Neutralization pond

Technical Field

The invention relates to the technical field of wastewater treatment, in particular to a neutralization pond.

Background

Along with the shortage of water resources and the improvement of environmental protection requirements in China, the water resources and environmental problems faced by thermal power plants are increasingly prominent, and the chemical water plants of the thermal power plants are used as water supply guarantee departments for various production water of power plants, so that more acidic waste liquid can be generated in the whole water production process, and if the acidic waste liquid is directly discharged, the environmental pollution is caused, and the advocated sustainable development in China is also not met.

Therefore, the waste liquid is generally collected and treated in a centralized way by a chemical water neutralization tank. Firstly, adding an alkaline medicament before wastewater enters a neutralization tank by a medicament adding neutralization method, so that acidic wastewater and the medicament are mixed in the tank and then are subjected to neutralization reaction; and secondly, adding a filter material with neutralization performance into the pool by a filtering method, so that the acidic wastewater can be neutralized when passing through the filter material to reach the standard of environmental protection discharge (pH value of 6-9), and then uniformly discharging.

Aiming at a chemical dosing neutralization method, a large amount of sludge can be deposited at the bottom of a neutralization pond in the treatment process, and an anticorrosive coating is arranged on the inner wall of the neutralization pond, so that the mechanical cleaning such as an excavator is prevented from damaging the mechanical cleaning, the manual cleaning is adopted at present, and the time and the labor are consumed. The patent that a publication number is CN208345832U now retrieves discloses a neutralization pond, neutralization pond body bottom is provided with the bottom plate that is used for empting mud, the bottom plate rotates with the bottom of neutralization pond body to be connected, the bottom plate is kept away from the rotation of bottom plate and neutralization pond bottom and is connected one side and be equipped with first connecting rope, first connecting rope is connected with first motor, neutralization pond body bottom is provided with the elevator bucket that is used for the mud that the cell-phone bottom plate emptys, be equipped with the second on the elevator bucket and connect the rope, the second is connected the rope and is connected with the second motor.

The bottom plate arranged at the bottom of the neutralization pond is pulled to be in an inclined state by the first connecting rope, sludge on the surface of the bottom plate slides into the lifting bucket, and the lifting bucket rises to discharge the sludge from the lifting bucket so as to finish desilting operation; however, before dredging, the water in the tank must be completely drained, and then the subsequent operation is performed, so that the cleaning efficiency is low, and the scheme is to be improved.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a neutralization pond which has the advantages of continuous dredging and high-efficiency dredging.

The above object of the present invention is achieved by the following technical solutions:

a neutralization pond comprising: the bottom platform and locate the cell body at bottom platform top, cell body week side level is equipped with oral siphon and outlet pipe, outlet pipe week edge with the cell body diapire is tangent, outlet pipe goes out the water pot head and is equipped with the hose, cell body open end swing joint has the raceway, the hose with be connected with the row silt device between the raceway.
