Septic tank (huàfènchí) is a device for treating excrement, filtering and settling it. Its principle is that the solidified substance decomposes at the bottom of the pond, and the upper hydrate enters the pipeline and flows away, thus preventing the pipeline from being blocked and giving the solidified substance (garbage such as feces) enough time to hydrolyze. Septic tank refers to a small treatment structure that precipitates domestic sewage and anaerobically digests sludge.
process flow
Septic tank is a treatment equipment that uses the principles of sedimentation and anaerobic fermentation to remove suspended organic matter from domestic sewage. A baffle is arranged in the high-efficiency corrugated FRP fertilizer device, and the holes on the baffle are staggered up and down, so that short flow is not easy to form, and the whole lower tank body is divided into three parts; A primary anaerobic chamber, a secondary anaerobic chamber and a clarification chamber, wherein the bottoms of the primary anaerobic chamber and the secondary anaerobic chamber are communicated, and MDS special filler is added inside.
This separation reduces the contact time between sewage and sludge, so that acid fermentation and alkali fermentation do not interfere with each other. At the same time, the existence of filler increases the contact surface area between sewage sludge and anaerobic bacteria, which greatly improves the reaction efficiency.
