In general, when treating sewage or wastewater or purifying water, it undergoes a sedimentation process. In this sedimentation process, sludge is generated in the reactor, the sludge is stacked on the bottom of the reactor, and the stacked sludge is used for filtration, sedimentation, and neutralization. It is treated through the physicochemical method of wastewater treatment technology by chemical treatment.

In addition, the SBR (Sequencing Batch Reactor) method is used in such a sludge treatment system. The SBR method continuously performs the inflow, reaction, precipitation, discharge, and rest processes in one reactor, and the biggest advantage of this method is that one Since the reaction and precipitation proceed in the tank, there is no need for a final settling cell, and it can respond flexibly according to the water quality of the wastewater, and all processes are automatically operated at a certain time and cycle, so it is convenient to manage.

However, despite these advantages, the conventional sludge treatment system is of a batch type, and therefore, since it is necessary to treat the sludge contained in the large-capacity treated water accommodated in the large water tank, the operation and treatment time per cycle takes a long time. However, there is a problem in that a large amount of coagulant, which is a drug to be injected, is also required.

More specifically, the overflow wall 130 is attached and installed on the inner wall of the settling promoting tank 100, and the height of the overflow wall 130 attached and installed is higher than the inflow passage 101 and the outflow passage 102. After the primary sludge coagulation in the coagulation guide body 400 to be described later, the sludge remaining in the treated water discharged through the lower part of the coagulation guide body 400 is secondary to flocculation and at the same time it settles, and the sludge is coagulated. It performs a function of controlling the overflow wall 130 to overflow and outflow as the water level of the removed treated water rises.

In particular, the block 131 for maintaining the flow rate protrudes from the upper side of the overflow wall 130 at regular intervals, so that the treated water that overflows the sludge is agglomerated and removed flows at a constant speed, that is, it functions to maintain a constant flow rate as much as possible. make it possible

The mixing efficiency is further improved by forming turbulence while colliding.

In addition, a plurality of spinnet plate parts 500 coupled to the rotating shaft 220 are installed at predetermined intervals, that is, about 2 to 8 spinnet plate parts 500 about the rotating shaft 220 are radially installed. provided to be combined.

In particular, the number of pitching nets 520 is different between the adjacent spinnet plate parts 500 according to the size of the pitching nets 520 installed on the rotating plate 510, or the pitching nets 520 installed on the rotating plate 510. By forming different shapes of , it maximizes the formation of turbulence, further improving the mixing efficiency.

As an example, with reference mainly to FIG. 3 , the pitcher net 520 installed on the rotating plate 510 constituting the spinnet plate part 500a of one of the two adjacent spinnet plate parts 500a and the spinnet plate part 500b. ) is reduced in size, and four are installed, and three pitchers nets 520 installed on the rotating plate 510 constituting the other spinnet plate part 500b are enlarged in size.

Through this, the treated water pitched through the four pitching nets 520 installed on the rotating plate 510 constituting the spinnet plate part 500a on one side is finely classified and pitched, but the next spinnet plate part ( When the flow is changed when passing through the three permeable networks 520 installed on the rotating plate 510 constituting 500b), more turbulence is formed, and through repetition of this process, the mixing efficiency is further improved.

In addition, in the sludge collection device for accelerating sludge sedimentation of the present invention, the flocs formed by the flocculation reaction in a small reaction space that induces a reaction between the treated water and the flocculating agent are induced to settle as uniformly as possible on the bottom surface. to provide.

It is formed to be smaller than the diameter of the through hole 411 so that the flocs that are settling are collected and led to settling.

In addition, the upper side is connected to the lower end of the coagulation guide body 400 so that the flocs formed by the agglomeration of the sludge in the interior of the coagulation guide body 400 settle toward the bottom, and the upper and lower sides are opened. However, the downward guide tool 420 made of a trapezoidal shape having a larger inner diameter of the lower layer than the inner diameter of the upper layer is provided.

To this end, the sludge collection device for facilitating sludge sedimentation of the present invention is fixedly connected to the rotating shaft and includes a bottom scraper unit 600 that prevents sludge from being deposited on the bottom of the sedimentation accelerator 100 .

As such, the detailed configuration of the bottom side scraper part 600 that provides this function is a support plate 610 through which the rotation shaft 220 passes, the side surface is fixed to the rotation shaft 220, and the lower surface is fixed to the support plate 610, A plurality of fixing plates 620 for fixing the support plate 610 to the rotation shaft 220, one side is bolted to the upper surface of the support plate 610, and the other side is connected to the rotation shaft 220 with a wire 631 and fixed to the rotation table ( 630) and the upper side is connected to the rotating table 630, and the lower side consists of a contact hole 640 that is in contact with the bottom of the settling promoting tank (100).

The other end is branched and provided.

To explain this in more detail, excess sludge may be discharged excessively or, conversely, a problem may occur when discharging a small amount.

First, when excess sludge is discharged, the concentration of returned sludge transferred to another treatment process is low, which affects the water treatment process. As the sludge decay phenomenon or denitrification reaction is caused, the sedimented sludge rises again on the surface of the settling basin and acts as a factor deteriorating the quality of the treated water.

Accordingly, the sludge interface sensor 800 applies an ultrasonic sensor to measure the height of the sludge layer in the settling tank in real time to detect the sludge interface state inside the settling tank, that is, by irradiating ultrasonic waves into the water, the sludge interface is reflected back The state of the interface can be known by the time difference, and the surplus sludge is automatically discharged according to the sludge concentration and the state of the interface layer by interlocking with the amount of surplus sludge through the control panel. If there is no difference, it is possible to automatically inject the coagulant in conjunction with the chemical injection unit 300, thereby performing a control function so that the surplus sludge discharge time and the amount of returned sludge can be adjusted.
