Description

Automatic washing unit of sedimentation tank play mill weir
Technical Field
The utility model belongs to the technical field of the technique of the play weir clearance of circular sedimentation tank and specifically relates to an automatic washing unit of sedimentation tank play weir is related to.
Background
The circular sedimentation tank is a common structure for treating sewage. The mud-water mixed liquid enters the tank body from a water inlet pipe at the center of the bottom of the tank, and slowly flows to the periphery of the tank along the radius direction in a radial direction after diversion and water distribution. Along with the reduction of the speed of the radiant flow, suspended matters are separated in the flow and settle at the bottom of the water, and enter a sludge hopper along the gradient of the bottom of the tank, and clarified water overflows from the periphery of the tank to a water outlet weir at the periphery of the tank to discharge water.
The sedimentation tank mostly adopts a rotary mud scraping bridge to collect the sludge. The rotary bridge frame of the rotary mud scraping bridge takes the center as the circle center, the end part of the rotary bridge frame runs circumferentially by taking the pool platform of the sedimentation pool as a track under the action of a driving device, the mud scraping plate of the rotary mud scraping bridge scrapes and collects the mud at the bottom of the sedimentation pool during running, the mud is scraped to a mud bucket at the center of the pool and is discharged by gravity or a mud pump.
The sedimentation tank is characterized in that the water outlet weir is annular, the weir body is long, water flows out from two sides, the periphery of the water outlet weir is not shielded, the water outlet weir is seriously exposed to the sun, algae grow in large quantities under the condition that nutrient substances in water are rich in nitrogen and phosphorus, and the periphery of the tank wall grows vigorously in summer and winter.
Algae have the following effects on sewage treatment: 1. algae can fall off after growing to a certain degree, enter a subsequent unit of sewage treatment, increase the burden of a filter tank, seriously influence the sewage filtering effect and cause the standard exceeding of part effluent indexes; 2. when the algae is excessive, a large amount of fallen algae can be intercepted by the ultraviolet disinfection device, so that the disinfection effect is poor, the front backflow grid of the ultraviolet disinfection device needs to be cleaned every day, meanwhile, the ultraviolet disinfection device is cleaned once in half a month, the workload is greatly increased, if the cleaning is not timely, the ultraviolet disinfection effect is influenced, and simultaneously, the SS index is influenced, the fallen algae still contains organic components, the COD is greatly influenced after the fallen algae is monitored and taken on line, and the condition is filtered completely, so that the energy consumption is increased; 3. seriously affecting the beauty of the sedimentation tank.
The conventional method for removing algae is to manually scrape off algae around the effluent weir after stopping the operation of the sedimentation tank. Not only causing the stagnation of sewage treatment and reducing the treatment efficiency; the algae that strikes off also can enter into the outside clear water of play weir or the inside sewage of play weir, still need carry out artifical salvage, greatly increased the operation degree of difficulty.
