Description

Integrative filtering pond of carbon film

Technical Field

The utility model relates to the field of water supply treatment, in particular to a carbon film integrated filter tank for advanced treatment of a water supply plant, treatment of a sewage plant and special water treatment.

Background

At present, the advanced treatment of a tap water plant, the treatment of a sewage plant and the treatment of special water are mainly carried out by adopting an ozone biological activated carbon process, and the ozone biological activated carbon process has better removal rate for natural organic matters and ammonia nitrogen in raw water. The form of the biological activated carbon adsorption tank in the ozone biological activated carbon process comprises a downward flow fixed bed and an upward flow fluidized bed. The biological activated carbon adsorption tanks adopting the downward flow fixed bed are more common, but in recent years, the biological activated carbon adsorption tanks of the upward flow fluidized bed are gradually popularized and used. Compared with the traditional biological activated carbon adsorption tank of a downward flow fixed bed, the biological activated carbon adsorption tank of the upward flow fluidized bed has more advantages: the expansion rate of the upward flow activated carbon adsorption tank is good, the expansion rate of the upward flow activated carbon adsorption tank can reach 30% -50%, the higher expansion rate can ensure that the activated carbon fully plays a role, and the removal rate of organic matters is improved; secondly, the use efficiency of the upward flow activated carbon adsorption tank is high, the flow speed is high, and the occupied area is small; thirdly, the head loss of the upward flow activated carbon adsorption tank is relatively small, which is about 1.0 m-1.2 m.

Although the upward-flowing activated carbon adsorption tank has a plurality of advantages compared with the downward-flowing treatment mode, the upward-flowing activated carbon adsorption tank has limited removal effect on granular substances in water, and meanwhile, the risk of microorganism leakage exists. The ultrafiltration membrane treatment technology can efficiently remove granular substances in water, and has an effective removal function on microorganisms. The combination of the two has obvious technical complementarity and application prospect. Currently, there are few practical applications due to lack of suitable pool-type structures and the like.
