High-difficulty wastewater treatment device

Abstract

The invention provides a high-difficulty wastewater treatment device, which is characterized by comprising a wastewater storage tank and a wastewater treatment device, wherein the wastewater treatmentdevice comprises a closed reaction container, a catalyst applied to the inner wall of the container, an ultraviolet lamp at the top of the container, a water storage tank arranged at the bottom of the closed reaction container and an iron carbon filler arranged at the bottom of the water storage tank, wherein a liquid inlet and an air inlet are formed in the top of the closed reaction container,and the liquid inlet is connected with a raw water storage tank through a hose; a plurality of spray nozzles are arranged at the liquid inlet, and the bottom of the closed reaction container is provided with a reflux inlet; the reflux inlet is connected with the wastewater storage tank through a reflux hose, and one side of the closed reaction container is provided with a gas exhaust chimney; a plurality of spray inlets are formed in both sides of the closed reaction container. The device is compact in structure, and does not require a separate ozone device. The utilization rate of hydrogen peroxide is extremely high, the primary energy consumption can achieve a variety of functions to synergistically degrade the organic matter in the wastewater, and the treatment effect is good without secondary pollution.

Description

technical field [0001] The invention relates to waste water treatment equipment, which belongs to the field of environmental chemical industry, and in particular to high-difficult waste water treatment equipment. Background technique [0002] With the rapid development of petrochemical, plastic chemical, electronic chemical and other chemical industries, toxic, harmful and refractory industrial organic wastewater is produced. Improper treatment of these industrial wastewater will bring great harm to the ecological environment and human health, especially The types and volumes of wastewater containing high concentrations of organic matter are increasing, and the pollution of water bodies is becoming more and more serious, threatening people's health and safety and damaging the environment. High-concentration organic wastewater mostly refers to wastewater with a COD concentration above 2000mg / L, which mainly has the following characteristics: First, the concentration of organi...
