Novel TFT-LCD organic wastewater treatment equipment

Abstract

Novel TFT-LCD organic wastewater treatment equipment mainly comprises a waste liquid gathering tank, an ozone pre-oxidation device, a neutralization basin, a hydrolysis pool, a first-stage nitrification and denitrification device, a second-stage anoxic-aerobic device and a sedimentation basin, which are connected successively. The ozone pre-oxidation device comprises several ozone pre-oxidation reaction tanks which are connected in series. The first-stage nitrification and denitrification device comprises a first-stage denitrification tank and a first-stage nitrification tank. The second-stageanoxic-aerobic device comprises a second-stage anoxic tank and a second-stage aerobic tank which are successively connected. The equipment has the following advantages: the structure is designed scientifically; the system operation is stable; and the effluent quality reaches the standard. The equipment is suitable for promotion.

Description

technical field [0001] The invention relates to the field of organic wastewater treatment, in particular to a novel TFT-LCD organic wastewater treatment device. Background technique [0002] As the mainstream technology of flat panel display, TFT-LCD has achieved high economic benefits in production, but at the same time, a large amount of high-concentration high-molecular organic wastewater is also produced in the production process. Therefore, while obtaining good economic benefits, it is also necessary to consider Environmental protection issues, so this part of the production wastewater must also be treated in consideration of its water quality characteristics, otherwise it will greatly affect the environment, and even affect human health because it contains toxic substances. [0003] Due to the complex composition of the production wastewater, high concentration of pollutants, and toxicity, there are many treatment processes on the market, such as multi-stage aerobic tr...

Problems solved by technology

[0002] As the mainstream technology of flat panel display, TFT-LCD has achieved high economic benefits in production, but at the same time, a large amount of high-concentration high-molecular organic wastewater is also produced in the production process. Therefore, while obtaining good economic benefits, it is also necessary to consider Environmental protection issues, so this part of the production wastewater must also be treated in consideration of its water quality characteristics, otherwise it will greatly affect the environment, and even affect human health because it contains toxic substances

[0003] Due to the complex composition of the production wastewater, high concentration of pollutants, and toxicity, there are many treatment processes on the market, such as multi-stage aerobic treatment + ultraviolet sterilization, air flotation device + chemical precipitation and many other processes, but its characteristics are many. Because the process is cumbersome and complicated, due to the uncoordinated proportion of water quality components and the instability of the biochemical system, the chemical precipitation method needs to add a large amount of chemicals, transform other substances, and reprocess.
