Embodiment 1

[0041] Such as figure 1 - Figure 4 As shown, the present embodiment provides a natural stirring mixing device, including a frame and a flocculation fin 4 arranged in the frame;

[0042] Sickle fins 6 are arranged on the floc fins 4 .

[0043] Most of the coagulation tanks in traditional high-density sedimentation tanks are equipped with agitators or mixers for mixing by means of mechanical agitation, which not only requires high equipment, troublesome construction and installation, but also requires frequent maintenance, high maintenance costs, time-consuming and laborious, and increases Reduced production costs and reduced production efficiency. In view of this, the present invention provides a natural agitation high-efficiency mixing device through hydraulic mixing, in which sewage and medicament / coagulant are mixed efficiently and fully. Hydraulic mixing is used instead of mechanical mixing, which reduces mechanical investment and has a very low failure rate. It can not...

Abstract

The invention belongs to the technical field of water treatment and relates to a natural stirring and mixing device and a high-density sedimentation tank. The natural stirring and mixing device provided by the invention comprises a frame and flocculating flow wings arranged inside the frame, wherein the flocculating flow wings are provided with sickle wings. The high-density sedimentation tank provided by the invention comprises a coagulating tank, a flocculation tank and a sedimentation tank which are communicated with each other, wherein the natural stirring and mixing device is arranged atthe bottom of the coagulating tank. The device has the characteristics of simple structure, convenience in operation and installation, low energy consumption, investment saving and good mixing effect,and can effectively relieve the problems of power consumption, large maintenance quantity, inconvenient construction and installation and the like caused by an electric mixer adopted in the prior art.

Description

technical field [0001] The invention belongs to the field of water treatment, and relates to equipment for sewage treatment, in particular to a natural stirring and mixing device and a high-density sedimentation tank. Background technique [0002] Water is a very precious natural resource. With the development of modern industry, the continuous expansion of city scale, the continuous increase of water consumption and waste water, the phenomenon of water shortage is becoming more and more serious. Saving water is a more realistic way to alleviate this problem, and It is an effective way to save water after the sewage is treated at the reclaimed water station and reaches the reclaimed water utilization standard. At present, reclaimed water reuse treatment can be roughly divided into three commonly used technologies, namely coagulation and filtration, biological treatment sedimentation and membrane separation, of which the first two are currently more commonly used technologies...
