Mixed catalyst ultrasonic atomization organic sewage purifying system under ultraviolet condition

Abstract

The invention discloses a mixed catalyst ultrasonic atomization organic sewage purifying system under the ultraviolet condition.The organic sewage purifying system comprises an atomization pond, an atomization pipe and auxiliary equipment, the atomization pipe is arranged in the atomization pond, an air supply fan is arranged on the lower portion in the atomization pond, the upper portion of the air supply fan is sequentially connected with an ultrasound generating circuit and an ultrasound generator, an air inlet pipe is arranged in the gap between the atomization pond and the atomization pipe, a fan is arranged at the end of the air inlet pipe, and the tail of the air inlet pipe leads to the air supply fan; the top of the atomization pipe is connected with a reliquefaction device, and an ultraviolet lamp is arranged in the inner wall of the upper portion of the atomization pipe.The organic sewage purifying system further comprises an organic sewage filtering device and a hydrogen peroxide device which are connected with the bottom of the atomization pipe through pipelines; a pumping pipe is arranged in the gap between the atomization pond and the atomization pipe, one end of the pumping pipe is located at one side of the bottom of the atomization pipe, and the other end of the pumping pipe is connected with a pumping motor.Non-large-scale biochemical sewage can be treated, and the influence on external environment by organic sewage emission is reduced to the maximum.

Description

technical field [0001] The invention relates to a comprehensive treatment and purification device for sewage, in particular to a device capable of processing and purifying organic sewage. Background technique [0002] At present, the treatment of organic sewage mainly uses physical and chemical treatment technology. Physicochemical method is often used as a pretreatment method in the treatment of organic wastewater. The purpose of pretreatment is to recycle useful components in wastewater, or to treat some refractory biodegradable substances, so as to remove organic matter, improve biochemical properties, and reduce biochemical Reduce processing load and improve processing efficiency. Commonly used physical and chemical methods include extraction, adsorption, concentration, ultrasonic degradation, etc. Although each method can purify organic sewage to a certain extent, there are also some disadvantages. For example, the extraction method is only a physical transfer process...

Problems solved by technology

Although each method can purify organic sewage to a certain extent, there are also some disadvantages. For example, the extraction method is only a physical transfer process of pollutants, not the real degradation; although the activated carbon used in the adsorption method has a high adsorption capacity However, due to the difficulty of regeneration and high cost, it is rarely used in China; the energy consumption of the concentration method is relatively high
