Abstract

Provided is a water-level-variable terminal catchment inclined tube or inclined plate sedimentation tank. The invention relates to a sedimentation tank to solve the problem that the water in conventional inclined tube / inclined plate sedimentation tanks can not adjust with the change of influent load, and the gathered water yields in effluent weirs are large. A plurality of effluent weirs are disposed on the top of rear section of a tank body. A plurality of stand columns are disposed on the terminal section of the tank body water inlet terminal and any longitudinal sides of the tank body. A fixed flashboard and a movable flashboard which are mutually parallel are arranged between each two stand columns. The fixed flashboards are located on the outside of the tank body. The movable flashboards are located inside of the tank body. The lower terminal faces of the fixed flashboards and the movable flashboards are all provided with a plurality of water inlet holes. The above of each movable flashboard is provided with a hoist. Start and stop levers on the hoists are connected with the movable flashboards. Both sides of each effluent weir are respectively provided a lifting board. The lower terminal of each lifting board is uniformly provided with a plurality of lifting rods along the length of the lifting board. The lower terminal of each lifting rod is provided with a regulator. The sedimentation tank is used for removing the water turbidness.

Description

technical field [0001] The invention relates to a settling tank, in particular to a settling tank with inclined tubes at the end of variable water level collection. Background technique [0002] The water purification process with traditional coagulation-sedimentation-filtration-disinfection as the core is a treatment system that mainly removes turbidity in water and takes into account other conventional indicators. The types of impurities removed in water are mainly suspended solids and colloids . At present, many large cities in Northeast China are gradually adopting lakes and reservoirs as source water. According to the preliminary test analysis, this type of water has the characteristics of low turbidity, high chroma, and low water temperature, and belongs to the typical lake and reservoir type source water in cold regions. This type of water contains a large amount of humus substances, and there will still be a large amount of residue after conventional processing. Ac...
