JPS58214393A - Setting tank for adjusting flow amount of filthy water - Google Patents

Abstract

PURPOSE:To effectively eliminate BOD and COD components in filthy water, by providing a sedimenting chamber, a screen and a shower in the setting tank for adjusting a flow amount, and making the wall at the periphery of the tank, a mid dashboard, etc. rugged. CONSTITUTION:Concrete setting tanks 1, 2 are connected to each other by a coupling pipe 3 to constitute the tank 17 for adjusting a flow amount, a sedimenting chamber 8, a screen 9, a shower 11, etc. are provided in said tank 17, and ruggedness 25 is applied to the surfaces of the surrounding wall, mid dashboard, etc. of the tank 17 by sandy coral and oystershells. Hence, aerobes increase in the ruggedness 25 so that pollutants such as BOD and COD components in filthy water can be effectively eliminated.

Description

[Detailed Description of the Invention] This invention provides a sedimentation chamber for settling sand in wastewater in a flow rate adjustment set tank, a screen for removing solid matter from the wastewater, and a screen for discharging solid matter adhering to the screen. .

Add irregularities (coral sand and oyster shells) to the walls and partitions around the flow rate adjustment tank.

Living organisms (aerobic bacteria) can grow in these irregularities, and 40% of pollutants such as BOD and COD in wastewater can be removed in the flow rate adjustment tank. The sewage in the flow rate adjustment tank enters the sewage chamber in the 81 vessel above the water surface at one point, and enters the sewage storage chamber in the sewage agitation stop plate through the opening under the sewage agitation stop plate. The sewage enters the sewage adjustment room and is sent to the sewage biological treatment tank through the sewage adjustment pipe. Excess sewage is returned to the flow rate adjustment tank via the sub-channel pipe. The flow currently being used! The flow rate adjustment tank mold is assembled on site.

- 1;
The sewage that comes from the water pipe is put into the settling chamber, passed through a screen and collected in the flow rate adjustment tank, and then pumped to the water surface.
The sewage is sent to a container, the sewage is adjusted, and then sent to the sewage biological treatment tank. Since this flow rate adjustment tank is built on-site, it takes a long time. Also, since there is no biological breeding device in the current adjustment tank, the flow rate can only be adjusted by adjusting the flow of water.

My father built it on site, so the expenses were quite high. Since the flow rate regulating tank of this invention is made as a complete set in a factory using concrete sets and installed on site, the time required for construction is reduced to one-thirtieth of that required for on-site construction, and the amount of pollutants is 100%.
It eliminates 40% of D, COD, etc., and costs are low. The sewage that comes in from the water pipe 7 enters the settling chamber R, and the sewage that has caused the sand in the sewage to settle to the bottom of the settling chamber is filtered through a screen 9 to remove solid matter from the sewage. In order to prevent odors emitted from solid matter adhering to the screen, the odors adhering to the screen are washed away with waste water from the water pipe of Nyawa 11. In addition, when the screen becomes clogged with solid matter, the waste water is flushed through the secondary channel at a height of 10 IOcym above the water surface of the settling chamber. The sewage flowing from screen 9.

The solid substances in the wastewater are removed using the following detailed 12 screens.
In addition, if the screen [(adhering substances are washed away with Shower II. The sewage that comes out from screen 12 is
It uses 1lli15jc of fine mesh to remove solids from wastewater. The sewage that falls through the 15 fine mesh baskets falls into the flow rate adjustment tank 17 below. The sewage collected in the flow rate adjustment tank has unevenness 25 (coral sand and oysters) on both sides of the wall of the tank body 1 and the plate of the soil protection 19, and living things (bacteria) breed on these four convex surfaces. From the air pipe 24 above the water surface of the adjustment tank.

The air diffuser at the bottom sends 22vc air, scattering the air into the wastewater in the flow 1 adjustment tank, and rotating the wastewater. Connect the 2nd seventh throat tank 26 with the connecting pipe 3 (heat pipe) VC, I
n! Similar to the first set of tanks, the air diffuser pipe 27 is attached to the bottom of the biofouling tank 26, and the second set of seven throat tanks is connected to the first flow rate adjustment tank 1.
Similar to 7, wastewater is treated biologically. When the waste water rises to a certain level, the pump 28 is activated, and the measuring device 29 above the water level is activated.
The sewage enters the sewage storage chamber 30, rises from the bottom of the sewage agitation stop plate 31, and is sent to the biological treatment tank through the adjustment pipe 32. Excess sewage is returned to the flow rate adjustment tank via the sub-channel 33 pipe. When the sewage in the flow rate adjustment tank reaches a certain level, the pump 28 sends the sewage to the metering chamber, and when the water level drops to a certain level, the pump stops. During this time, the unevenness 25 (sand/god sand + key shell) on the wall around the tank comes out of the water surface, and the organisms attached to the unevenness come into contact with the air, which increases the reproduction of living organisms. Since the solid material rotates the sewage with the air rising from the aeration pipe, the solid material hits the uneven surface of the biofouling and grinds it up, which reduces the amount of sludge. This invention provides a sewage flow adjustment set tank that can eliminate 50% of pollutants BOD and COD in wastewater in the flow adjustment tank.
