Description
Technical field
This utility model belongs to field of sewage treatment equipment, removes the walnut shell filter of heavy metal in oil-polluted water more particularly, it relates to a kind of.
Background technology
Most oil fields all adopt water flooding recovery, and in oilfield exploitation later stage integrated water containing rate up to more than 90%, the water yield in oil well thing is much larger than oil mass. These water in gas-liquid separation, crude oil purification process with crude separation, become oil-polluted water. With the continuity of recovery time, this kind of sewage also can continue to increase, and is the main source of oilfield sewage. For saving water resource and prevent contaminated environment, it is necessary to oil-polluted water is processed, in common oily waste water treatment filter in the market, walnut shell filter with its high throughput, good treatment effect, simple to operate and occupy the very big market share.
Walnut shell filter is with walnut shell for filter medium, through the walnut shell of special handling, owing to surface area is big, and high adsorption capacity, thus clearance is high, it can remove the oil in water and float. But due in oil-polluted water possibly together with heavy metal, COD and microorganism, existing walnut shell filter cannot remove it, and reaches water quality emission request. And after walnut shell filter works long hours, when filter material surface greasy dirt reaches certain thickness, in device, pressure raises, filter capacity declines, walnut shell filter is caused damage, affecting the result of use of walnut shell filter, the greasy dirt of the bulk that hardens when backwash cannot crush the greasy dirt causing that overfall blocks when cannot get rid of flushing.
As China Patent Publication No. is: CN203558890U, publication date is: the patent documentation on April 23rd, 2014, discloses a kind of oily water filter, including tank body; Described tank body one upper lateral part is provided with water inlet, and described tank body opposite side bottom is provided with outlet; In described tank body, middle part is provided with a filtering layer, and described filtering layer is arranged over filtrate, and described filtrate composition is walnut shell;Described tank body top is provided with stirring motor, and the shaft of described stirring motor is through tank body top and gos deep in filtrate, and described shaft lower end is provided with stirrer paddle; Described tank base is provided with discharging opening and backwash outlet; Tank body above described filtering layer is provided with backwash water inlet; Described tank body top is additionally provided with relief valve and evacuation port. This utility model adopts walnut shell to be filtrate, and the stable chemical nature of filtrate, good hydrophilic property, oil resistant leaching ability is strong, and regeneration capacity is convenient and swift; The cost of filtrate is low, and backwash intensity is low, and operating cost is relatively low; The design of relief valve makes safety of the present utility model strengthen further.
And for example China Patent Publication No. is: CN204384920U, publication date is: the patent documentation on June 10th, 2015, disclose a kind of mechanical agitation type walnut shell filter, it is be provided with water-locator at tank body internal upper part, bottom is provided with integrated form captation, is provided with walnut shell filtering material layer on integrated form captation; Be placed in the agitating device at tank body top, the shaft termination of its output is flexibly connected with integrated form captation, is provided with tooth-like agitator on shaft; Being provided with flowoff gas vent on the top of tank body, the sidewall of tank body is provided with water water inlet before filter, and before filter, water water inlet connects with water-locator, and the bottom of tank body is provided with water outlet after filter. This filter, have employed rational water-locator and captation, simplifies the structure of stream oriented device, it is prevented that the subsequent techniques such as anticorrosion are caused trouble; Having selected the tooth-like agitator of end face, made walnut shell filtering material mutual rubbing collision probability when backwash increase, the conventional soft washing of air water is changed into the strong mode of washing of mechanical type, thus solving, filtrate hardens, the technical barrier of the backwashes such as knot is stained with by biological caking, oil.
Oil-polluted water can be deoiled process by above two scheme, but they deoil thorough not, and in the water after process, oil content is still higher, it is necessary to depths reason further, and they all cannot remove the heavy metal in sewage, and the water quality after process does not reach discharge standard.
