Working principle of septic tank
Septic tank is a treatment equipment which uses the principle of sedimentation and anaerobic fermentation to remove suspended organic matters in domestic sewage. The high-efficiency corrugated glass toughened dung machine is equipped with a partition board, the holes on the partition board are staggered up and down, which is not easy to form short flow, and the whole lower tank body is divided into three parts; the first stage anaerobic chamber, the second stage anaerobic chamber and the clarification chamber are connected with the bottom of the first stage and the second stage anaerobic chamber, and the inside is added with "MDS special packing". Such separation reduces the contact time between sewage and sludge, and makes the two processes of acid fermentation and alkaline fermentation not interfere with each other. At the same time, the presence of fillers increases the contact surface area between sewage sludge and anaerobic bacteria, and greatly improves the reaction efficiency.
