Example Embodiment

[0026] Example 1

[0027] The organic matter in the wastewater is trichloropropane with a concentration of 800 mg / l.

[0028] The reactor 1 includes: a shell 2, an ultrasonic generating device 3, a focusing reflector 4, a water inlet pipe 5, and a water outlet 6 (see figure 1 , figure 2 ).

[0029] The shell 2 of the reactor 1 is a box, and the height of the box is 0.5 meters. The cross section of the box is composed of two parts. The left part is a rectangle with an unsealed right end. The length of the rectangle is 0.6 meters and the width is 0.5 meters. The right part is a parabola with an opening to the left, passing through the apex of the parabola. The axis of is parallel to the length side of the rectangle on the left and is at the midpoint of the width side of the rectangle. With the vertex of the parabola as the origin (0, 0), the shape of the parabola is y 2 =-0.6x, the focus of the parabola is at (-0.15, 0), the rectangle and the parabola are butted at (-0.104, 0.25),...

Abstract

The supersonic process of treating organic waste water is completed inside one ultrasonic reactor comprising casing, ultrasonic generator, focusing reflection plate, water inlet pipe and water outlet pipe. The ultrasonic generator sends out parallel ultrasonic wave, the focusing reflection plate in parabolic cylinder shape focuses the parallel ultrasonic wave to the focus line, and organic waste water enters to the reactor in the place near the focus line to have its organic matter degraded under the action of ultrasonic wave, with the treated waste water being exhausted from the reactor continuously. The present invention has raised ultrasonic energy-to-cavitation energy converting efficiency and cavitation energy utilizing rate, lowered treating power consumption and raised organic matter eliminating effect.

Description

technical field [0001] The invention relates to a method for treating waste water, in particular to a method for treating organic waste water by ultrasonic waves. Background technique [0002] Many industrial production processes will produce a large amount of production wastewater, some of which are organic wastewater that has a great impact on the environment and is difficult to treat. There are many types of organic wastewater, such as organic chloride wastewater, organic phosphide wastewater, etc. Among them, organic chloride wastewater is organic wastewater produced by various industrial production processes, which has the characteristics of large production volume, high stability, and difficult biodegradation. The direct discharge of organic wastewater will cause serious environmental pollution. The development of new and efficient wastewater treatment technology or pretreatment technology is the current development direction of organic wastewater treatment technology....
