Combined device for organic chemical laboratory wastewater treatment

Abstract

The invention discloses a combined device for organic chemical laboratory wastewater treatment. Organic laboratory wastewater to be treated sequentially passes through four cylinder purification devices including a macroporous resin adsorption device, an iron carbon microelectrolysis device, a BDD electrolysis device and a photocatalytic device. The macroporous resin adsorption device is providedwith a cylinder wrapping macroporous resin for adsorption and comprises a wastewater inlet, a purified water outlet and a valve for controlling opening and closing of water flow in the water inlet andthe water outlet. The iron carbon microelectrolysis device comprises a cast iron electrode and a carbon rod. The BDD electrolysis device comprises a boron-doped diamond thin film electrode plate (BDD) and a power plug. The photocatalytic device comprises a photocatalyst, an ultraviolet lamp and a quartz glass protective cover. The BDD electrode and the ultraviolet lamp are both connected to a laboratory power source. The combined device has the advantages of simple operation, simple maintenance, energy saving and low cost and scientific and high efficiency in the treatment of the organic laboratory wastewater.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a combined device for organic chemistry laboratory wastewater treatment. Background technique [0002] The chemical wastes produced in organic chemistry laboratories are mainly organic waste liquids, some of which are toxic, such as high concentrations of xylene and chloroform, which can damage the human immune system and cause human dysfunction. Some organic waste liquids are highly corrosive because of their high concentration of waste acid and waste alkali. If these waste liquids are discharged at will, it will not only pose a serious threat to the environment and human health, but also set a bad example for students. Compared with industrial wastewater, organic laboratory wastewater has many types and is prone to chemical reactions. Because of these characteristics, it brings a lot of trouble to the follow-up processing. The use of traditional water treatment metho...

AI Technical Summary

Problems solved by technology

For example, the classic activated carbon adsorption can effectively purify water, but as time goes by, the carbon adsorption capacity will continue to weaken, and it needs to be cleaned and replaced regularly, and it cannot degrade and oxidize organic pollutants, which may lead to phase transfer and cause problems. further deterioration

Chemical methods include oxidation treatment, neutralization treatment, coagulation treatment, etc., which have the ability to quickly and effectively remove pollutants. However, in actual operation, there may be problems such as difficult recovery and easy to produce secondary pollution.

In contrast, the biological method has become one of the most popular water treatment technologies due to its economy and environmental protection. Wastewater is difficult to obtain the ideal degradation effect

Moreover, the improvement of biological treatment effect is difficult to grasp and the uncertainty is high
