Background

The sewage treatment device sludge concentration tank is connected to the sludge lifting tank by using a buried pipeline, and in normal operation, the supernatant liquid after the biochemical system sludge enters the sludge concentration tank for concentration enters a device sewage well through overflow, and the concentrated sludge flows into the sludge lifting tank through gravity. In the operation process, the condition that the sludge treatment system is overhauled and can not process sludge sometimes appears, in order to prevent that the overflow from taking place for the sludge lifting pond, the sludge concentration pond can be closed to the sludge lifting pond valve, when the sludge treatment system overhauls and resumes normal operation, the condition that the sludge concentration pond can appear the jam to the sludge lifting pond pipeline sometimes, causes the unable mud of device to arrange. According to the prior art, the device performs pipeline dredging by the following method:

under normal conditions, after a pipeline is blocked, an outlet valve of a standby concentration tank is opened, and the outlet valve of the standby concentration tank and an inlet valve of a sludge lifting tank are kept to be normally opened, wherein the liquid level of the sludge concentration tank and the sludge lifting tank is higher, the standby concentration tank is at a low liquid level, the liquid level difference is about 3m, and the sludge lifting tank and the sludge in the sludge concentration tank can slowly flow into the standby concentration tank under the driving of the pressure difference, so that pipeline dredging is realized;

if the method can not realize dredging, the liquid level of the sludge lifting tank is reduced to about 1m by utilizing a sludge feeding pump on the basis of the steps, the liquid level difference between the concentration tank and the sludge lifting tank is increased to about 4m, and the sludge flows from the in-use sludge concentration tank to the standby sludge concentration tank and the sludge lifting tank, so that pipeline dredging is realized; if the method still cannot realize dredging of the concentration tank, the temporary submersible pump is used for further pumping down the standby sludge concentration tank, the liquid level difference (5 m) between the two concentration tanks is further increased, and pipeline dredging is realized by means of larger gravity.

In general, because the outlet sludge pipeline of the sludge concentration tank is frequently blocked, pipeline dredging is carried out on site by means of gravity flow of sludge, and the following defects occur in the actual use process:

1. the gravity flow pressure is smaller, the dredging time is longer each time, the pipeline is not thoroughly dredged, and the possibility of later blockage is increased;

2. the method III has large workload when being used for dredging, special temporary electricity utilization operation is needed, and a large amount of manpower and material resources are consumed;

3. because the dredging time is longer, the system can not normally discharge mud in the dredging process, so that the concentration of the system mud is increased, and the system fluctuation is easy to cause.
