Treatment device for wastewater containing organic pollutants

Abstract

The invention relates to a treatment device for wastewater containing organic pollutants. The treatment device comprises a liquid storage tank, a circulating pump, a first adsorption tank, an ultrasonic treatment tank, a photocatalytic tank and a second adsorption tank, which are successively connected through pipelines. An adsorption material is arranged in both of the first adsorption tank and the second adsorption tank. An ultrasonic transducer is disposed on an inner wall of the ultrasonic treatment tank, and is connected to an ultrasonic generator outside the ultrasonic treatment tank. The photocatalytic tank is a transparent cylindrical reactor, and is placed under sunlight or artificial light source. Photocatalyst-loaded hydrogel is arranged in the photocatalytic tank. By integrating various treatment methods, organic pollutants in wastewater can be thoroughly degraded. The device of the invention has a wide range of application and has high treatment efficiency.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a treatment device for wastewater containing organic pollutants. Background technique [0002] With the rapid development of the economy, the environmental damage is becoming more and more serious. Water pollution is one of the most important environmental pollution problems. Industrial wastewater and domestic water are the main sources of water pollution in my country, especially in related industries such as petroleum coking, metallurgy and chemical industry. Wastewater of organic pollutants has a large amount of water, complex components, and poor biodegradability, causing huge environmental pressure.

[0002] With the rapid development of the economy, the environmental damage is becoming more and more serious. Water pollution is one of the most important environmental pollution problems. Industrial wastewater and domestic water are the main sources of water pollution in my country, especially in related industries such as petroleum coking, metallurgy and chemical industry. Wastewater of organic pollutants, with a large amount of water, complex components, and poor biodegradability, causing huge environmental pressure

[0003] The current treatment methods for organic polluted wastewater mainly include adsorbent adsorption, ultrasonic degradation, membrane separation, chemical oxidation degradation, microbial degradation, etc., but the degradation of a single treatment method is often not complete enough.

Among them, the photocatalytic method in chemical oxidation degradation has fast degradation speed, no secondary pollution, mild reaction conditions, and obvious application advantages; in the prior art, TiO 2 The representative oxide-type photocatalyst has excellent catalytic performance and stable chemical performance, but it is prone to carbon deposition and deactivation during the catalytic degradation process, and the photocatalyst is easy to aggregate and difficult to recycle.
