Description
Technical Field
The utility model belongs to the technical field of waste water treatment, in particular to waste water air supporting processing system.
Background
Industrial wastewater often contains a large amount of suspended substances or dirty oil, and air floatation is one of the methods for effectively removing the suspended substances or the dirty oil from the wastewater. The air floatation principle is that a large amount of micro bubbles are generated by introducing dissolved air water into water, so that the air is attached to suspended particles in a highly dispersed micro bubble form to cause the density to be lower than that of the water, and the air floats on the water surface by utilizing the buoyancy principle, thereby achieving the aim of solid-liquid separation.
In the existing wastewater treatment process, paint water after adding drugs automatically flows into a buffer tank and an air floatation tank from a stirring tank in sequence by gravity, and large-sized flocs are gathered at the positions of pipeline connections and valves to cause clogging; in the process, paint water can be pumped into the buffer tank through a centrifugal pump for improvement, but the centrifugal pump breaks up flocs while conveying liquid due to too high rotation speed of an impeller, so that particles in the buffer tank are too small to coagulate flocs, as shown in fig. 1, and in addition, precipitates still occur in the buffer tank, as shown in fig. 2. Therefore, submersible pumps are not suitable for treating wastewater containing fine particles and flocs.
Disclosure of Invention
The utility model aims at overcoming the defect that prior art exists, providing an improve air supporting efficiency, waste water air supporting processing system of reinforcing air supporting effect.
Realize the utility model discloses the technical scheme of purpose is: an air-floatation treatment system for wastewater comprises a stirring tank, an air-floatation tank, a supernatant storage tank and a biochemical regulating tank which are arranged in sequence; a diaphragm pump is connected between the stirring tank and the air floatation tank; a scum board is arranged in the air floatation tank, and the air floatation tank is connected with a lower clear liquid storage tank through a pipeline; the supernatant storage tank is provided with two bell mouths, one of the bell mouths is connected with the biochemical regulating tank through a valve and a pipeline, and the other bell mouth is connected with the distillation tank through a valve and a pipeline; the distillation retort is connected with the biochemical regulating tank through a pipeline.
The technical proposal also comprises a medicine adding tank; the medicine adding tank is arranged on one side of the stirring tank and is connected with the stirring tank through a pipeline.
In the technical scheme, a medicine adding port is formed in the inlet position of the diaphragm pump; the medicine adding port is connected with the medicine adding tank.
