Comprehensive Utilization of Copper Etching Liquid Waste Project
Comprehensive utilization of copper etching liquid waste project
This project has created a precedent for the utilization of domestic hazardous waste resources with a copper recovery rate of 99% or more which can be prepared for a variety of copper and salt products and achieve ammonia emissions. The project was elected to the national key promotion program of scientific and technological achievements.

The Set of Equipment Used for the Extraction and Impurity Removal of Nickel Containing Solutions
With the creation of secondary battery recycling, we successfully developed extraction equipment for the separation of copper, cadmium and zinc from nickel-containing solutions and extracted nickel. The benefits are easy installation, good separation effect , easy operation , stable operation and low treatment costs.
Continuous Electrodeposition Process for Recovering Precious Metals
The tanks used in a series continuously feed the single independent cell cycle electric product process to treat noble metal containing wastewater. This greatly enhances the electrical product efficiency, turns previous batch production into stable and continuous production and expands the range of industrial applications for electrochemical reactors.
Comprehensive Utilization of Phosphorus Containing Acid Waste
Phosphorus wastewater can be treated to produce high purity phosphate products. This project received the second place award for the Shenzhen Municipal Science Technology Progress and the third place award for Shenzhen municipal SASAC independent innovation.
Low Chloride and Low Apparent Density of Copper Oxide Technology
he technology for recovering copper etching liquid waste produces a regular sphere, liquidity, low chlorine and low apparent density of copper oxidation products (CL < 30 mg / kg, apparent density < 1.4 g / cm3), for the preparation of high-end copper powder in the catalyst and battery electroplating industry.[/fusion_text][fusion_separator style_type="none" top_margin="10" bottom_margin="10" sep_color="" border_size="" icon="" icon_circle="" icon_circle_color="" width="" alignment="center" class="" id=""/][/fusion_builder_column][fusion_builder_column row_column_index="5_6" type="1_1" last="yes" spacing="yes" center_content="no" hide_on_mobile="no" background_color="" background_image="" background_repeat="no-repeat" background_position="left top" border_position="all" border_size="0px" border_color="" border_style="" padding="" margin_top="" margin_bottom="" animation_type="" animation_direction="" animation_speed="0.1" class="" id=""][fusion_text]
Electrolysis Technology and Equipment for High Cyanide Liquid Waste
Our company developed the radiation type electrode electrolysis reactor which is suitable for the electrolysis of high cyanide waste liquid. The reactor has easy and safe operation, a low treatment cost and a high recovery rate of gold and silver, copper and zinc.
Demonstration Project of Recycling and Disposal of CFCs Refrigerant
Under the guidance of the Ministry of Environmental Protection and the Shenzhen City Habitat Environment Committee, we used foreign key equipment and built a domestic first cover CFCs refrigerant on-site recycling, decontaminating and regenerating plant to handle the disorderly discharge of South China CFCs class refrigerants which cause the destruction of the ozone layer and exacerbate the greenhouse effect issues. Through the whole process we are able to decontaminate and repurpose the CFCs refrigerants. This project serves as a model in the industry.
