Small-sized integrated advanced oxidation combined treatment system for organic wastewater

Abstract

The invention relates to a small-sized integrated advanced oxidation combined treatment system for organic wastewater. The invention discloses the small-sized integrated advanced oxidation treatment system for the organic sewage. The system comprises a water pump, a backwashing filter, a liquid storage tank, an ultrasonic generator, a parallel self-excited oscillation impinging stream cavitator, aself-excited oscillation efficient miscible device, an atmospheric pressure ionization discharge device, an oxygen generator, a high-frequency high-voltage power supply, a switching valve, an overflow valve, a pressure gauge, a gas flowmeter, a liquid flowmeter, a COD online detector, a pH meter and a thermometer. A modular structure is adopted, and the overall structure is compact. Wastewater pretreatment, self-excited oscillation impinging stream, gas-liquid miscible mass transfer and atmospheric pressure ionization discharge technologies are combined to treat organic wastewater, a circulating working mode is adopted, the defects of a traditional treatment method and a single treatment method are overcome, the cost effectiveness is high, and environmental friendliness is achieved.

Description

technical field [0001] This patent relates to the field of organic wastewater treatment, especially the combination of wastewater pretreatment, self-excited oscillating impact flow, gas-liquid miscible mass transfer and atmospheric pressure ionization discharge technology to treat organic wastewater, and proposes a small-scale integrated advanced oxidation organic wastewater treatment system. Background technique [0002] With the rapid development of urbanization and society. This has greatly increased the amount of industrial, agricultural and domestic water and sewage discharge, but the relative lag of wastewater treatment facilities has caused a large amount of wastewater to be discharged directly without treatment, resulting in a great threat to the surrounding environment and human life. In the field of oily wastewater treatment, oily substances mostly exist in the form of emulsified oil, dispersed oil, and adsorbed oil in wastewater. In this form, the oil is suspend...
