Embodiment Construction
[0014] The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing and specific situation:
[0015] Such as figure 1 Shown, the present invention comprises the following steps:
[0016] (1) Removal of large suspended solids or floating solids: pharmaceutical wastewater first removes large suspended solids or floating solids in the wastewater with a particle size greater than 10mm through a grid; the grid is an artificial or mechanical grid, and the size of the grid is Depending on the amount of water, the artificial grid should be cleaned regularly, when the amount of grid slag is 0.2m 3 When / d, use stainless steel or anti-corrosion carbon steel mechanical rotary grille, with a grille gap of 10mm;
[0017] (2) Regulating wastewater: send the wastewater after removing large volumes of suspended solids or floating solids into a regulating tank with a multi-curved surface agitator, and stir for 6-8 hours to improve the...

Abstract
The invention aims at providing a treatment method of traditional Chinese medicine wastewater, which can effectively solve the problems of big engineering investment, high operating cost, inconvenient operation management, bad disposal of residual sludge, secondary pollution such as noise produced by operation of equipment and potential safety hazard in the existing treatment process of traditional Chinese medicine wastewater. The treatment method comprises the following steps: (1), removal of large suspended matters or floating matters; (2), regulation of wastewater; (3), separation of wastewater; (4), oxidation reaction; (5), settling; (6), flocculation and decoloring; and (7), gravity thickening. The treatment method has easy installation of equipment, simple operating method, low cost, good effects and large economic and social benefits, and can effectively solve the problems of big engineering investment, high operating cost, inconvenient operation management, bad disposal of residual sludge, secondary pollution such as noise produced by operation of equipment and potential safety hazard in the existing treatment process of traditional Chinese medicine wastewater.
Description
technical field [0001] The invention relates to wastewater treatment, in particular to a treatment method for traditional Chinese medicine wastewater.
