Description

A petrochemical wastewater treatment sedimentation tank

technical field

The utility model relates to the technical field of sedimentation tank structures, in particular to a sedimentation tank for petrochemical wastewater treatment.

Background technique

In the process of processing and production in the petrochemical field, a large amount of industrial wastewater will be generated, and these wastewater cannot be discharged at will. It must be treated by a strict sewage treatment process and can only be discharged after reaching the specified standard. The common aspects of wastewater treatment are filtration. , precipitation and acid-base neutralization, etc., an important facility in the precipitation process is the sedimentation tank, which is simply a large pond, which reduces the flow rate of the wastewater, so that the insoluble or insoluble in the wastewater is precipitated. When necessary, some specific Additives and catalysts promote precipitation.

Most of the existing sedimentation tanks are large rectangular tanks, which are equipped with a stirring device to mix the additives and the wastewater, so that the insoluble and insoluble substances in the wastewater are precipitated and then discharged. Large and additional stirring devices cause increased costs and have defects.

Utility model content

(1) Technical problems solved

(2) Technical solutions

In order to achieve the above purpose, the present utility model provides the following technical solutions: a petrochemical wastewater treatment sedimentation tank, comprising a sedimentation tank body, the sedimentation tank body is spiral, the sedimentation tank body is provided with a water inlet channel, the The inner wall of the sedimentation tank body is provided with a sloping plate at a position close to the bottom, a connecting pipe is arranged at the wave valley position of the sloping plate, a valve is arranged on the connecting pipe, and the bottom end of the connecting pipe is communicated with the sludge discharge pipe, The sedimentation tank body is provided with a water outlet pipe, and the water outlet pipe bends upwards and then downwards, bypasses the sedimentation tank main body and extends to the outside of the sedimentation tank main body.

Preferably, the water outlet of the water inlet channel is arranged on the periphery of the sedimentation tank body, and the water inlet of the water outlet pipe is arranged at the center of the spiral sedimentation tank body.

Preferably, the water inlet channel is adapted to the diameter of the water outlet pipe, and the height of the water inlet channel is the same as that of the water inlet of the water outlet pipe.

Preferably, the water inlet of the water outlet pipe is higher than the water outlet.

(3) Beneficial effects

The utility model provides a petrochemical wastewater treatment sedimentation tank, which has the following beneficial effects:

The utility model is provided with a sedimentation tank body, a water inlet channel, an inclined plate, a sludge discharge pipe and a water outlet pipe. The sedimentation tank body is arranged in a spiral shape, and the structure is more compact. The area is smaller; the spiral shape is longer than the rectangular flow channel, the sedimentation distance is increased, and the sedimentation effect is better. The wastewater passes through the spiral sedimentation tank body, and the wastewater flows and rotates to achieve the effect of mixing and stirring. It achieves the effect of reducing the floor space, enhancing the sedimentation effect and reducing the cost, and solves the problem that most of the existing sedimentation tanks are large rectangular tanks, which usually occupy a large area and increase the cost caused by additional stirring devices.
