Movable adsorption equipment and method for treating waste water

Abstract

The invention relates to movable adsorption equipment for treating waste water. The equipment comprises an adsorption bed inside which an adsorption material is arranged, wherein the lower part of the adsorption bed is provided with a waste water inlet pipe, while the upper part is provided with a purified water outlet pipe; the main body of the adsorption bed has a cylindrical structure; the topof the cylindrical structure is provided with an adsorption material feed inlet which is connected with a storage bin for storing the absorption material through a feeding machine; the lower part of the cylindrical structure is communicated with an inverted conical structure; the lower part of the inverted conical structure is communicated with a cavity; and the cavity is connected with a discharging machine. The technical problems of the need of stopping fixed-bed water treatment and adsorption equipment for replacing the absorbing material, the increase of equipment and the reduction in theutilization ratio of the equipment in the prior art are solved. The movable adsorption equipment and a method for treating the waste water have the advantages of continuous operation, no need of stopping the equipment for replacing the absorbing material and high efficiency.

Description

technical field [0001] The invention relates to a water treatment device and a water treatment method using the device, in particular to a mobile adsorption device and a method for treating waste water. Background technique [0002] Water is an important natural resource for human survival. For industrial wastewater and domestic sewage, it needs to be treated before being discharged into nature or reused. Commonly used water treatment methods are: sediment purification method, hard water softening method, deionization method, reverse osmosis method, ultra-purification method, distillation method, ultraviolet disinfection method, biochemical method, etc. The active material adsorption method is a common method of water treatment. Due to the unique structure of the active material such as activated carbon and activated coke, which has a developed void structure, a huge specific surface area and a special surface functional group, it has good adsorption properties. It can eff...
