Combined apparatus for advanced treatment of high concentration organic waste water

Abstract

The invention relates to a combined apparatus for advanced treatment of high concentration organic waste water. The apparatus comprises a pretreatment buffer tank, an anaerobic reactor, a pressurized aeration stirring system, a photocatalytic reactor, a filter chamber, a backwashing system, a back flow line pipe system and the like. Preliminary treatment of high concentration organic waste water is carried out by using an anaerobic method after waste water is pretreated, then advanced treatment of primary treated water is carried out by using a photocatalysis method, and furthermore, effluentis filtered with the filter chamber. The apparatus provided in the invention can both profoundly remove high concentration organic matters and ferro-manganese ions in waste water and prevent secondary pollution, has the advantages of small energy consumption, high efficiency, a good effect and the like, is applicable to treatment of high concentration organic waste water and can guarantee stable and highly efficient water yielding and the quality of reused water.

Description

[0001] technical field [0002] The invention relates to a treatment device for high-concentration organic wastewater, in particular to a bioreactor and photocatalytic combined device for advanced treatment of high-concentration organic wastewater. Background technique [0003] With the continuous deepening of people's understanding of anaerobic treatment process, anaerobic biological treatment technology has become one of the important means of treating organic wastewater. Anaerobic biological treatment technology refers to the process of converting various organic substances in wastewater into methane, carbon dioxide and other gases by using the life activities of anaerobic microorganisms under the condition of no molecular oxygen. Compared with aerobic biotechnology, anaerobic biotechnology has the advantages of less energy consumption, less sludge output, potential energy such as methane production, and the ability to treat high-concentration organic wastewater. It is an...

Problems solved by technology

In terms of high efficiency and stability, the current photocatalytic devices often have the following defects: 1. A single ultraviolet light source cannot take into account the water quality treatment in the entire reactor, making the effluent water quality unstable and part of the ultraviolet light in the reactor. In the process of water treatment, it scatters outside the reactor, which not only wastes electric energy, but also reduces the processing efficiency of the reaction device; 2. After the ultraviolet lamp works for a long time, the temperature of the lamp tube rises greatly, which affects the processing efficiency 3. Under aerobic conditions, the processing capacity of the reaction device can be greatly improved, but if an aeration device is installed in the photocatalytic reaction device, not only the structure of the reaction device is complicated, but also the aeration cannot be uniform, which affects Stability of effluent quality
