Skid-mounted oil production wastewater treatment apparatus

The invention relates to a skid-mounted oil production wastewater treatment apparatus. The skid-mounted oil production wastewater treatment apparatus comprises an apparatus control system, a biochemical pool and a tubular ultrafiltration apparatus, wherein the water inlet of the tubular ultrafiltration apparatus is fluidically connected with the biochemical pool; the concentrated sewage filtered out flows back to the biochemical pool through the water outlet of the tubular ultrafiltration apparatus; a membrane backwash apparatus is fluidically connected with the water inlet of the tubular ultrafiltration apparatus; and the backwash solution backwashed out by the tubular ultrafiltration apparatus flows back to the membrane backwash apparatus through the water outlet of the tubular ultrafiltration apparatus. The skid-mounted oil production wastewater treatment disclosed by the invention has the advantages of being compact in structure, convenient to move, simple to operate, short in effluent cycle, good in effluent quality, capable of saving investment of capital construction, and the like, is mainly used for rapidly removing oil, bacteria and suspended matters in oil production wastewater to enable the effluent quality to achieve the A1-level standards of SY/T5329-94; the speed of the equipment for treating the oil production wastewater after stable running can achieve 3.8 m /h; and good social benefits are generated after successful running.
