Biological treatment of oilfield drainage

Oil-Tech Corporation introduced, absorbed, and improved oversea oil-containing wastewater biological treatment system, and has owned a full set of strain in situ acclimatization technology. If the water contains too much oil with concentration exceeding 100mg/L, an anaerobic process is usually added in the project. In that part, biological emulsion breaking is adopted to recovery most of oil for reducing the burden of subsequent aerobic contact oxidation treatment. Oilfield discharged wastewater biological contacting oxidation (wastewater aerator and anaerotor tank) treatment technology Technological advantage. Low operation cost: after stain acclimatization, the routine cost is only air blower electrical cost and little labor cost; Easy operation and management: during the operation process, only air blower needs monitor and periodic maintenance; Stable water quality: biological treatment system has certain shock load tolerance ability, and basically is not affected by human factors; No secondary pollution: thorough treatment with no addition of chemicals or nutrients; Extremely low maintenance cost: hardly no routine maintenance work.
