Embodiment 1

[0024] The agitator 4 adopts a fully submerged vertical installation, the rotating speed is 960r / min, the outer diameter of the paddle is 400mm, and the angle is 15°; the diameter of the spoiler 5 is twice the outer diameter of the paddle of the agitator 4. The mesh on the barrel 5 is a round hole with an opening rate of 70%; the discharge port of the L-shaped feed pipe 8 is placed 15 mm below the blade of the agitator 4 . The source water mixed with polyaluminum chloride enters the high-speed stirring mixing reactor, driven by the driving device, the high-speed stirring equipment stirs the water body, the reaction time is 10s, and then enters the original flocculation tank, sedimentation tank, sand filter in sequence pool.

Embodiment 2

[0026] The agitator 4 adopts a fully submerged vertical installation, the rotating speed is 800r / min, the outer diameter of the paddle is 360mm, and the angle is 20°; the diameter of the spoiler 5 is 2.5 times the outer diameter of the paddle of the agitator 4. The mesh on the barrel 5 is a round hole with an opening ratio of 50%; the discharge port of the L-shaped feed pipe 8 is placed 10 mm below the blade of the agitator 4 . The source water mixed with polyaluminum chloride enters the high-speed stirring mixing reactor. Driven by the driving device, the high-speed stirring equipment stirs the water body. The reaction time is 8s, and then enters the original flocculation tank, sedimentation tank, and sand filter in sequence. pool.

Embodiment 3

[0028] The agitator 4 adopts a fully submerged vertical installation, the rotating speed is 1200r / min, the outer diameter of the paddle is 200mm, and the angle is 5°; the diameter of the spoiler 5 is 3 times the outer diameter of the paddle of the agitator 4. The mesh on the barrel 5 is a round hole with an opening rate of 80%; the discharge port of the L-shaped feed pipe 8 is placed 30 mm below the blade of the agitator 4 . The source water mixed with polyaluminum chloride enters the high-speed stirring mixing reactor, driven by the driving device, the high-speed stirring equipment stirs the water body, the reaction time is 5s, and then enters the original flocculation tank, sedimentation tank, sand filter in sequence pool.

[0029] The high-speed coagulation reactor for water treatment optimizes the mixing from two aspects: increasing the diffusion speed and forming micro-vortex diffusion.

Abstract

The invention particularly relates to a high-speed coagulation reactor for feed water treatment. The high-speed coagulation reactor for feed water treatment comprises a reactor tank body, a water inlet pipe and a water outlet pipe. An L-shaped feeding pipe is arranged on the upper portion of the reactor tank body. Meanwhile, a stirrer and a flow disturbing cylinder are further arranged inside the reactor tank body. The stirrer is arranged in the center of the reactor tank body and connected to a motor through a speed reducer. The flow disturbing cylinder is fixed to the top end of the reactor tank body and located between the stirrer and the reactor tank body. The water inlet pipe and the water outlet pipe are embedded into the outer walls of the left side and the right side of the reactor tank body correspondingly. The high-speed coagulation reactor for feed water treatment can improve the mixing rate, shorten the mixing time and improve the removal rate of organic matter through coagulating sedimentation, so that the follow-up flocculation effect, the sedimentation effect and the filtering effect are further improved, and the quality of water discharged from a filter chamber in the following period is remarkably improved; and meanwhile, the dosage of a coagulant can be further reduced, the volume of a mixing pool is reduced, and the operating cost and the engineering construction investment are reduced.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a high-speed coagulation reactor for water treatment. Background technique [0002] At present, most of the effluent turbidity of sedimentation tanks of water purification plants using conventional treatment processes in my country is 1 to 3 NTU, and the turbidity of effluent water from filters generally does not exceed 1 NTU; while the turbidity of effluent water from sedimentation tanks of foreign advanced water purification plants using similar processes The turbidity of the filter water is not higher than 1NTU, and the turbidity of the filter water is not higher than 0.1NTU. It can reach the standard of direct drinking water without advanced treatment. However, after the domestic conventional treatment process, it is necessary to increase the advanced treatment of membrane filtration to make the turbidity of the water supply reach a level not higher than 0.1NTU. In or...
