Gold processing sewage treatment device

Abstract

The invention discloses a gold processing sewage treatment device. The device comprises a pretreatment tank, a reverse osmosis tank, a purification tank and a sedimentation tank; a filtering assemblyfor filtering large impurities is mounted in the pretreatment tank; a dirt removing assembly for preventing blockage is mounted above the filtering assembly; a plurality of mounting grooves are formedin the inner wall of the reverse osmosis tank; a detachable reverse osmosis assembly is mounted in each mounting groove; a chemical feeding assembly for preventing chemicals from being dissolved incompletely is mounted in the purification tank; a stirring assembly for assisting dissolution is mounted in the purification tank; according to the invention, the detachable reverse osmosis assembly isarranged, so the damaged filter element can be timely replaced; the air guide pipe and the chemical guide pipe are mounted in the vertical height direction of the purification tank, so that the chemical coverage area is effectively increased, the wastewater treatment quality is improved, the blockage of the filter assembly can be effectively prevented by arranging the dirt removing assembly, and the sewage treatment efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a gold processing sewage treatment device. Background technique [0002] There are two main gold processing techniques, namely the amalgamation method and the cyanidation method. In recent years, with the continuous improvement of gold processing technology and people's increasingly stringent requirements for environmental protection, the amalgamation method has gradually been replaced by the cyanide gold extraction process. However, the cyanide gold extraction process will produce a large amount of cyanide-containing wastewater. This part of cyanide-containing wastewater not only contains a certain amount of highly toxic cyanide, but also contains heavy metal ions such as thiocyanate and copper, zinc, and lead. If If not treated effectively, there will be major environmental hazards. [0003] At present, there are many kinds of devices used for gold processing sewage ...

Problems solved by technology

However, the cyanide gold extraction process will produce a large amount of cyanide-containing wastewater. This part of cyanide-containing wastewater not only contains a certain amount of highly toxic cyanide, but also contains heavy metal ions such as thiocyanate and copper, zinc, and lead. If If not treated effectively, there will be major environmental hazards

[0003] At present, there are many kinds of devices used for gold processing sewage treatment on the market, usually using reverse osmosis membrane to treat sewage, and because most of the reverse osmosis membranes are semi-permeable membranes, long-term use will damage the reverse osmosis membrane, but the existing The technology cannot replace the reverse osmosis membrane very well. In addition, when adding chemicals to the filtered sewage, it is usually put into the sewage through a drug injection port, so that the sewage and the chemicals are not fully dissolved, thereby reducing the sewage treatment. quality, for which we propose a gold processing sewage treatment plant
