Walnut Shell Filter Impeller And Backwashing Mode Technology Research

Due to the wastewater containing polymer and normal temperature gathering and transferring,Walnut shell filter material in oily wastewater treatment process caused by pollution,regeneration difficulty,replacement cycle is short,and other issues.Oilfield in recent years,the company in terms of internal structure and the back-flushing filtering tank parameters are improved and optimized,although after renovation of wastewater treatment can reach water indicators,but part of the sewage plant filter after the water quality is not stable,at the same time,through conventional stirring paddle,walnut shell filter material after backwashing filter material expansion easy blocking screen,cause the backwash pressure-out,and filter material regeneration effect is not obvious,the drop in quality of sewage treatment,increasing the difficulty of oil field management,affecting the oilfield development effect.So to seek a suitable for oil field production and the wastewater quality characteristics of efficient,fast and low cost of investment,low running walnut shell filter backwashing regeneration technology,is a technical problem to be solved.We through the development of walnut shell filter material and regeneration technology research on pollution,optimizing the way of effective backwash and suitable for field production operation parameters,to prolong the service life of the walnut shell filter material,replacement cycle to provide technical basis.
