Embodiment Construction

[0014] Such as figure 1 and figure 2 As shown, a method for treating sewage by annular contact oxidation reaction is characterized in that the sewage is first mixed with a flocculant, and then ozone air is injected into the sewage through a jet tube to mix with a pressure above 0.15 MPa, and then mixed. The mixture is mixed in the circulation mixer at a pressure greater than normal pressure, so that the mixture also forms bubble upwelling and waterfall impact mixing in the circulation mixer, so that a certain amount of ozone dissolves and adheres to the flocculated In the sewage of the agent, it is released again, which greatly improves the full contact time and contact area between ozone and organic matter and reducing pollutants in sewage. The above-mentioned mixed liquid uses a reflux device to control a certain amount of reflux to improve the reaction efficiency. The reflux device is used to circulate the reaction liquid multiple times and contact the reaction gas multip...

Abstract

A method for sewage disposal with ring-shaped contact oxidation reaction firstly mixes sewage with a flocculating agent, then ejects ozone air into the sewage for mixing by a jet pipe with pressure more than 0.15 MPa, mixes the mixture in a circulating mixer under a pressure more than standard atmosphere pressure, controls certain quantity of reflux to the mixing fluid with a reflux device, increases the reaction efficiency, and finally the sewage mixing fluid settles to finish the disposal process, and the flocculating agent is diatomite. The method and device for sewage disposal with ring-shaped contact oxidation reaction are simple, and the device has small covering area, small amount of electricity and medicaments consumption, small amount of investment, short construction time, low operation cost, and small amount of treated residual water, sludge and residue.

Description

Technical field: [0001] The utility model belongs to a method and a device for treating sewage, in particular to a method and a device for treating sewage by an annular contact oxidation reaction. Background technique: [0002] There are many disadvantages in the current sewage treatment process and equipment: complex process, huge equipment, large land occupation, high energy consumption, many types of medicines, and secondary pollution, which may not necessarily reach stable discharge standards in the end; Moreover, the investment is large, the construction time is long, the operating cost is high, and the maintenance process is complicated, which causes the users to be overwhelmed. Therefore, it is necessary to study new methods and equipment. Invention content: [0003] In view of the defects in the prior art, the object of the present invention is to provide a method and device for effectively treating sewage which can overcome the above defects. [0004] The techni...
