Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment and discharge devices, in particular to a cyanide-containing wastewater treatment and discharge device. Background Art

[0002] Cyanide-containing wastewater is highly toxic. Direct discharge will seriously affect the ecological environment and pose a serious threat to the surrounding domestic water. Therefore, the cyanide-containing wastewater needs to be treated before it can be discharged, thereby reducing the impact on the environment. At this time, a cyanide-containing wastewater treatment and discharge device is required for auxiliary treatment.

[0003] In actual work, the structure and function of the existing cyanide wastewater treatment and discharge device are relatively complete and can basically meet the daily use needs, but there are still the following two problems:

[0004] 1. In actual use, cyanide wastewater is treated by chemical methods, that is, reactants are used to fuse with wastewater, and then the cyanide-containing substances inside are reacted and converted into non-toxic or low-toxic substances. This process consumes a large amount of high-concentration reactants. The large-scale use of high-concentration reactants will cause new pollution caused by unreacted reactants;

[0005] 2. When using reactants and wastewater, the reactants are easy to precipitate, resulting in uneven distribution of the reactants in the treatment tank, which makes the reaction not thorough enough and the treatment of cyanide-containing substances not complete.

[0006] Therefore, the utility model provides a cyanide-containing wastewater treatment and discharge device. Utility Model Content

[0007] The purpose of the utility model is to solve the shortcomings in the prior art and provide a cyanide-containing wastewater treatment and discharge device.

At the same time, under the action of the transmission rod, the stirring rod can be driven to rotate, and then the stirring rod can drive the reactant to mix and react with the cyanide-containing wastewater, thereby improving the reaction efficiency.

[0016] The technical effect of adopting the above-mentioned further scheme is: under the action of the circular clamp block and the circular clamp frame, it can be combined with components such as the threaded plug rod so that the clearing rod can be fixed to the stirring rod, so that when the stirring rod rotates, it can drive the clearing rod to rotate, thereby clearing the reaction particles accumulated inside the water outlet at the bottom to avoid clogging the water outlet.
