Embodiment Construction

[0018] Such as figure 1 As shown, a photoelectric composite biological treatment method and reactor of the present invention are composed of a micro-electrolysis treatment area 1 and a biological treatment area 7, and the micro-electrolysis treatment area 1 is provided with TiO-plated 2 Coated iron-carbon filler 2, the inside of the micro-electrolysis treatment area 1 is provided with a photocatalytic reaction area 5, and the upper part of the micro-electrolysis treatment area 1 is a biological treatment area 7, and in the biological treatment area 7 The biological suspension filler 6 loaded with biological enzymes is provided, and the bottom of the micro-electrolysis treatment area 1 is provided with an aeration device 4. Due to the aeration effect, the microorganisms fully contact with the organic matter in the sewage, and the removal effect of the organic matter is better. A water inlet 3 is provided at the lower end of the treatment reactor, and a water outlet 8 is provide...

Abstract

The invention relates to a reactor for a photoelectric composite biological treatment method. The reactor comprises a container, wherein a micro-electrolysis treatment zone is arranged in the container, an iron-carbon filler with a TiO2 coating is arranged in the micro-electrolysis treatment zone, a photocatalytic reaction zone is arranged inside the micro-electrolysis treatment zone, an aeration device is arranged at the lower part of the micro-electrolysis treatment zone, a biological treatment zone is arranged at the upper part of the micro-electrolysis treatment zone, a suspended filler supported with a biological enzyme is arranged in the biological treatment zone, a water inlet or water outlet is formed at the upper end of the container and a water outlet or water inlet is formed at the lower end of the container. The invention also provides the photoelectric composite biological treatment method of wastewater. According to the photoelectric composite biological treatment method of wastewater disclosed by the invention, by the synergic effect of the micro-electrolysis and biological method, the problems of existing water treatment technology are solved, the treatment effect of wastewater is improved, the treatment efficiency is improved, energy conservation is achieved and the treatment cost is reduced.

Description

technical field [0001] The invention belongs to the fields of environment and biochemical industry, and in particular relates to a wastewater treatment device, in particular to a photoelectric composite biological treatment method and a reactor. Background technique [0002] With the rapid development of the economy, environmental problems have become increasingly prominent, and water resources are in short supply in my country, so wastewater treatment is particularly important. In major chemical plants, industrial water consumption is increasing, the composition is complex, and the biodegradability is poor, which is not conducive to water purification, and the heavy metals contained in it are harmful to human and animal health. [0003] The commonly used micro-electrolysis method is mainly aimed at acidic wastewater, and the pH range of the influent is narrow. In order to achieve a high treatment effect, acid is added to the wastewater, which increases the treatment cost. ...
