Embodiment Construction
[0026] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:
[0027] like figure 1 Shown, the combined biological treatment method of a kind of high-concentration COD chromium-containing electroplating cleaning wastewater of the present invention, the COD concentration in the electroplating cleaning wastewater ≥ 2000mg / L, hexavalent chromium concentration ≤ 10mg / L; The processing method includes as follows step:
[0028] (1) The waste water is first sent into the regulating tank for homogenization and equalization;
[0029] (2) The effluent from the regulating tank is sent to the primary filter unit to remove large particles of insoluble impurities in the wastewater;
[0030] (3) The effluent from the primary filter unit is sent to the oxidation unit; the oxidation unit adopts heterogeneous catalytic oxidation, under normal temperature and pressure and under the action of a catalyst, the complex organic po...
