Due to the limitation of the buried sewage treatment device, the whole equipment space is small, and the dredging work is inconvenient; meanwhile, waste gas and toxic gas are arranged in the whole equipment, and the cleaning is seriously influenced. Therefore, after the existing underground sewage treatment equipment operates for a period of time, more than 70 percent of the equipment cannot operate due to the inconvenience of sludge cleaning.
Accordingly, the prior art is deficient and needs improvement.
SUMMERY OF THE UTILITY MODEL
The utility model mainly aims to provide a buried automatic dredging sewage treatment system, aiming at realizing automatic dredging of the sewage treatment system.
In order to achieve the purpose, the buried automatic dredging sewage treatment system provided by the utility model comprises a sewage treatment tank and a sludge sedimentation tank which are sequentially connected, wherein the sewage treatment tank is used for treating sewage, the treated sewage enters the sludge sedimentation tank, and clear water is discharged after the treated sewage is subjected to sludge sedimentation by the sewage sedimentation tank; a sludge collecting hopper is arranged below the sludge settling tank, a sludge discharge pump is arranged at the lowest point of the sludge collecting hopper, and the sludge discharge pump is connected with a control system of a sewage treatment system; the sludge pump is connected with a sludge discharge pipe, the sludge discharge pipe is connected with a sludge drying tank, a filter layer is arranged in the sludge drying tank, the sludge drying tank is further provided with a return pipe connected with the sewage treatment tank, and sewage after the sludge drying tank carries out drying treatment on the sludge flows back to the sewage treatment tank through the return pipe.
Preferably, the inclination angle of the mud collecting hopper is set to 45-60 °.
Preferably, the sludge pump is arranged as a submersible sewage pump.
Preferably, the filter medium in the filter layer comprises quartz sand and river sand.
Preferably, the sewage treatment tank and the sludge sedimentation tank are respectively provided with an access hole above.
Compared with the prior art, the utility model has the beneficial effects that: the sewage treatment pond is handled sewage and is carried to sludge sedimentation tank, and deposits such as silt in the sludge sedimentation tank are collected through the mud collection fill, then discharge to the sludge drying pond through the mud pump regularly to solve the silt deposit that whole sewage treatment facility long-term work produced, clear up the problem of difficulty, and then improve processing system's sewage treatment efficiency. The sewage treatment system has the advantages of simple structure, small occupied area and convenience in dredging, and has great use value for users with limited occupied area.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the structures shown in the drawings without creative efforts.
FIG. 1 is a schematic view of a sewage treatment system according to the present invention;
the implementation, functional features and advantages of the objects of the present invention will be further explained with reference to the accompanying drawings.
Detailed Description
Referring to fig. 1, the buried automatic dredging sewage treatment system provided by this embodiment includes a sewage treatment tank 1 and a sludge settling tank 2 which are connected in sequence, wherein the sewage treatment tank 1 is used for treating sewage, the treated sewage enters the sludge settling tank 2, and the sewage settling tank performs sludge settling on the treated sewage and then discharges clean water; a sludge collecting hopper 3 is arranged below the sludge settling tank 2, a sludge discharge pump 4 is arranged at the lowest point of the sludge collecting hopper 3, and the sludge discharge pump 4 is connected with a control system of a sewage treatment system; sludge pump 4 connects a sludge discharge pipe 5, sludge discharge pipe 5 is connected with a sludge drying pond 6, be equipped with a filter layer 7 in the sludge drying pond 6, sludge drying pond 6 still be equipped with one with the back flow 8 that sewage treatment pond 1 is connected, sludge drying pond 6 carries out the sewage after the mummification is handled to mud and passes through back flow 8 backward to sewage treatment pond 1.
It should be noted that the control system in this embodiment is an electronic control system commonly used in the prior art, and is used for controlling the sludge pump 4 to be opened at regular time for performing the sewage disposal operation, and the sludge pump 4 in this embodiment is configured as a submersible sewage pump. Specifically, this system during operation, outside sewage gets into sewage treatment pond 1, carries out conventional processing to sewage, and the sewage after the processing is carried to mud sedimentation tank 2 and is carried out sludge sedimentation, and the clear water after the sediment is discharged from mud sedimentation tank 2's clear water export. Sediment such as sludge in the sludge sedimentation tank 2 sinks into the collecting hopper, the collecting hopper is connected with the sludge discharge pump 4, the sludge discharge pump 4 is controlled by the control system to convey sludge in the collecting hopper to the sludge drying tank 6 through the sludge discharge pipe 5 at regular time, the sludge drying tank 6 is used for drying the sludge and filtering the sludge through the filter layer 7, and the filtered water is discharged into the sewage treatment tank 1 through the return pipe 8 again for circular treatment, so that the obtained clear water is discharged from the clear water discharge port.
Further, the inclination angle of the mud collecting hopper 3 is set to be 45-60 degrees, so that deposition of sediments such as sludge is facilitated, and the sediments are quickly pumped out.
Furthermore, the filter medium in the filter layer 7 comprises quartz sand and river sand, and the quartz sand or the river sand can intercept sludge flocs and reduce the water content of the sludge.
Further, sewage treatment pond 1 with 2 tops in sludge sedimentation pond all are equipped with an access hole 9, conveniently overhaul and the later maintenance sewage treatment pond 1 and sludge sedimentation pond 2.
The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
