After the sewage is filtered, the oil contamination and other purities in the sewage are mainly concentrated on the upper part of the nutshell filter medium layer within the range of 0-100mm, and the oil contamination and other purities on nutshell filter media can be effectively removed much more by adopting a back washing water and gas-combined filter medium regeneration mode.
Description
Technical field
The utility model relates to a kind of waste disposal plant, more particularly it to relate to a kind of nut-shell that adopts be the filtration waste disposal plant of filtration medium.
Background technology
Along with the development of sewage disposal technology, filter the important process link that also just becomes gradually in the sewage disposal, the height of filtering technique level, the quality of filter plant directly has influence on the state of the art and the treatment effect of entire sewage treatment process.In filtering industry, adopt nut-shell to carry out sewage disposal and generally promoted at present as filtrate.
Since nut-shell have adsorptive power strong, cut dirty big, good hydrophilic property, anti-oil immersion, wear resistance is good, hardness is high, proportion is moderate, easy backwash, stable performance, acid and alkali-resistance, regeneration easily, not dosing, adopting nut-shell is that the filtration waste disposal plant of filtration medium has been widely used in land and marine oil field, petrochemical industry refinery, metallurgical oily water treatment; Harbour, harbour, oil depot oily water treatment; Boats and ships, and other oily water treatment.The walnut shell filter waste disposal plant can adsorb too much greasy dirt and other impurity on the nut-shell in use for some time, and its filtration capacity is reduced, and device is imported and exported the pressure drop increase, and discharge water quality is not up to standard.At this moment, need be to the walnut shell filtering material cleaning and regeneration.At present, walnut shell filtering material cleaning and regeneration mode mainly contains following several, single back flush type regeneration, mechanical agitation type regeneration, the regeneration of extracorporeal circulation cleaning type and the regeneration of external scrubbing type.
Retrieval finds that what application number 00254583.7 patent adopted is mechanical agitation type regeneration, mainly is to stir repeatedly by whipping device, makes filter material layer loosening, impels oil and other impurity of adhering on the filtrate to break away from its surface, flows out with backwashing water.The filtrate but this mechanical agitation type regeneration is worn and torn when stirring easily causes and runs the material phenomenon, can not drive all filtrates during stirring, easily forms and hardens, and influences filter effect.The external scrubbing type regeneration of the extracorporeal circulation cleaning type regeneration of application number 03264519.8 and application number 03260552.8 all is by recycle pump filtrate to be extracted out outside the waste disposal plant to clean by collision friction or water flushing, and waste disposal plant is returned in recirculation.Though these two kinds of regenerations can in cleaning process, along with the discharge of rinse water, easily cause the obstruction of running material phenomenon and circulation loop with the filtrate wash cycles, are unfavorable for the steady running of whole device.
Though wear and tear filtrate and circulation loop phenomenon of blocking can not appear in modal single back flush type regeneration, but in the isolated sewage of oil field mining liquid, increased residual polymer, the existence of these polymkeric substance, sump oil and suspended substance in the sewage are adhered on the walnut shell filtering material together with polymkeric substance, be not easy to filtrate and separate.And this filtrate that is stained with sump oil, suspended substance and polymkeric substance is more less than the relative proportion of ordinary filter, when adopting single sewage backwash, the very easy come-up of these filtrates also is adsorbed on the water distributor screen casing, and it is long-pending more thick more, screen casing is stopped up, cause back flushing normally not carry out, thereby filtrate just can not get effective regeneration, the filter effect of strainer just reduces gradually.
Summary of the invention
