Sewage treatment method and equipment thereof

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 pot, the top center of which is provided with a materials feeding mouth and the base center of which is provided with a materials discharge mouth. The pot is filled with active carbon. The two sides of the pot top are provided with outlet branches, an end of which is an outlet mouth and the other end of which is connected with a plurality of ring-shaped outlet pipes in the pot. The ring-shaped outlet pipes are distributed with outlet holes. A side of the pot lower part is provided with inlet branches, an end of which is an inlet mouth and the other end of which is connected with a plurality of ring-shaped inlet pipes in the pot. The ring-shaped inlet pipes are distributed with inlet holes. The other side of the pot lower part corresponding to the inlet mouth is disposed with a sewage discharge pipe and the other end is connected with a plurality of ring-shaped inlet pipes in the pot. The invention is capable of improving quality of waste water and sewage treatment and reducing electricity consumption thereof.

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 implementing the above 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 dealing with...

AI Technical Summary

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
