Above-mentioned biological fermentation process Sewage treatment systems, the left and right sides contour dimension of described tank body and up and down contour dimension equate.

Above-mentioned biological fermentation process Sewage treatment systems, described material adopts stalk, leaf, weeds or Vegetrable fibre material.

Above-mentioned biological fermentation process Sewage treatment systems, the quantity of described fermentor tank tank body are a plurality of, and each fermentor tank tank body is end to end.

The utility model adopts rotary-type sewage treatment pot, after the biomass fertilizers such as adding stalk or life waste material, under the effect of biological bacteria, cooperates sewage to carry out biological fermentation and physical filtering simultaneously in tank body; In sewage treatment process, tank body slowly rotates along axis, and material overturns to the center, stirs, and the biological bacteria activity is high, temperature of reaction is high, and sewage, waste material ferment fast fully, and efficient energy-saving can normally use at temperature lower winter.

The utility model can realize that sewage handles automatically, the water after the processing become can contact in water, byproducts such as mud, waste material can directly be used as organic fertilizer and use, and can not produce secondary pollution; Apparatus for treating sewage is three-dimensional to be provided with, and it is little to take up room.

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model left view.

The component label is respectively in the accompanying drawing: 1. tank body; 2. axis; 3. main body rack; 4. charging opening; 5. discharge port; 6. ring gear; 7. filter screen; 8. stirring flange; 9. annular top surface; 10. frustum cone cylinder; 11. pole; 12. bearing support; 13. ostium excurrens; 14. step-down gear; 15. gear; 16. motor; 17. material.

Embodiment

Consult embodiment illustrated in fig. 1, fermentor tank tank body 1 is tubular, horizontal supporting, the tank body side end face is connected with the frustum cone cylinder 10 of the ring-like end face 9 in both sides by both sides, two end face intermediary perforates are respectively charging opening 4 and discharge port 5, charging opening is fixedlyed connected with axis 2 by pole 11 respectively with discharge port, axis on the main body rack 3 at tank body two ends, is provided with some sewage ostium excurrenses 13 at axis 2 outer walls of opening for feed one side by bearing support 12 swivel bearings; In conjunction with shown in Figure 2, on the frustum cone cylinder of described tank body one side ring gear 6 is set, driving toothed gear 15 engagements on ring gear and the step-down gear 14, motor 16 drive speed reducer drive the fermentor tank tank body and rotate.Inner tank wall is provided with and stirs flange 8, described stirring flange face is vertical with wall, described stirring flange tilts along same direction, it is opposite with the tank body sense of rotation to stir the flange vergence direction, water inlet one side main body rack 3 is the liftable type, and this side stand raises when discharging, and tank body is when inlet side is rotated counterclockwise simultaneously, material 17 is the state of stirring, also constantly carries to a side in fermentor tank inside, be beneficial to material and draw off.Organic materialss such as the interior stalk of tank body are stacked level height and are reached 1/2 or 1/3 of tank body vertical height.

Adopt the bar shaped filter screen that is provided with at interval on the utility model tank body intermediary barrel, filter screen order number is 10～40 orders.In the fermentor tank operation process, sewage and biomass material be through a series of biological respinses, and sewage changes the bar shaped filter screen 7 of cleaning water through the tank body bottom surface into and slowly permeates discharge then; On the bar shaped filter screen sealing plate can be set, but the sealing plate time opening is to open a sluice gate and draw out some water.In the winter time, when outside air temperature was low, lagging material can be laid in the tank body outside, and the biological fermentation effect is better.In the practical application, need on the lagging material of tank body bottom surface, reserve water port.

The utility model fermentor tank tank body volume is big, rotates slowly, can carry out the mixed fermentation processing to large amount of sewage and waste material continuously, tank body interior reaction temperature height, biological bacteria is active high, efficiently solves when temperature is low in the winter time, is difficult for the defective of using ordinary method to dispose of sewage.The radius of the left and right sides contour dimension of tank body and contour dimension up and down is identical, so that the material reaction space of tank interior is approaching circular, it is stressed rationally to help the large size tank body, also is easy under the equivalent material parameter, guarantee the intensity of tank body, and take the insulation measure easily.

High-temperature aerobic fermentation can take place in the organic materials fermentation in the fermentor tank of the present utility model, and organism is oxidized to water and carbonic acid gas; Organic substance nitrogen in biological bacteria and the material and nitrogenous source etc. produce phenolic hydroxy group, carboxylic compound, and in fermentation deuterogenesis condensation reaction, generate the macromole organic monoacid, as humic acid, amino acid etc.; Metallic cation generation permutoid reaction in these macromole weak acid and the material, generation is insoluble in the inert substance of water, i.e. and " heavy metal passivation ", the heavy metal after the passivation is increased by the difficulty of farm crop and animal absorption, alleviated murder by poisoning to farm crop, and to the harm of HUMAN HEALTH.The utility model is not only applicable to the denitrogenation processing of high nitrogen sewage, also is applicable to high-concentration sewage or contains the sewage deoxidation treatment of profit; Whole mechanism is simple, and use cost is low, and is easy to operate, all can use throughout the year; For sewage is carried out advanced treatment, can adopt the end to end series connection of two or more fermentation tank bodies to use in the practical application, wastewater treatment efficiency is better.
