Problems solved by technology

[0003] There are many ways to treat sewage. At present, the biosorption method is widely used, which has high adsorption and decontamination efficiency and is widely used. However, most of the current biosorption methods rely on adsorption of biochar for adsorption, but most of the biochar is not recycled. And it is directly put into the sedimentation tank for precipitation, its adsorption efficiency is too low, and it cannot guarantee that the suspended solids in the water can be quickly adsorbed and precipitated, resulting in increased cost and low adsorption efficiency

Abstract

The invention discloses an efficient and energy-saving device for treating sewage with charcoal. The device mainly comprises a first sedimentation tower, a second sedimentation, a sterilization tank and a backwash tank, wherein the first sedimentation tower comprises a mud scraping mechanism, a filtering screen and an impurity cleaning mechanism; the second sedimentation comprises an adsorption tube, a second rotating rod for stirring and pushing wastes, and a waste tank mounted at the bottom of the second sedimentation tower; a plurality of progressive fan blades are mounted on the second rotating rod; the second sedimentation tower communicates with the waste tank through a baffle plate which is arranged at the bottom of the second sedimentation tower; the adsorption tube is an arch-shaped pipeline which is composed of a plurality rows of U-shaped tubes in a communication manner; the sterilization tank comprises a plurality of sterilization rods which are arranged at the top and thebottom of the sterilization tank in a staggered manner and a water outlet tube which is arranged on a side surface of the sterilization tank; and the backwash tank comprises a water pump and an air pump. The device is high in sewage treatment efficiency, low in cost and applicable to wide popularization.

Description

technical field [0001] The invention relates to the technical field of sewage biological treatment, in particular to a high-efficiency and energy-saving sewage treatment device using biochar. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. [0003] There are many ways to treat sewage. At present, the biosorption method is widely used, which has high adsorption and decontamination efficiency and is widely used. However, most of the current biosorption methods rely on adsorption of biochar for adsorption, but most of the biochar is not recycled. And it is directly put into the sedimenta...
