Problems solved by technology

[0004] Therefore, the existing sewage treatment technology requires that the water quality must have good biodegradability, and must have 24-hour aeration and oxygen supply, which has complicated system management, high operating costs, and prone to bacterial death and loss due to improper maintenance. The problem of purification effect

Embodiment 1

[0043] The present embodiment provides a kind of sewage treatment method, and it comprises the following steps successively:

[0044] (1) Pass the sewage into the degradation zone, and degrade it under the irradiation of UV light and the catalysis of titanium dioxide;

[0045] (2) Pass the degraded sewage into the sedimentation area for sedimentation treatment;

[0046] (3) Pass the supernatant of the sewage after sedimentation treatment into the filter area for filtration treatment, so that the filtered effluent can meet the water quality standard for reclaimed water

[0047] In order to improve the effect of sedimentation treatment, preferably, PAC and PAM are also added during the sedimentation treatment in step (2), so that the sedimentation effect can be better improved through the adsorption of PAC and PAM.

[0048] Meanwhile, the duration of the sedimentation treatment in step (1) is preferably 1-2 hours.

[0049] Its workflow is as follows figure 1 As shown, the sew...

Embodiment 2

[0051] Such as figure 2 As shown, this embodiment provides a sewage treatment device based on the sewage treatment method in Example 1, which includes a degradation chamber 101 , a sedimentation chamber 201 and a filtration chamber 301 arranged in sequence.

[0052] The degradation chamber 101 is provided with a water inlet 103 , a titanium dioxide catalyst and several UV lamps 102 ;

[0053] The settling chamber 201 is provided with a central guide pipe 202, an umbrella-shaped reflector 204, an overflow weir and a conical sedimentation bucket 203; the conical sedimentation bucket 203 is arranged at the bottom of the sedimentation chamber 201; the central guide pipe 202 and The umbrella-shaped reflectors 204 are all arranged above the conical sedimentation bucket 203 , and the umbrella-shaped reflectors 204 are arranged below the water outlet end of the central draft pipe 202 .

[0054] Wherein, preferably, the conical sedimentation bucket 203 , the umbrella-shaped reflector 2...

Abstract

The invention provides a sewage treatment method and a sewage treatment device, belonging to the technical field of sewage treatment. The sewage treatment method includes: (1) passing the sewage into the degradation zone, and performing degradation treatment under the irradiation of UV light and the catalysis of titanium dioxide; (2) passing the degraded sewage into the sedimentation zone for sedimentation treatment; (3) The supernatant of the sewage after the sedimentation treatment is passed into the filter area for filtration treatment, so that the filtered effluent can meet the water quality standard for reclaimed water. The sewage treatment device includes: a degradation chamber, a settling chamber and a filtering chamber arranged in sequence. The sewage treatment method and the sewage treatment device generate OH and O through a titanium dioxide catalyst under the action of UV light. 3 , so that the sewage treatment method and sewage treatment device can not be limited by water quality; at the same time, it realizes the integrated treatment of degradation and sterilization, so it simplifies the sewage treatment technology, reduces the operation cost, and improves the sewage treatment effect.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a treatment method and a treatment device for organic industrial waste water and sewage which are difficult to biodegrade. Background technique [0002] At present, the sewage treatment equipment on the market is mainly based on the traditional biological treatment method, which is mainly based on microorganisms, and uses biodegradation to achieve the purpose of purifying and treating sewage. [0003] However, the existing sewage treatment technology has strong limitations, and it has high requirements on water quality. The general water quality requirements are: influent CODcr≤800mg / L, and BOD5 / CODcr≥0.3; among them, CODcr is the chemical oxygen demand measured by using potassium dichromate (K2Cr2O7) as the oxidant, that is, the dichromate index; BOD5 It is an important indicator that uses the amount of dissolved oxygen consumed by microbial metabolism to indirectly in...
