Description
Technical Field
The utility model relates to an air-float sludge regeneration device, and belongs to the technical field of sludge regeneration.
Background
The sewage treatment plant adopts the traditional A 2 The sewage treatment process such as O and the like can realize the dephosphorization efficiency of 90 percent by optimizing operation and adding carbon source, and can only marginally reach the first-level A emission standard (less than or equal to 0.5 mg/L). Because the activated sludge processes such as CAST, oxidation ditch and the like have no independent anaerobic area and are subject to the water quality characteristics of low-carbon water inflow commonly existing in China, the biological dephosphorization effect is poor, and the stable standard discharge of total phosphorus in effluent can be realized only by assisting chemical dephosphorization agents. Through the net flocculation reaction and the high-efficiency precipitation technology of the chemical dephosphorization process, the TP concentration can be reduced to below 0.1mg/L, but the consumption of the medicament is huge. With the continuous improvement of the TP standard of the effluent,chemical phosphorus removal is gradually dominant and becomes an indispensable process unit for sewage treatment plants.
Air floatation is a water treatment technology which is being studied deeply and promoted continuously at home and abroad, and compared with the traditional flocculation precipitation dephosphorization process, the air floatation has the characteristics of small occupied area, high equipment integration degree, strong impact load resistance and the like, can realize the ultimate dephosphorization target with TP concentration lower than 0.1mg/L, and has an outstanding application in advanced treatment of sewage treatment plants and surface water treatment. In addition, in order to achieve standard emission, the medicament must be excessively added, resulting in serious waste. The added chemical agent can generate a large amount of chemical sludge, and substances such as residual metal ions in the chemical sludge can also cause a certain harm to aquatic ecology, so that the chemical sludge is neither economical nor environment-friendly, and does not accord with the development direction of sewage treatment under the 'double carbon' target. At present, the conventional method is to dispose chemical sludge and biochemical sludge together, the disposal mode comprises aerobic composting, anaerobic digestion and the like, and metal substances in the medicament can have serious influence on the sludge disposal product and also have secondary pollution risk, so that the disposal and utilization of the chemical sludge generated in the dephosphorization link of the sewage treatment plant are the problems to be solved urgently.
