Embodiment 1
[0032] Cold rolling thick oil wastewater mainly includes emulsion wastewater and thick oil alkali wastewater. The water quality is as follows: COD is 18000mg / L, oil content is 10000mg / L, SS is 5000mg / L; thin oil wastewater mainly includes thin oil alkali wastewater , the water quality is as follows: COD is 3000mg / L, oil content is 400mg / L, SS is 3000mg / L.
[0033] The above-mentioned dense oily wastewater is pretreated through a grease trap, a paper tape filter, and a ceramic membrane ultrafilter in sequence. Use a grease trap to collect dense oily wastewater, and use the oil skimming device in the grease trap to recover the upper oil slick; paper tape filtration is a security process for ceramic membrane separation, which can remove a part of suspended impurities, foam and sludge, which is very important for the operation of ceramic membranes. To optimize the effect; while the inorganic ceramic membrane uses the principle of sieving and filtration to intercept small particles...
