Heavy metal-containing wastewater treatment system

Abstract

The invention relates to a heavy metal-containing wastewater treatment system. The heavy metal-containing wastewater treatment system comprises a stirring tank, a precipitation tank, a press filteringdevice, a clean water tank, a dissolving device, an extraction and reverse extraction device, an electrolysis device, and a metal storage chamber; the wastewater is firstly sent into the stirring tank, then sent into the precipitation tank, pressed and filtered by the press filtering device, and finally sent into the clean water tank; the obtained sludge after press filtering is sequentially sentinto the dissolving device, the extraction and reverse extraction device and the electrolysis device to be electrolyzed; the obtained metal is stored into the metal storage chamber. The heavy metal-containing wastewater treatment system has the advantages that the input and output ratio is good, the green and environment-friendly effects are realized, the energy consumption is little, and the industrialized scaled production is easily realized.

Description

Technical field [0001] The invention relates to the environmental protection field of waste water treatment, in particular to a heavy metal-containing waste water treatment system. Background technique [0002] With the continuous development of human society, while economic development brings benefits, it also produces a lot of pollution. The rapid increase in industrial "three wastes" and the increase in automobile exhaust emissions, the pollution of heavy metals in soil, water, and plants in the human living environment has become increasingly serious, which has become a prominent ecological problem in the coordinated development of economy, society and the environment. Heavy metals are generally not biodegradable, and once they enter water or soil, they are difficult to remove. They can enter the human body through the food chain and cause many diseases (such as cancer). [0003] Heavy metal pollution is different from the pollution of other organic compounds. Many organic co...

Problems solved by technology

Its wastewater treatment has always been a headache for environmental protection personnel. Because the types and concentrations of heavy metals in wastewater produced by different industries are different, even worlds apart, if you directly imitate or apply traditional processes, there will be poor pertinence, low efficiency, and poor water quality. Issues such as non-compliance
