Adding a head, the top of the processing chamber is provided with lighting equipment, the wall of the processing chamber is provided with a connecting hole, and connecting pipes are installed on the connecting hole, and different processing chambers are connected through connecting pipes; the lower part of the bottom plate is provided with a gate. The invention provides a device for treating industrial copper-containing sewage, which has the characteristics of low cost, outstanding sewage treatment effect, and is suitable for mining environment and the like.

Description

technical field [0001] The invention relates to the field of biological treatment of water, waste water or sewage, in particular to a device for treating industrial copper-containing sewage. Background technique [0002] Copper compounds exist in a monovalent or divalent state. In natural water, the amount of dissolved copper decreases with increasing pH. When the pH value is 6-8, the solubility is 50-500 μg / L. When the pH value is less than 7, basic copper carbonate [Cu 2 (OH) 2 CO 3 ] is the maximum solubility; when the pH value is greater than 7, the solubility of copper oxide (CuO) is the maximum, at this time, the form of dissolved copper is Cu 2 +, mainly CuOH+; when the pH value rises to 8, Cu(CO 3 ) gradually increased. The adsorption of copper by solid substances in the water body can reduce the dissolved copper, and the existence of some complex ligands can increase the dissolved copper. The measured results of copper content in natural water samples from a...
