, with a wastewater sedimentation time of 2 hours or less.
Technical Comparison
The septic tank's volume is composed of wastewater and sludge volumes. In a three-phase separation septic tank, the wastewater retention time is 4-6 hours, compared to 12-24 hours in a sludge-water mixed septic tank. By shortening the wastewater retention time, the effective volume is saved, which can store more wastewater.
Clay.
Septic tanks are treatment equipment that utilizes sedimentation and anaerobic fermentation principles to remove suspended organic matter from domestic wastewater. The high-efficiency corrugated fiberglass septic tank is internally equipped with baffles, with the holes on the baffles misaligned vertically, 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-grade anaerobic compartment with their bottoms interconnected, internally fitted with "MDS Special Type Filler." This partitioning 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, greatly...
