Industrial heavy metal sewage treatment system

Abstract

The invention relates to the technical field of heavy metal sewage treatment, in particular to an industrial heavy metal sewage treatment system which comprises a tank body, a water inlet pipe penetrates through the upper end of the outer surface of the tank body, a feeding pipe penetrates through the lower end of the outer surface of the tank body, and four supporting columns are annularly, uniformly and fixedly connected to the edge of the upper surface of the tank body; the upper ends of the four supporting columns are fixedly connected with a mounting shell; and the center of the upper end of the inner surface of the mounting shell is fixedly connected with a feeding mechanism. The feeding mechanism comprises a machine shell, a motor, a rotating shaft, a stirring rod, a water pump, a first one-way valve, a box body, an air pump, a pressing plate, rotating blades and a storage box. According to the invention, gas is utilized to drive floccules to move upwards, and the floccules are hung on the water surface by using the rotating blades, so that the floating floccules enter the storage box from the water surface, and the floccules are prevented from precipitating in water; and when the floccules are discharged, the floccules block a blow-off pipeline and a filter screen, so that the working efficiency is improved, and the maintenance cost of the blocked pipeline is reduced.

Description

Technical field [0001] The present invention relates to the field of heavy metal sewage treatment, and in particular, a industrial heavy metal sewage treatment system. Background technique [0002] Heavy metal wastewater treatment refers to the process of removing heavy metals in heavy metal wastewater and recycled or harmless treatment, producing heavy metal wastewater, production in many production in industries such as mine, mechanical manufacturing, chemical, electronics, instrumentation. The heavy metal wastewater is severely polluted, and the heavy metals in human beings are huge. The heavy metals in the sewage can generally not decompose damage, and they need to use heavy metal sewage treatment equipment to transfer their transfer or transform their materialization form, so that it reaches the emission standard Can be emissively or reuse. [0003] China's patent discloses a heavy metal sewage treatment equipment and a heavy metal sewage treatment system. The position is pr...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned heavy metal sewage treatment equipment and heavy metal sewage treatment system, through the pre-discharge bin and two drainage pumps, return the sewage that has not reached the standard and discharge the sewage that meets the standard to the discharge pool. The equipment occupies a small area and is suitable for small-scale heavy metal sewage treatment. However, in the actual use process, the sediment can easily block the filter screen and the sewage outlet, thereby reducing the efficiency of sewage treatment, and the irritating gas generated by the reaction between lye and sewage during the treatment process cannot be effectively filtered and discharged
