Embodiment 1

[0070] This embodiment adopts figure 1 The process flow shown.

[0071] 1. Material properties

[0072] (1) Wastewater containing heavy metals: The material is industrial wastewater containing cadmium, nickel, zinc, mercury and other heavy metals produced in industrial production. The content of heavy metals fluctuates within 80-120mg / L, the pH value is between 4 and 5, and the temperature is Room temperature.

[0073] (2) Adsorption particles: Add 2000-3000g adsorption particles per cubic meter of heavy metal wastewater.

[0074] 2. Experimental method

[0075] In the corresponding position of the original pipeline, it is transformed into a newly designed one such as figure 1 The pipeline system shown. During the experiment, the feeding conditions were consistent with those of the original pipeline. When the heavy metal wastewater is fed, the flow rate is 2m 3 / h, observe the newly designed pipeline running continuously for 1 day, observe the treatment effect and throughput.

Abstract

The invention relates to a continuous feeding and pre-mixing method and device for heavy metal wastewater treatment equipment, particularly provides a continuous feeding and pre-mixing method for the heavy metal wastewater treatment equipment and further provides a continuous feeding and pre-mixing device of the heavy metal wastewater treatment equipment.

Description

Technical field [0001] The invention belongs to the field of sewage treatment, and relates to the mixing of sewage and adsorbed particles, and continuous feeding of sewage treatment devices. More specifically, it relates to a continuous feeding and pre-mixing method of a heavy metal wastewater treatment device, and a device used to implement the method. Background technique [0002] Heavy metal wastewater refers to wastewater containing heavy metals discharged from industrial production processes such as mining and metallurgy, machinery manufacturing, chemical engineering, electronics, and instrumentation. Heavy metal (such as cadmium, nickel, mercury, zinc, etc.) wastewater is one of the industrial wastewater that pollutes the environment the most and harms humans the most. Its water quality and quantity are related to the production process. A preliminary investigation revealed that more than 300 million people in my country have unsafe drinking water. As the country pays mor...
