Embodiment Construction

[0031] The application and implementation method of the device of the present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited thereto.

[0032] Such as figure 1As shown, in the normal operation mode, after the raw water is coagulated by adding flocculants and coagulants, it enters the water distribution tank 2 from the water inlet 1, and enters the sedimentation area through the water distribution flower wall 3, and the flocs formed by some colloids and particles in the water are deposited. The area directly sinks into the mud collecting bucket 4, or slides down to the mud collecting bucket 4 at the bottom of the sedimentation area after settling in the inclined pipe 5. The purified water flows upward through the inclined pipe 5, and after being collected by the sump 7, the water outlet 10 enters the next unit. At this time, the water outlet valve 8 is fully opened, and th...

Abstract

The invention discloses an inclined tube sedimentation tank capable of being cleaned on line. A cathode electrode plate and an anode electrode plate are respectively arranged on two sides of the inclined tube surface of the inclined tube sedimentation tank. When floc is deposited on the surface or the top of the inclined tube, the cathode electrode plate and the anode electrode plate are electrified, oxygen and hydrogen are generated by electrolyzing water, and microbubbles are formed on the surface of the inclined tube; then the microbubbles adhere to floc deposited in the inclined tube, so that the deposited floc floats on the water surface and enters the top water collecting tank to be discharged out of the system. According to the invention, the microbubbles are formed on the surface of the inclined tube through electrolyzed water or electrolyte in the electrolyzed water, and the microbubbles adhere to floc deposited in the inclined tube, so that the deposited floc floats on the water surface and enters the top water collecting tank to be discharged out of the system. The device is suitable for other solid-liquid flow directions such as a same-direction flow inclined pipe and a lateral flow inclined pipe; and the device is suitable for other sludge discharge forms such as mechanical sludge discharge and perforated pipe sludge discharge. The inclined tube sedimentation tank is suitable for pretreatment and advanced treatment of purified water, sewage, reclaimed water and seawater in the fields of municipal administration, industry, agriculture and the like.

Description

technical field [0001] The invention relates to the technical field of water treatment equipment, in particular to an inclined tube sedimentation tank which realizes on-line cleaning by electrolytically generating microbubbles on the surface of the inclined tube in situ. Background technique [0002] The sedimentation tank is an important facility for solid-liquid separation in the process of water purification. In order to ensure the effective removal of suspended solids, flocs and colloids in the water purification process, the inclined tube sedimentation tank and its improved tank type have been widely used. [0003] The inclined tube sedimentation tank is based on the principle of shallow pool sedimentation, and the sedimentation distance is shortened by increasing the sedimentation area; the floc growth is promoted by re-coagulation in the inclined tube; laminar flow conditions are created by rectification, so it has high treatment efficiency and large surface load. adv...
