Technical Field

The utility model belongs to the environmental protection field relates to the sewage treatment field, concretely relates to sewage treatment solid-liquid separation equipment.

Background

Current sewage treatment divide into chemical treatment and physical treatment two aspects, chemical treatment is through the corresponding impurity of medicament reaction removal sewage, physical treatment is through the filter screen, the grid, centrifugal separation etc. get rid of corresponding impurity, the realization is to the solid-liquid separation of sewage, in order to promote the treatment effect, often need adopt chemical treatment and physical treatment simultaneously, actually carry out chemical treatment in the chemical treatment pond in advance, handle the good sewage pump of chemical treatment in-pool processing and go into physical treatment in the pond and carry out physical treatment, it is in the middle of the actual process, still there is following defect:

1. chemical treatment pond and physical treatment pond adopt continuous water pump water delivery, because the power of water pump can produce certain rocking for the chemical treatment pond in, this can lead to the debris that the bottom was depositd to turn over, again under the suction effect of water pump, be difficult to avoid having some debris and then the water behind the upper strata reaction go into the physical treatment pond together, and these debris often are that the unable separation of physical treatment to lead to final solid-liquid separation effect can receive the influence.

2. The water pump is difficult to guarantee to preferentially suck the water on the uppermost layer in the chemical treatment pool, so that some water which is not fully treated can be pumped into the physical treatment pool, and the final solid-liquid separation effect can be influenced.

3. In the whole treatment process, a water pump needs to be continuously started between the chemical treatment tank and the physical treatment tank for water delivery, so that the energy consumption is high.

Disclosure of Invention

The purpose of the invention is as follows: in order to overcome the defects in the prior art, the solid-liquid separation device for sewage treatment is provided, which can improve the treatment effect and reduce the energy consumption.

The technical scheme is as follows: in order to realize the above object, the utility model provides a sewage treatment solid-liquid separation equipment, including chemical treatment pond and physical treatment pond, chemical treatment pond and physical treatment pond are fixed respectively on the support frame, the chemical treatment pond is located the top in physical treatment pond, the chemical treatment pond internal fixation is provided with fore-and-aft warning pipe, the top of warning pipe is located the pool face below in chemical treatment pond, and the bottom downwardly extending chemical treatment pond is and stretch into to the physical treatment pond in, the internal fixation of physical treatment is provided with fore-and-aft outlet pipe, the top of outlet pipe is located the pool face below in physical treatment pond, and the bottom downwardly extending physical treatment pond is used for going out water, be provided with the inlet tube on the chemical treatment pond, be located in the physical treatment pond and be provided with the filter layer between warning pipe delivery port and the top.

Furthermore, the overflow pipe and the water outlet pipe are respectively arranged at the central positions of the chemical treatment tank and the physical treatment tank.

Furthermore, the bottom of the chemical treatment tank inclines towards the overflow pipe, and the bottom of the physical treatment tank inclines towards the water outlet pipe, so that the settled impurities can be collected, and subsequent pollution discharge is facilitated.

Furthermore, the bottom of the chemical treatment pool and the bottom of the physical treatment pool are respectively provided with a first drain outlet and a second drain outlet.

Furthermore, a reinforcing rib block is arranged between the support frame and the overflow pipe, so that the connection strength of the whole structure of the solid-liquid separation device is improved.

The utility model discloses in the connection through the support frame, design into upper and lower structure with chemical treatment pond and physical treatment pond, and carry the water after the processing in the chemical treatment pond to the physical treatment pond through the warning pipe, because what adopt is the mode of overflow, carry power self power for water, can save the water pump as transport means, can not produce the condition of stirring in the treatment pond, and only the water that surpasss warning pipe and outlet pipe can flow automatically, the water that does not fully handle can not flow, guaranteed the abundant reaction to the interior sewage of treatment pond, the solid-liquid separation effect has been promoted.

Has the advantages that: compared with the prior art, the utility model, possess following advantage:

1. the water which is not fully reacted can not flow out of the reaction tank, and the integral solid-liquid separation effect is improved.

2. The overflow mode is adopted to replace the original conveying mode of the water pump, so that the problem that impurities are easily sucked by the water pump in the prior art is solved, the energy consumption is reduced, and the process cost is reduced.

3. The chemical treatment tank and the physical treatment tank are designed longitudinally, so that the overall occupied space of the separation device is greatly reduced, the site limitation is reduced, and the site cost is reduced.
