Description
Technical field
The utility model belongs to field of waste water treatment, particularly relates to a kind of oily(waste)water tiny flocculation contact percolation built-up type advanced treatment apparatus.
Background technology
Oily(waste)water is a kind of common trade effluent had a large capacity and a wide range, exploitation and processing transport, electromechanics and the industry such as mechanical workout, petrochemical complex of oil discharge a large amount of oily(waste)waters every day, the safety of water surrounding in serious harm, and after oil trap process, oily content, COD, suspended substance and other indexs are still higher, the requirement of reuse can not be met and be discharged, both having polluted environment, caused again the waste of water resources.
In oily(waste)water, the particle diameter of oil slick, solid attaching oil is comparatively large, is easily separated from waste water, can substantially be removed after oil trap (or settling tank) process; Dispersed oil and oil in water emulsion dispersity and stability higher, the conventional technique such as oil removal, air supporting is difficult to them to remove, and thus also needs advanced treatment; The general content of solubilised state oil is lower, but is not easily removed, and it first must to be converted into after insolubles row relax again.
Be that oil slick is separated with water in the primary treatment of oily(waste)water, then adopt second-stage treatment technology or post-processing technology change and are separated oil in water emulsion.Emulsification oil handling more complicated, need to carry out second-stage treatment or aftertreatment after elementary gravity separation, conventional treatment process has chemical demulsification method, By Bubble-floating Method, electrolytic process, biologic treating technique, membrane separation process, coalescence, filtration method, absorption method.
At present, the process of oily(waste)water generally adopts pond, the equipment field process of " old three covers ", i.e. oil trap, then air supporting (precipitation) pond, arrive biochemical aeration tank again, medicament wherein used is almost polymerize aluminum chloride entirely, and the flocculation structure formed due to the hydrolysis of this medicament is loose, and scum silica frost amount is large and density is little, water ratio is high, settleability and dehydration property inequality, bring very large difficulty often to follow-up sludge treatment, and inevitably cause secondary pollution.Due to normal containing inhibiter, sterilant etc. in oily(waste)water, so make the effect of the biochemical cell processing in this flow process and bad.Oil in water emulsion in oily(waste)water is under the effect of tensio-active agent, very stable, is not easily destroyed, and is difficult to process.One of traditional treatment process adds that surfactivity is higher in containing the waste water of oil in water emulsion but molecular chain is shorter or molecule has the another kind of tensio-active agent of side chain to carry out breakdown of emulsion, but the adding and new pollution can be caused of tensio-active agent.Another kind of traditional method under the effect of high tension electrostatic field, makes oil droplet to electrode movement and discharges, and reach separation, but this method is unwell to large-scale application at electrode place coalescence.
Utility model content
The purpose of this utility model is to provide a kind of simple to operate, reduced investment, reliable, reasonable effective oily(waste)water tiny flocculation contact percolation built-up type advanced treatment apparatus.
For solving the problem, technical solutions of the utility model are as follows: a kind of oily(waste)water tiny flocculation contact percolation built-up type advanced treatment apparatus, comprise oil trap outlet canal, water collecting basin, intake pump, strainer, oil trap outlet canal side is provided with the first water inlet pipe, submersible sewage pump is provided with in oil trap outlet canal, submersible sewage pump is connected with the side of water collecting basin by the first rising pipe, and the opposite side of water collecting basin is connected with intake pump by the second water inlet pipe; It also comprises backwash pump, and described strainer also connects clean water basin and air compressor respectively, and described strainer bottom is provided with the 3rd rising pipe, and the 3rd rising pipe end passes into clean water basin; One end of backwash pump (43) connects the 4th rising pipe, back flushing water inlet pipe, the second pipe connecting, and communicates with the bottom of strainer, and the other end of backwash pump is connected with clean water basin by the 4th water inlet pipe; Air compressor is connected with filter bottom by compressed air pipe.
Large for the oily(waste)water water yield, difficult degradation, the characteristics such as contaminative is strong, a kind of new and effective oily wastewater treatment method need be researched and developed, as the unit operation after oil trap or mixed precipitation pond, thus improve level and the effect of oiliness sewage treatment, to reach the object of advanced treatment and reuse.This device is mainly for the dispersed oil in oily(waste)water and oil in water emulsion, based on micro flocculating filter and contact percolation to the good result of oily(waste)water advanced treatment, creatively the two combined, appropriateness increases the yardstick of pollutent disperse phase on the one hand, is conducive to pollutent and is retained by filter bed; On the other hand can effectively reduce the electrical of filter material surface, be conducive to filtrate making full use of the absorption of pollutent and filter bed deep layer filtrate loading capacity, given full play to both respective advantages.Effectively De-emulsification flocculent and adsorption coprecipitation can remove oil in water emulsion and dispersed oil, and flocculation agent is to water body toxicological harmless effect.
The utility model adopts the homogeneous ceramsite sand filtrate that Zeta potential is lower, and the stable cycle is long, and water production rate is high, and work loading capacity is large, effectively improves the effect of oily(waste)water contact percolation advanced treatment.
The utility model adopts air water to combine recoil-water recoil advance and reliability engineering, and is aided with strainer head, filter bed can be made not stratified, rinse evenly, unsuitable deposition ball, filtrate rate of loss is low, and it is little to wash water consumption rate, saves tolerance, simple to operate, cause filter bed holomorphosis, recover its loading capacity.
The utility model water collecting basin is without mixing stirring device, the tiny flocculation occurred is that what to be caused by pedesis is incorgruous flocculation, namely saves power consumption, adds that flocculant formula used is with low cost, the cost of water treatment of this technique is caused to be 0.58 yuan/ton, far below applicable industry water price lattice.
To sum up, oily(waste)water tiny flocculation contact percolation built-up type advanced treatment apparatus of the present utility model is simple, operation investment cost is low, convenient operation and management, effluent quality reaches national grade one discharge standard, and water outlet irreducible oil concentration reaches below 12mg/L, COD clearance reaches more than 49%, turbidity removal rate reaches more than 93%, significantly improves level and the effect of oiliness sewage treatment, reaches the object of advanced treatment and reuse.
