Treatment device for purifying beneficiation sewage through efficient neutral flocculant

Abstract

The invention discloses a treatment device for purifying beneficiation sewage through an efficient neutral flocculant. The treatment device comprises a stirring tank and a precipitation tank which are mutually communicated; the stirring tank is divided into a primary stirring tank and a secondary stirring tank; the precipitation tank is divided into a primary precipitation tank and a secondary precipitation tank; the primary stirring tank, the primary precipitation tank, the secondary stirring tank and the secondary precipitation tank are sequentially communicated; a sewage inlet pipe is communicated with the primary stirring tank through a water feeding tank, and a chemical feeder is arranged above the water feeding tank; a purified water outlet is arranged in the secondary precipitation tank, and a sewage discharging device provided with a blockage clearing device is arranged at the bottom of the secondary precipitation tank; the secondary stirring tank is separated from the secondary precipitation tank through a circular truncated cone, a cylinder and a conical cylinder; the space defined by the inner wall of the circular truncated cone and the inner wall of the lower part of the conical cylinder is the secondary stirring tank, and the space defined by the inner wall of the cylinder, the outer wall of the circular truncated cone and the upper part of the conical cylinder is the secondary precipitation tank. The structure is more compact, the treatment quality and efficiency are higher, and the reliability is higher.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and relates to a sewage treatment device in the mineral processing industry, in particular to a treatment device for purifying mineral processing sewage with a high-efficiency neutral flocculant. Background technique [0002] There are many kinds of sewage treatment processes for mineral processing, among which the use of high-efficiency neutral flocculants to purify mineral processing sewage is one of the emerging methods for the purification of mineral processing sewage in recent years. Flocculant, high-efficiency neutral flocculant is a kind of wastewater purification treatment agent that has been popularized and used in recent years. Its advantages are clean and environmentally friendly, no secondary pollution, fast and efficient, and can complete the purification process in a small space. [0003] In order to make full use of the purification effect of high-efficiency neutral flocc...

AI Technical Summary

Problems solved by technology

[0006] A. Since the process is carried out in sequence according to the primary stirring tank, secondary stirring tank, primary sedimentation tank, and secondary sedimentation tank, although it can also be used, it does not fully meet the requirements of the ideal flocculation process, and the process is not reasonable enough. The growth environment of flocs is not good enough, the individuals after flocculation growth are relatively small, and the small flocs are easy to suspend in the water, resulting in insufficient separation of water body and flocs, and the treatment quality is not high enough

[0007] B. Because the flocs are deposited on the bottom of the static tank, the bottom of the equipment is funnel-shaped, and the flocs are only discharged intermittently through the pipe, which is easy to cause part of the flocs in the pipe to be discharged and partially retained, and finally block the pipe until the flocs unable to discharge

Equipment reliability is not high enough

[0008] C. Since the four main devices of the primary stirring tank, the secondary stirring tank, the primary sedimentation tank and the secondary sedimentation tank are all simple boxes, the structural design is not compact and optimized, and the processing quality and efficiency are not high enough.
