High-pressure Desorption Electrolysis
This series of equipment is oriented to the gold-loaded carbon in the gold cyanide carbon slurry process for gold desorption and electrolysis, and the gold adsorbed on the gold-loaded carbon is produced in the form of high-grade gold mud.
This series of equipment has 3 patented technologies and 5 proprietary technologies. Sodium cyanide is not used in the desorption liquid, which reduces the lean carbon grade below 100g/t. The key technology of this equipment is to ensure the balance of metal content, avoid the phenomenon of equipment "accumulation" and "floating gold", and ensure the stable and stable technical indicators of the equipment. The cost is low, and the content of technological advancement has been broadcast on the Spark Science and Technology column of CCTV in 2000. The technology passed the technical appraisal in 2003 and won the second prize of Science and Technology of the China Gold Association. The overall technical level is domestically leading. In 2006, it was designated as an energy-saving technology for gold production by the National Development and Reform Commission. In 2007, it was designated as an industry standard equipment by the National Development and Reform Commission. The equipment has obtained 3 Chinese patents, the patent numbers are: 01241537.5 01241538.5 200620029209.1

The core technology of the reused water and upgrading project adopted Tsinghua University's scientific and technological breakthroughs in bio-ceramic contact oxidation technology and Changzhou Aisite Electrosorption patented technology. The 10,000 tons/day water reused after the electric adsorption is upgraded meets the chemical production process water standard and can be used as process water, boiler supplemental water, and the like. The electro-adsorption device can increase the suspended solids from 10 mg/L to 3 mg/L, the turbidity from 10 NTU to 1 NTU, the ammonia nitrogen from 10 mg/L to 5 mg/L, and the CODCr from 25 mg/L to 10 mg/L. Rise. After the plant is put into operation, it can reduce the emission of CODCr9293 tons, BOD54,454 tons and ammonia nitrogen, 1560 tons per year for Taihua, effectively improving the quality of regional water bodies, and at the same time, it will help ease the pressure of water supply in the severely water-scarce city of Taiyuan.
The process is original and internationally advanced. It has features such as simple pretreatment, low power consumption and operating costs, long equipment life, simple operation and management, and wide application range. The salt removal rate is greater than 75%, and the water recovery rate is up to Above 75%, the electricity consumption is 1 kWh/ton water, and the cost of water production is low. The cost per ton of high quality reclaimed water is 1.95 yuan (the cost of fresh water for Taihua Industry is 3.4 yuan/ton).
It is understood that due to the inadequacy of industrial wastewater treatment, the country’s chemical companies have lost 2 trillion cubic meters of industrial wastewater every year, which has not only wasted precious water resources, but also caused serious pollution to the environment.
The first set of 10,000-ton sewage treatment electric adsorption device was put into operation
On July 27th, the first domestic large-scale sewage treatment 10,000 tons/day water reuse upgrading project - 10,000-ton electric adsorption device was completed and put into production at the Taiyuan Chemical Industry Group Co., Ltd. water plant. The technology has the promotion value in the utilization of sewage in the chemical industry and is expected to create an annual profit of 8.8 million yuan for Taihua.
