Embodiment Construction
[0027] The application will be further elaborated by the following examples
[0028] The embodiment of the present invention a kind of method (electroplating wastewater treatment system such as electroplating wastewater dephosphorization) figure 1 shown), including the following steps:
[0029] The electroplating wastewater passes through the hydrolytic acidification tank 101, the activated sludge system 102, the inclined tube sedimentation tank 103, the ozone sedimentation tank 104, the biological aerated tank 105, the Fenton coagulation tank 106 and the chemical sedimentation tank 107, and then discharges up to the standard.
[0030] Specifically:
[0031] Before entering the hydrolytic acidification tank, the electroplating wastewater contains about 20mg / L of phosphorus.
[0032] Hydrolytic acidification pool:
[0033] The hydrolytic acidification tank adopts polyethylene filler to increase the contact area between the waste water and the filler, and the bottom goes in a...

Abstract
The invention relates to a method for dephosphorization of electroplating wastewater. The method includes the following steps: enabling the electroplating wastewater to sequentially pass a hydrolysis acidification tank, an activated sludge system, an inclined tube sedimentation tank, an ozone sedimentation tank, an aerated biological tank, a Fenton coagulating basin and a chemical precipitation tank, and discharging the electroplating wastewater up to the standard. The 'biochemical treatment-advanced oxidation-coagulating sedimentation' processes are integrated for deep treatment of non-positive phosphate in electroplating industry wastewater electroplating plots. By the method, the problem that it is not easy for the phosphorus index of the electroplating plots to reach the standard stably for a long time can be solved, wastewater treatment efficiency and social and economic benefits are improved, and clean production, energy conservation and emission reduction are realized.
Description
technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a method for removing phosphorus from electroplating wastewater. Background technique [0002] In order to promote the development of the electroplating industry, it complies with the work requirements of my country's energy conservation, emission reduction and heavy metal pollution prevention and control. It has become the consensus of various government management departments to thoroughly solve the problems of optimization and upgrading, clean production and pollution prevention in electroplating enterprises, and to promote "centralized construction and centralized pollution control" in electroplating enterprises. The electroplating industrial park gathers electroplating production enterprises with different production processes, and the quality and quantity of the production drainage water has huge fluctuations. If various pollutants are discharged beyond the sta...
