Problems solved by technology

[0002] Emulsion wastewater is a common wastewater in factory production, which is characterized by a wide variety, COD cr and oil content are high, and the treatment is difficult; at present, the commonly used waste emulsion treatment technologies include heating method, salting out method, coagulation method, acidification method, etc. These methods are only suitable for treating a certain kind of waste emulsion; but in actual treatment In the process, there are often many types of emulsions and complex components, such as: emulsion wastewater, electroplating wastewater, landfill leachate, etc., using a single method cannot achieve centralized treatment, and cannot achieve ideal demulsification and COD degradation.

Abstract

The invention discloses a high-COD (chemical oxygen demand) and multi-variety waste emulsion breaking device and breaking method. The device comprises a heat exchanger and a reactor, a first adjusting tank and a plate-and-frame filter press which are connected with the heat exchanger in sequence. The method comprises the eight steps of acidizing, emulsion breaking, PH value adjusting, flocculating, adjusting, filter pressing, cooling and constant temperature maintaining. The device and the method have the beneficial effects that centralized treatment of various emulsification wastewater can be achieved; the treatment difficulty of the emulsion wastewater is reduced to a great extent; the breaking effects of high-concentration and multi-variety emulsions are effectively ensured; the effluent can be ensured to meet the requirements of subsequent biochemical treatment; meanwhile, the labor intensity of workers is reduced, and the economic benefits of enterprises are increased.
