Specific phosphorus-containing wastewater treatment device for phosphorus chemical industry

Abstract

The invention provides a specific phosphorus-containing wastewater treatment device for phosphorus chemical industry. According to a water flowing direction, the device comprises a raw material receiving device, a comprehensive reaction device, an organic phosphorus precipitation device, an inorganic phosphorus precipitation device, a heat device, a triple effect evaporation device and a centrifugal separation device. According to the device, on the one hand, partial phosphorous ions in phosphorus-containing wastewater can be removed by adopting chemical changes, the concentration of phosphorous ions in the wastewater can be reduced, and remained phosphorous ions in the wastewater are treated in the inorganic phosphorus precipitation device, so that the dosage of chemical agents can be greatly reduced, output of chemical sludge can be reduced, and chemical cost can be reduced; and on the other hand, the phosphorus-containing wastewater is subjected to double phosphorus removal by adopting physical changes, and the efficiency for removing phosphorus can be greatly improved.

Description

technical field [0001] The invention relates to the field of phosphorus chemical industry wastewater treatment, in particular to a phosphorus chemical wastewater treatment device dedicated to phosphorus chemical industry. Background technique [0002] With the development of the country's economy and the improvement of people's living standards, LCD panels have been widely used in various electrical appliances, such as LCD TVs, LCD displays, and LCD advertising screens. However, a large amount of Phosphorus-containing wastewater, if the phosphorus-containing wastewater is not treated up to the standard, it will be discharged. If the phosphorus element in the water exceeds the standard, the eutrophication of the water body will be accelerated, which will bring great harm to people and the environment. Therefore, the phosphorus-containing wastewater must be treated in a harmless manner before it is discharged to avoid harm to humans and the environment. The traditional phosph...

AI Technical Summary

Problems solved by technology

Because the above-mentioned process needs to remove both phosphorus and other pollutants in the wastewater in one treatment process, a large amount of chemicals need to be invested, a large amount of chemical sludge is generated, the cost of chemicals is high, and the removal efficiency of phosphorus is not high

[0003] Moreover, the phosphorus content of the discharged phosphorus-containing wastewater is still relatively high, which is still relatively harmful to people and the environment. Therefore, a high-efficiency phosphorus-containing wastewater treatment device dedicated to phosphorus chemical industry that includes both chemical changes and physical changes is needed
