Industrial wastewater treatment--petroleum and chemical wastewater
Petroleum and chemical wastewater has the characteristics of high salinity, high concentration
of organic matter, unstable pH, numerous biologically difficult to degrade substances, and high
hardness. In order to reduce pollutant emissions and improve water resource utilization, based on
conventional biochemical processes that meet discharge standards, we have successfully
developed a technology for the reuse and zero discharge of petrochemical tail water, which has
been successfully applied in the industry. Reducing pollution emissions, improving water resource
utilization, and achieving high-quality recovery of waste salt are the trends.
Main process
The main process is biochemical + physicochemical + chemical hardening + ceramic membrane +
membrane concentration and salt separation + freezing crystallization.
Technical advantages
· Adopting ceramic membrane technology for impurity removal, with a short process and less
land occupation;
· Adopting salt separation technology to achieve high-quality salt recovery;
· Using frozen crystallization technology to recover sodium sulfate crystals, the product meets
the industrial grade first-class standard.

Industrial wastewater treatment--oily wastewater and waste oil regeneration
A large amount of oily wastewater is discharged during the production process of industries
such as oil extraction, petrochemical, coal chemical, steel, and mechanical processing. In addition,
the regeneration rate of waste lubricating oil in China is less than 10%, and 70% to 90% of the
components in waste lubricating oil can be recycled through recycling and regeneration. JIUWU
HI-TECH overall solution centered on ceramic membranes has been successfully applied to the
treatment of oily wastewater and waste oil regeneration, enabling it to meet the discharge
standards. After advanced treatment, it can achieve the recycling of water resources and waste oil,
and also achieve the resource utilization of waste oil. The main sub areas include: oil and gas field
produced water, fracturing fluid, waste emulsion disposal, coal chemical oil-water separation, and
waste lubricating oil regeneration.
