Use method of sewage filtering tank with activated carbon powder adding function

Abstract

The invention discloses a use method of a sewage filtering tank with an activated carbon powder adding function. The method comprises five steps of powder blanking, sewage filling, shaking, feeding, discharging and secondary shaking. The step process is simple, a power mechanism and a shaking mechanism are used for shaking a rubber hose and a U-shaped pipe above a material distribution cavity, andthus the blockage of powder in a pipeline is further prevented; when the device is stationary, a material distribution cavity is deflected, and activated carbon powder conveyed from a material storage cavity is received by the material distribution cavity; under the driving of the power mechanism, the material distributing cavity rotates anticlockwise around a rotating shaft, activated carbon powder in the material distributing cavity is fed, the material distributing cavity extrudes the rubber hose in the rotating process, discharging of the powder in the pipeline is prevented, and then quantitative feeding of the activated carbon is achieved, and the use method is suitable for popularization.

Description

technical field [0001] The invention belongs to the technical field of environmental protection machinery, in particular to a method for using a sewage filter tank with the function of adding activated carbon powder. Background technique [0002] Powdered activated carbon is made of high-quality wood chips, coal, charcoal, fruit shells, etc., and processed through a series of fine processes. Powdered activated carbon has the advantages of fast filtration speed, good adsorption performance, economical and durable, etc. Due to its excellent pore structure, powdered activated carbon is widely used in tap water treatment and wastewater treatment because of its strong adsorption and decolorization capabilities. Powdered activated carbon has good adsorption performance, good chemical stability, and a specific surface area as high as 1000~1500m3 / g. It is a porous hydrophobic adsorbent and is widely used in mineral processing, smelting, steel, chemical and other industries. Activate...

AI Technical Summary

Problems solved by technology

Activated carbon filtration is a water filtration process using activated carbon as a filter material. The surface area of ​​activated carbon per gram is 500-1700m3, and the true specific gravity is 1.9-2.1. Due to its porosity, it can absorb fine substances in various liquids during filtration, and is often used in water Decolorization, deodorization, dechlorination, removal of organic matter and heavy metals, removal of synthetic detergents, bacteria, viruses and radioactive pollutants in the treatment are also commonly used in the tertiary treatment of wastewater, but there are the following problems in the process of adding powder activated carbon , such as the amount of addition is not easy to control, the delivery pipeline is easy to block, and maintenance is troublesome, etc. Therefore, there is an urgent need for a method of using a sewage filter tank with the function of adding activated carbon powder that can be quantitatively distributed and the delivery pipeline is not easy to block, so as to overcome the existing activated carbon. Many problems in the process
