Treatment device for copper-containing wastewater of copper smelting plant

Abstract

The invention discloses a treatment device for copper-containing wastewater of a copper smelting plant. The treatment device comprises a wastewater filter tank, an acid-base neutralization tank and anelectrolytic treatment tank. A first stirring device is arranged in the wastewater filter tank, a storage hopper is arranged on the upper surface of the acid-base neutralization tank, a second stirring device is arranged in the acid-base neutralization tank, a heating plate is fixedly connected to the interior of the acid-base neutralization tank, a direct-current power supply is fixedly connected to the outer side wall of the electrolytic treatment tank, an electrolytic refining device is fixedly connected to the upper end of the direct-current power supply, and a drainage device is arrangedin the electrolytic treatment tank. According to the treatment device for copper-containing wastewater of a copper smelting plant, the purposes of improving the filtering effect and preventing wasteare achieved through the arrangement of the wastewater filtering tank, the purpose of preventing discharged wastewater from corroding external soil is achieved through the arrangement of an acidic material and an alkaline material in the storage hopper, and the purpose of improving the treatment efficiency is achieved through the arrangement of the electrolytic refining device.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a treatment device for copper-containing wastewater in a copper smelter. Background technique [0002] According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, etc., while domestic sewage is sewage produced in daily life, which refers to a complex mixture of various forms of inorganic and organic substances, including: ①floating and suspended solid particles of large and small sizes; ②glue Shape and gel-like diffuser; ③ pure solution. According to the nature of water pollution, there are two types of water pollution: one is natural pollution; the other is man-made pollution. At present, man-made pollution is the most harmful to water bodies. Water pollution can be divided into three categor...

Problems solved by technology

[0003] Wastewater from metal smelters contains a large amount of heavy metals, which is easy to pollute the environment. The existing waste water treatment devices in copper smelters have the following problems: 1. Sometimes the metal particles in the waste water cannot be completely filtered, which is easy to cause waste of resources such as raw materials. 2. 1. The treatment efficiency of copper ions in wastewater is low. 3. Most of the wastewater is acidic or alkaline, and direct discharge is likely to cause serious corrosion to rivers and land
