Sewage treatment equipment

Abstract

A method for sewage treatment contacts the sewage with active carbon. The sewage flow speed is no bigger than 0.05m / min and the sewage flux, the sewage flux on per meter active carbon sectional area is no bigger than 1m3 / h, wherein the granular diameter of the active carbon is no bigger than 20 meshes. The invention relates to an active carbon absorbent bed, the top of which is provided with an open structure and the base of which is provided with a tapered structure and also with over one discharge mouthes. The bed is filled with active carbon with the granular diameter no bigger than 20 meshes. The four sides and center of the bed top are provided with a catch basin, the near-bed side of which is a outlet branch and the lower level of the outlet branch is on the same horizontal line of the lower level of the catch basin. The lower end of the bed is connected with a plurality of inlet pipes. The inlet pipes are distributed with inlet holes. An end of the inlet pipes is connected with the inlet branch passing through the bed wall and the other end of the inlet pipes is connected with the sewage valve passing through the bed wall. The active carbon asborbent bed is provided with a discharge washing pipe in the lower center and the discharge washing pipe is provided with a spray nozzle.

Description

technical field [0001] The invention belongs to the technical field of industrial waste water and urban sewage treatment, and in particular relates to a method for treating industrial waste water and urban sewage by adopting active coke. [0002] The invention also relates to a device for carrying out the above-mentioned method. Background technique [0003] At present, industrial wastewater and urban sewage are treated with facilities and equipment such as grilles, hydraulic screens, homogeneous tanks, primary sedimentation tanks, aeration tanks, secondary sedimentation tanks, and inclined tube sedimentation tanks, and various Chemicals are used for sedimentation, flocculation, air flotation, activated sludge, aeration, anaerobic, fermentation and other biochemical and physical chemical treatments. The shortcomings of the above-mentioned facilities and equipment are complex technology, large floor area, large power consumption, and operating costs. High, especially when de...

Problems solved by technology

[0003] At present, industrial wastewater and urban sewage are treated with facilities and equipment such as grilles, hydraulic screens, homogeneous tanks, primary sedimentation tanks, aeration tanks, secondary sedimentation tanks, and inclined tube sedimentation tanks, and various Chemicals are used for sedimentation, flocculation, air flotation, activated sludge, aeration, anaerobic, fermentation and other biochemical and physical chemical treatments. The shortcomings of the above-mentioned facilities and equipment are complex technology, large floor area, large power consumption, and operating costs. High, especially when dealing with industrial wastewater and waste liquid with high chemical oxygen demand (COD) value and complex composition, it is difficult to meet the specified standards

How to use activated coke to treat industrial wastewater, urban sewage, etc., so that the treatment of industrial wastewater, urban sewage, etc. reduces the area occupied, reduces power consumption, reduces treatment costs and investment costs, and improves the processing capacity and quality of industrial wastewater, urban sewage, etc. To meet increasingly higher environmental protection standards, there has been no report so far
