Problems solved by technology

There are some disadvantages in these two structures, mainly when the filler and filter are clogged, it is inconvenient to clean, and it can only be cleaned when the system is out of service.
Secondly, it does not consider the filling of flocculant or coagulant and solve the problem of rapid coagulation
Thirdly, the purification efficiency is not high, and it is difficult for the treated water to meet the discharge standard at one time or to be directly reused

Embodiment 1

[0037] See Figure 1 to Figure 5 This embodiment includes an inner cylinder 18, a filter cylinder 12 and an outer cylinder 11 coaxially nested from inside to outside. The top of the filter cylinder 12 and the outer cylinder 11 is provided with a top plate 17, a cyclone flocculation tank 15 is installed above the top plate 17, and the upper end of the inner cylinder 18 extends into the cyclonic flocculation tank 15 and is connected to the cyclonic flocculation tank 15 The tank body is concentric, the part of the inner cylinder 18 extending into the cyclone flocculation tank 15, and the connection with the top plate is provided with a sewage inlet tangential to the outer diameter of the inner cylinder; below the filter cylinder 12, the bottom of the inner cylinder 18 is connected to The bottom of the outer cylinder 11 is provided with an inclined tube sedimentation packing layer 5, the inclined tube sedimentation packing layer 5 is installed on the inclined tube packing bracket 4...

Embodiment 2

[0041] See Image 6 , Figure 7 The structure of this embodiment is basically the same as that of the first embodiment. The difference lies in the arrangement and structure of the filter layer.

[0042] From Image 6 , Figure 7 It can be seen that this embodiment includes an inner cylinder 18 and an outer cylinder 11 that are coaxially nested from the inside to the outside; a top plate 17 is provided on the top of the outer cylinder 11, and a cyclone flocculation tank 15 is installed above the top plate 17, and the inner The upper end of the cylinder 18 extends into the cyclonic flocculation tank 15 and is concentric with the cyclonic flocculation tank 15; the upper part of the cyclonic flocculation tank 15 is provided with a sewage inlet 16 and a flocculant filling port, and the inner cylinder 18 extends into In the cyclone flocculation tank 15, there is a sewage inlet tangential to the outer diameter of the inner cylinder at the connection with the top plate; between the bottom...

Embodiment 3

[0046] See Picture 10 In this embodiment, on the basis of the second embodiment, the circular filter layer is eliminated as needed. Above the inclined pipe sedimentation packing layer 5 is the clean water outlet chamber. The clean water outlet chamber is divided into several independent clean water outlets by partitions. In the water compartment, the position of the outer cylinder corresponding to each water purification compartment is respectively provided with an overhaul manhole and a common interface for the purification water outlet and the reverse cleaning water inlet.

Abstract

The invention discloses flocculation, swirling, precipitation and filtration integrated sewage treatment equipment. The equipment mainly comprises an inner cylinder and an outer cylinder, wherein the inner cylinder is coaxially embedded in the outer cylinder; the top of the outer cylinder is provided with a top plate, a swirling-type flocculation tank is installed on the top plate, and the upper end of the inner cylinder extends into the swirling-type flocculation tank and is concentric with the tank body; the junction between the part, extending into the swirling-type flocculation tank, of the inner cylinder and the top is provided with a sewage inlet tangential to the outer diameter of the inner cylinder; an inclined pipe precipitation packing layer is arranged between the bottom of the inner cylinder and the bottom of the outer cylinder and installed on an inclined pipe packing bracket, and the lower end of the inner cylinder slightly protrudes out of the inclined pipe packing bracket; a sludge collection hopper is arranged below the outer cylinder, the bottom of the sludge collection hopper is provided with a sludge outlet and a valve, and a steel bracket is arranged below the sludge collection hopper. An annular filtering layer is arranged between the portion, between the inclined pipe precipitation packing layer and the top plate, of the outer cylinder. The equipment integrates various processes of flocculation, swirling, precipitation and filtration and is simple in structure, convenient to maintain and high in purification efficiency.

Description

Technical field [0001] The invention belongs to the technical field of sewage treatment, and specifically relates to a sewage treatment equipment that integrates flocculation, swirling, precipitation, filtration and other processes in an integrated structure. Background technique [0002] In the production process of mining, coal washing, pharmaceutical and other industrial and mining enterprises, a large amount of sewage will be generated. These sewage contains a large amount of particulate matter, so it is necessary to use a treatment device to purify the sewage before discharging or to reuse the purified water. [0003] For occasions with high fixed particles, cyclones (desander) are usually used for pretreatment to remove most of the coarse particles. The method of flocculation + coagulation is used to agglomerate fine particles into large particles, and then an inclined tube (plate) is used for precipitation. The flocculation tank, coagulation tank, and sedimentation tank of...
