Equipment for Oilfield well-flushing wastewater tr

The Flushing fluid of wastewater treatment systems is the wastewater produced by backwashing the injection wells, which has the following characteristics: high color: flushing fluid usually shows the color of dark brown high concentrations of suspended solids the value of pH is high: flushing fluid generally shows the Conditions of Basic the water contains Hexavalent Chromium(Cr6+) and oil According to the above characteristics of flushing fluid, we implement the following treatment process: hydrolysis in the hydrolysis tank→SSF wastewater purification. We did pilot-plant test using SSF wastewater purification technology in No.7 Oil Production Plant of Daqing oil field, achieving a very good treatment effect. This process is relatively simple, cost effective and efficient.
