Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
This waste disposal plant is the subsequent disposal to city domestic sewage treatment plant discharge water, to satisfy the needs of oil field prepared polymer water.This device comprise with centrifuge separator 1 UNICOM come water storage tank 15, and come water storage tank 15 by pipeline successively with pump D14, disc filter 3, accurate filter E4,4A molecular sieve 5 and accurate security personnel's strainer 6 with go out water storage tank 8 UNICOMs, go out water storage tank 8 again respectively with join poly-working shaft 7 and pump A9 UNICOM; And pump A9 respectively with regenerated reactor 12 and disc filter 3 UNICOMs; Regenerated reactor 12 passes through accurate filter F11 and pump B10 and 4A molecular sieve 5 UNICOMs again respectively, passes through pump C13 and centrifuge separator 1 UNICOM.And centrifuge separator 1 and come water storage tank 15 and disc filter 3, join poly-working shaft 7 and go out water storage tank 8, pump A9 and disc filter 3 and the pipeline of 1 of regenerated reactor 12, regenerated reactor 12 and pump C13 and 4A molecular sieve 5 and centrifuge separator on check valve 2 all is installed.
The process of this waste disposal plant treating water is divided into discharge water processing, disc filter 3 back flushinges, 5 regeneration of 4A molecular sieve, regenerated liquid slagging-off several Control process.
At first to the water of the city domestic sewage treatment plant discharging water storage tank 15 of after centrifuge separator 1 separates, coming in, the discharge water that comes water storage tank 15 to store enters the particle that disc filter 3 is removed greater than 100 microns after pump D14 pressurization, then enter accurate filter E4 filtering greater than 5 microns particle, enter 4A molecular sieve 5 then and remove high valence ion, enter out water storage tank 8 by precision security personnel strainer 6 again, go out water storage tank 8 and join poly-working shaft 7 UNICOMs, can outwards pump oil recovery prepared polymer water as required.When adhering to dirt and need clear up on the disc filter 3, want regularly back flushing, backwash water is from going out water storage tank 8, ejector priming A9 opens corresponding valve on the pipeline with disc filter 3 UNICOMs, from the water that goes out water storage tank 8 disc filter 3 is carried out back flushing, water after the back flushing 1 pair of solid particulate of centrifuge separator of can flowing through carries out centrifugal back and separates automatically, and isolated water imports water storage tank 15.After the filtrate on the 4A molecular sieve lost efficacy, need carry out the 4A regenerating molecular sieve handles: prepare regenerated liquid earlier, process be ejector priming A9 open with regenerated reactor 12 UNICOM's pipelines on corresponding valve in regenerated reactor 12, inject quantitatively from the water that goes out water storage tank 8, in regenerated reactor 12, drop into quantitative sodium-chlor then in proportion.The regenerated liquid for preparing can be used for the regeneration to 4A molecular sieve 5: at first open the valve on the pump 10B pipeline, ejector priming 10B injects regenerated liquid in needs regenerated 4A molecular sieve 5, the termination of pumping after 15 minutes that circulates is soaked and is finished regenerative process after 4A molecular sieve 5 reaches 12 hours.At every turn to all detecting calcium ions and magnesium ions content in the regenerated reactor 12 after 5 regeneration of 4A molecular sieve, drop into yellow soda ash then in proportion, can generate calcium carbonate and magnesium carbonate precipitation in the regenerated reactor 12 this moment, then to regenerated liquid processings that remove the gred: ejector priming 13C opens corresponding valve at this moment, regenerated liquid will flow to centrifuge separator 1, and the regenerated liquid after the solid-liquid separation slagging-off flows back to regenerated reactor 12 and utilizes once more.
By check, the contained high-valence cationic that influences prepared polymer of the water after this sewage treatment unit is handled is removed more than 95%; Water after processing preparation 1000ppm molecular weight be the viscosity of 1,600 ten thousand polymers soln greater than 40mPas, the viscosity of 2,500 ten thousand polymers soln can satisfy fully and join poly-viscosity criterion 40mPas requirement greater than 50mPas; After 4A molecular sieve media regeneration is handled 50 times, the water of handling out with this device still can reach the requirement of prepared polymer water, the soltion viscosity of 1,600 ten thousand, 2,500 ten thousand polymer formulation 1000ppm reaches 40mPas respectively and more than the 50mPas, and do not produce secondary pollutant, and complete assembly adopts sledge-borne type, equipment takes up an area of urinates in moving, with low cost.
