Description
Technical field
The wastewater treatment equipment that the present invention relates to refers in particular to a kind of device that is used to handle oil field waste.
Background technology
Domestic each oilfield treatments oil field waste mostly adopts oil removal (removing suspended state oil), coagulation air-float (removing emulsification attitude oil), filter, " the old three covers " technology that is aided with biochemical treatment (removing solubilised state oil and most organic), its treatment process needs big floor space, oil removal efficiency is not high, especially bad to emulsification attitude oil removal effect, the effluent quality instability, and it is the central factor of decision deoiling effect that medicament adds always, also be the lower where the shoe pinches of the long-term water quality reaching standard rate in each oil field, a series of problems of bringing have thus restricted the development in oil field.
The oil field waste salinity is high (to be Cl
-The content height), thus the specific conductivity height, satisfied the required condition of electrolysis, when adopting electric floating method to handle, need not a large amount of medicaments and regulate specific conductivity, can realize that oil removing and electrolytic sterilizing are integrated, have certain advantage during use.Patent No. ZL 02288681.8, Granted publication CN2579880Y, utility model patent, name is called " a kind of oil field waste treatment unit ", this patent is to realize that the oil removing sterilization is integrated, remove suspended substance and oil slick, paucidisperse oil but electric float method mainly lays particular emphasis on, still need use chemical agents such as adding flocculation agent or flotation agent to remove oil in water emulsion and be partly dissolved oil, just can make discharging of water outlet water quality reaching standard or reuse.
Adopt magneticsubstance to handle oil field waste, what domestic and international application research was maximum is high gradient magnetic separator, but have that device complexity, power consumption are big, magnetic kind cost height, recycling be than shortcomings such as difficulties.And directly adopt the Fe of natural magnetite particulate or synthetic
3O
4Magnetic is as the magnetic kind, to the pollutent in the water, for example bacterium or virus, turbidity, colourity, greasy dirt, heavy metal ion, dissolved organic matter, radioactive pollutant etc. have certain adsorptive power, but the removal effect to water pollutant when using separately is not good, when generally in waste water, adding the magnetic kind, need add a certain amount of coagulating agent, form the magnetic flocculation effect and reach the purpose of removing pollutent.
Summary of the invention
The present invention seeks to overcome the shortcoming of prior art, propose a kind of electric floating associating to use the device of handling oil field waste with the adsorption filtration of modification magnetic-particle.
The technical solution adopted for the present invention to solve the technical problems is:
Oil field waste enters electric floating region through intake pump, by D.C. regulated power supply control electric current and voltage size, thereby number of bubbles and size that the control electrofloatation produces, oil slick in the waste water, most of dispersed oil and small portion oil in water emulsion float with microbubble, stick to and brought to the water surface on the micro bubble, oil slick slag and greasy filth are collected by oil header and are discharged.The quantity of battery lead plate is relevant with unit scale and size of current, and the distance between the battery lead plate is 1～2cm.Waste water has improved the stability of current through greatly reduce flow velocity behind 45～60 ° flow guiding inclined plate, provides good hydraulics for oil droplet impurity, flco and colloidal fully float, and has improved the treatment effect of electric floating region.Electric floating reaction zone water outlet is passed porous plate and is upwards flowed into modification magnetic-particle adsorption filtration district, and the modification magnetic-particle is for through electric floating emulsified oil droplet and the fine impurity that can not effectively remove the good treatment effect being arranged.The modification magnetic-particle places in the brandreth frame, and particle diameter is many in 1～3mm, adsorb to be convenient to change or take out processing after saturated.Reaction zone water outlet overflow is to the catchment area, by the rising pipe discharger.Reaction zone and exhalant region water surface top are equipped with oil header, are used to collect oil slick slag and greasy filth.
The adsorption filtration of modification magnetic-particle is to make the oily(waste)water after the electric floating processing of front end upwards flow into the modification granular magnetic layer that places in the brandreth frame from the bottom, and oil and other impurity in the waste water are adsorbed.For the impure many waste water of oil-containing in enormous quantities, be easy to generate choking phenomenon, but emulsification attitude oil and fine impurity are had better processing power.It is to utilize the magneticaction of magnetic-particle and the comprehensive action of particle surface adsorptive power, reduces emulsification attitude oil and other fine impurity contained in the oily(waste)water.The particle diameter of magnetic-particle is too small, and then the flow resistance of Chan Shenging is big, easily stops up; Particle diameter is too big, and then adsorption surface area reduces, and absorption property descends, so particle diameter is many in 1～3mm.In order to strengthen the performance of this magneticsubstance, improve the lipophilicity and the hydrophobicity of magnetic-particle, generally need earlier magnetic-particle to be carried out surface treatment, with Fe
