The wastewater produced by refining and chemical industry contains large amount of oil, sulphur and other toxic matters, the simple process can not meet the process requirement, process combination is more suitable, such as filtration, ultrafiltration, activated carbon adsorption, RO and etc., which can get the water quality to meet the required standard. Treatment of refining and chemical wastewater, the priority is analyze the pollutants, identify the substance characteristic and interconnection, avoid direct and indirect pollutions, make sure comprehensive technical treatment of the water.

• Petrochemical wastewater treatment for reuse process
  

  The water consumption of refinery company is increasing and component of the water is more complicated, poor biodegradability and high salt concentrations. The water cost is increasing. So the wastewater advanced treatment for reuse can bring the company economic benefit and relief the water shortage issue.

• Petrochemical wastewater standard discharge technology
  

  Wastewater pre-treatment: The oil content in effluent less than 50mg/L;
