Device for sewage treatment and treatment method thereof

Abstract

The invention discloses a device for sewage treatment. The device comprises a grating well, an adjusting tank, a hydrolysis acidification tank, an aerobic biological tank, a sedimentation tank and a clean water tank which are sequentially connected through water pipes, wherein a detachable grating net is arranged at the front end of the grating well; a blow-off pipe is arranged at the bottom of the sedimentation tank; one end of the blow-off pipe is connected into the hydrolysis acidification tank for backflow, and the other end is connected with an external sludge tank; a solid-liquid separation device is arranged in the sludge tank; a solid-liquid separation device is used for enabling supernatant liquid to flow back into the adjusting tank; the other part of solid is prepared into a mudcake through a filter press and conveyed to the outside; fans are arranged on the adjusting tank, the hydrolysis acidification tank and the aerobic biological tank. The device has the advantages thatthe structure is simple, the use is convenient, the effect of purifying and separating impurities is good, water in the device can be fully purified through backflow of water in the device, no drop of water is wasted, the effect of a pollution pool is improved, the device not only has a precipitation effect, and water resources are greatly saved.

Description

technical field

[0001] The invention relates to the field of sewage treatment, in particular to a device for sewage treatment and a treatment method thereof. Background technique

[0002] Most beverage companies will produce a large amount of sewage after making beverages, and the production sewage discharged for them is mixed sewage, etc. According to the relevant national discharge standards, etc., after treatment, it will reach the third-level discharge standard and meet the requirements of "Comprehensive Wastewater Discharge" The discharge standard of the urban pipe network in the "Standard" is allowed to discharge. Although the existing treatment device can achieve the environmental protection standard through the process, it consumes a lot of manpower and material resources, and in terms of saving, a large amount of water will still be lost. Contents of the invention

[0003] The present invention mainly solves the problems of how to make the volume of the existing s...

Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with the accompanying drawings: figure 1 As shown, a device for sewage treatment is characterized in that the device includes a grid well 1, a regulating tank 2, a hydrolytic acidification tank 3, an aerobic biological tank 4, a sedimentation tank 5, Clear water pool 6, the front end of the grid 1 well is provided with a detachable grid 7, the bottom of the sedimentation tank 5 is provided with a sewage pipe 8, and the sewage pipe 8 is connected to the sludge pool at the bottom through a three-way valve 12. 9. The other end returns the sewage to the hydrolysis acidification tank 3 through the return pump 15, and the solid-liquid separation device 10 is arranged in the sludge tank 9, and the solid-liquid separation device 10 returns the supernatant to the liquid through the return pump 15. The regulating pond 2 is waiting for further treatment, and the other part of the solid waste is sent to the outs...
