Description

Separating device for water treatment Technical Field The utility model relates to the technical field of water treatment, in particular to a separation device for water treatment. Background The activated sludge process is the most commonly used treatment process for treating organic wastewater, and is a process of introducing aerobic microorganism strains into an aerobic bioreactor (an aeration tank) and introducing air to generate aerobic metabolism so as to decompose organic matters into carbon dioxide and water. In order to obtain cleaner water, the sewage, sludge and air after the aerobic reaction are effectively separated. Conventionally, an independent secondary sedimentation tank is arranged outside an aerobic bioreactor to separate sludge and sewage, and air separation is performed in the bioreactor in advance, so that although air separation and sludge-water separation can be achieved without mutual interference, equipment such as a sludge scraper and a sludge reflux pump are also required to be arranged, investment and operation cost are increased, separation efficiency is low (surface load is generally not more than 1.0m < 2 >. H), and occupied area is large. In order to eliminate the defects of the secondary sedimentation tank, a three-phase separator is arranged in the bioreactor to replace the secondary sedimentation tank, and simultaneously, three-phase separation of sewage, sludge and air is realized, but because the interference of air on the sludge-water separation is not well solved, the sludge-water separation effect is poor, the sludge is attached to the air and floats upwards, and the water is easy to run off. The existing secondary sedimentation tank has the problems of high investment and operation cost and low separation efficiency, and meanwhile, the three-phase separator has the problem that the ascending air interferes with mud-water separation, so that the existing separation device for water treatment is difficult to realize the function of separating mud and water at low cost and high efficiency. Disclosure of utility model In view of the above, it is necessary to provide a separation device for water treatment, which solves the problem that the conventional separation device for water treatment has difficulty in realizing the function of separating the mud and the water at low cost and high efficiency.
