Problems solved by technology

[0005] The purpose of the present invention is to provide a kind of waste water treatment device that is used for sweet potato processing and cleaning, by arranging primary settling pond, anaerobic pond, anoxic pond, aerobic pond, MBR pond and efficient settling pond, realize the effective treatment to waste water, Significantly reduce the COD value, ammonia nitrogen value and total phosphorus value of potato wastewater, and improve the wastewater treatment effect. The effluent discrimination module judges the effluent quality based on the rating data information. The quality of discharged wastewater can effectively avoid pollution and potential harm to the water environment. The self-adjusting chemical box enables the stable output of flocculants. The treatment effect of wastewater solves the problem that the existing technology can only remove solid impurities in potato wastewater, and the treatment effect is poor. It cannot effectively reduce the COD value, ammonia nitrogen value and total phosphorus value of potato wastewater, and it cannot detect and judge the effluent, and it will still cause Problems that pose great harm to the water environment

Embodiment 1

[0044] like Figure 1-6 As shown, the present invention proposes a waste water treatment device for processing and cleaning potato, including a primary sedimentation tank 1, an anaerobic tank 2, an anoxic tank 3, an aerobic tank 4, an MBR tank 5 and a high-efficiency sedimentation tank 6. The waste water enters the primary sedimentation tank 1, and the supernatant in the primary sedimentation tank 1 enters the anaerobic tank 2, the anoxic tank 3, the aerobic tank 4, the MBR tank 5 and the high-efficiency sedimentation tank 6 in turn. The PH in the anaerobic tank 2 The pH value is 6.8-7.2, the pH value in the anoxic tank 3 is 6.5-7.5, the pH value in the aerobic tank 4 is 7.5-8.5, and the anaerobic tank 2 coexists with acid-producing bacteria and methanogenic bacteria; The dissolved oxygen in pool 2 is less than 0.2 mg / L, the dissolved oxygen in anoxic pool 3 is less than 0.5 mg / L, and the dissolved oxygen in aerobic pool 4 is 2-4 mg / L; The nitrifying liquid return pipe commun...

Embodiment 2

[0059] like Image 6 and Figure 9-10 As shown, the difference between this embodiment and Embodiment 1 is that the top end of the lifting and stirring shaft 81 extends into the installation and fixing box 12, and the installation and fixing box 12 is mounted with a rotating intermediate shaft 14 through a bearing, and the rotating intermediate shaft 14 is away from the installation and fixed. One end of the box 12 extends into the self-adjusting medicine box 7, and the top of the lifting and stirring shaft 81 is connected with the rotating shaft 14 through a bevel gear. The self-adjusting medicine box 7 is provided with a medicine storage room 71 and a material receiving room 74, and The medicine storage chamber 71 is located above the receiving chamber 74. The medicine storage chamber 71 and the receiving chamber 74 communicate with each other through the communication port 75. The medicine storage chamber 71 is rotatably installed with a rotating fragment shaft 76 through a...

Embodiment 3

[0062] like Figure 6-8 As shown, the difference between this embodiment and Embodiment 1 and Embodiment 2 is that a feeding port 72 is installed on the top of the self-regulating medicine box 7, and flocculant or precipitant can be added to the box through the feeding port 72, and the feeding chamber 74 A concave inclined seat 73 is installed inside, the bottom of the concave inclined seat 73 is a vertical section, the vertical section extends downward into the lower material box 77, and the vertical section is provided with a lower material channel 79 and a storage groove 713, The opening and closing cylinder 714 is fixedly installed in the receiving groove 713, and the opening and closing block 712 is installed on the extending end of the opening and closing cylinder 714. When the opening and closing block 712 is closed, the opening and closing block 712 blocks the entry of the unloading channel 79 into the unloading channel 79 to block it. in a smooth state;

Abstract

The invention belongs to the technical field of sweet potato processing, and aims to solve the problems that only solid impurities in sweet potato wastewater can be removed, the treatment effect is poor, the COD (Chemical Oxygen Demand) value, ammonia nitrogen value and total phosphorus value of the sweet potato wastewater cannot be effectively reduced, the effluent cannot be detected and judged, and great harm is still brought to the water environment in the prior art. Comprising a primary sedimentation tank, supernate in the primary sedimentation tank sequentially enters an anaerobic tank, an anoxic tank, an aerobic tank, an MBR tank and a high-efficiency sedimentation tank, supernate in the high-efficiency sedimentation tank enters a detection and discrimination tank, the detection and discrimination tank detects effluent, and a self-adjusting agent box is arranged at the top of the high-efficiency sedimentation tank; according to the method, the COD value, the ammonia nitrogen value and the total phosphorus value of the sweet potato wastewater can be remarkably reduced, the quality of the discharged wastewater can be guaranteed, pollution and potential hazards to the water environment are effectively avoided, and the treatment effect on the sweet potato wastewater is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of potato processing, in particular to a waste water treatment device used for potato processing and cleaning. Background technique [0002] A large amount of waste water will be produced in the process of potato starch processing. It is estimated that processing one ton of potato produces about four to six tons of potato waste water. The potato waste water is mainly composed of three parts of waste water. The amount of waste water is large, the degree of pollution is low, and the content of organic pollutants is not high. The second is the waste water produced by elutriating starch during the production process of potato starch. This part of the waste water has a high degree of pollution and a very high content of organic pollutants. The third is the washing of the production workshop. The pollution degree of the wastewater generated from the floor is between the above two. The comprehensive wastewater form...
