Abstract
The invention relates to a horizontal flow sedimentation tank, which comprises a tank body, wherein a vertical sludge inlet pipe is arranged at the left side of the tank body, which is close to the inner wall of the tank body, a sludge collecting hopper is arranged at the bottom of the right side of the tank body, the bottom of the tank body is of a downward inclined slope structure, the slope is downward inclined from one side of the sludge inlet pipe to the sludge collecting hopper, a sludge discharge port is arranged at one side of the sludge collecting hopper, and an overflow port is arranged on the side wall of the right side of the top of the tank body; the plurality of inclined plates are obliquely and upwards arranged to one side of the overflow port from one side of the sludge inlet pipe, the bottom of the sludge inlet pipe is positioned below the lowermost inclined plate, and the overflow port is positioned above the uppermost inclined plate.
Description
Technical Field
The invention relates to a sedimentation tank for sewage treatment, in particular to a horizontal flow type sedimentation tank.
Background
The sedimentation tank is a common structure for separating suspended solids and can be divided into a horizontal flow type, a vertical flow type and a radial flow type according to different water flow directions in the tank. The horizontal flow sedimentation tank is generally rectangular and consists of a water inlet, a water outlet and a sludge hopper, and clear liquid is collected by adopting a method of downward feeding and upward discharging. The horizontal flow sedimentation tank has simple structure but larger occupied area; the separation effect is limited when the wastewater with more mud content and high ss content, such as alcohol first-grade anaerobic wastewater, is encountered.
Disclosure of Invention
The invention aims to provide a horizontal flow type sedimentation tank with multi-stage overflow and full sedimentation.
The technical scheme adopted by the invention is as follows:
a horizontal flow sedimentation tank comprises a tank body, wherein a vertical sludge inlet pipe is arranged on the left side of the tank body close to the inner wall of the tank body, a sludge collecting hopper is arranged at the bottom of the right side of the tank body, the bottom of the tank body is of a downward inclined slope structure, the slope is downward inclined from one side of the sludge inlet pipe to the sludge collecting hopper, a sludge discharge port is arranged on one side of the sludge collecting hopper, an overflow port is arranged on the side wall of the right side of the top of the tank body, a plurality of parallel inclined plates which are arranged at equal intervals are arranged in the tank body, the front end and the rear end of each inclined plate are respectively; the plurality of inclined plates are obliquely and upwards arranged to one side of the overflow port from one side of the sludge inlet pipe, the bottom of the sludge inlet pipe is positioned below the lowermost inclined plate, and the overflow port is positioned above the uppermost inclined plate.
After the technical scheme is adopted, the invention has the beneficial effects that:
the inclined plates form a 15-30 degree angle with the horizontal plane, the bottom of the sedimentation tank forms a-15-45 degree angle with the horizontal plane, the mud water in the mud inlet pipe begins to sediment after entering the tank, the mud water is blocked by the inclined plates after reaching a certain height and further sediments, and the mud water overflows each grade of inclined plates in sequence due to the inclined plates which are arranged obliquely upwards, so that the sedimentation of the mud is promoted, and the sedimentation effect is good; the design is simple and easy to implement, and is more beneficial to complete sludge precipitation. The ss reduction of the wastewater after passing through the horizontal flow sedimentation tank is more obvious through detection.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
The following detailed description of embodiments of the invention is provided in conjunction with the accompanying drawings:
as shown in the figure, the advection type sedimentation tank comprises a tank body 1, wherein a vertical sludge inlet pipe 2 is arranged on the left side of the tank body 1 close to the inner wall of the tank body, a sludge collecting hopper 3 is arranged at the bottom of the right side of the tank body, the bottom of the tank body is of a downward-inclined slope 4 structure, a slope 4 is downward inclined from one side of the sludge inlet pipe 2 to the sludge collecting hopper 3, a sludge discharge port 5 is arranged on one side of the sludge collecting hopper 3, an overflow port 6 is arranged on the side wall of the right side of the top of the tank body 1, a plurality of parallel inclined plates 7 which are arranged at equal intervals are arranged in the tank body 1, the front end and the rear end of each inclined plate; the inclined plates are obliquely and upwards arranged to one side of the overflow port 6 from one side of the sludge inlet pipe 2, the bottom of the sludge inlet pipe 2 is positioned below the lowermost inclined plate, and the overflow port 6 is positioned above the uppermost inclined plate.
