Description
Technical field
The present invention relates to a kind of waste disposal plant, particularly the treatment unit of scrap metal cutting fluid.
Background technology
In the contemporary metal course of processing, metal working fluid a kind ofly improves machining effect and the industrial liquid used, and metal working fluid possesses the functions such as good cooling, lubrication, antirust, anticorrosion, cleaning and is widely used.When use procedure, there is decomposition in various degree and go bad in metal working fluid, causes performance to reduce, therefore will regularly replace new metal working fluid.
Along with developing rapidly of industry, the quantity discharged of this oily(waste)water grows with each passing day.Scrap metal cutting fluid is except having the harm of general oily(waste)water, due to the effect of tensio-active agent, machinery oil is highly dispersed in water, animals and plants, hydrobiont more easily absorb, and tensio-active agent itself is also harmful to biology, some water-fast toxic substances also can be made to be dissolved, need to process and just can be discharged after reaching the wastewater treatment standard of local code.Current China oily(waste)water serious to the high density of discharging in mechanical workout, emulsification is not still processed well.Mainly due to the raising along with technology, the stability of emulsion is more and more higher, more and more difficult breakdown of emulsion.
Summary of the invention
The object of the invention is the treatment unit that the scrap metal cutting fluid that a kind of oily water separation degree is high, demulsification is good is provided to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, the treatment unit of the scrap metal cutting fluid designed by the present invention, comprise oil removal district, described oil removal district comprise connect successively unload oil sump, former water pot and oil trap, reserve is connected with in the upper end of oil trap, lower end is connected with ultrafiltration district, described reserve comprises oily concentration basin and oil storage pond, described ultrafiltration district comprises Buffer Pool and ultra filtration unit, described ultra filtration unit is made up of the circulatory pool connected successively and ultra-filtration equipment, circulatory pool is connected with water tank by water pipe head and the tail, and this water tank is also connected with ultra-filtration equipment simultaneously.Described unloading tiltingly on oil sump has screen.
After ultrafiltration district, be also connected with biochemical treatment district, described biochemical treatment district comprises the sewage lagoon, anaerobism intermediate pool, anaerobic UASB tank and the SBR tank that connect successively, and be connected with anaerobic effluent pond in the upper end of SBR tank, lower end is connected with granule sludge pond.The upper end of described anaerobic UASB tank is provided with chemicals dosing plant, is provided with aeration plate in described SBR tank.
In concrete use procedure, first grid process was carried out unloading in oil sump to scrap metal cutting fluid, this is because feed liquor is industrial scrap metal cutting fluid, the industry such as be mainly derived from machining, metal cleaning, metal is cold rolling, may there is the foreign matters such as glue, paint, larger solids, mud in it.Then waste liquid enters in former water pot and stores, after flow control, enter oil trap, and the waste liquid after oil trap process is divided into oil and emulsion two portions, and wherein oil enters reserve, and emulsion then enters ultrafiltration district.By oily concentration basin, oil is positioned in oil storage pond in reserve, in ultrafiltration district, emulsion first enters ultra filtration unit again by Buffer Pool, in ultra filtration unit, emulsion is successively through circulatory pool and ultra-filtration equipment, in ultra-filtration equipment, breakdown of emulsion process is carried out to emulsion, partially liq simultaneously in circulatory pool and ultra-filtration equipment carries out circular treatment after water tank, then biochemical treatment district is entered from ultra filtration unit sewage out, sewage passes through sewage lagoon successively, anaerobism intermediate pool, anaerobic UASB tank and SBR tank, the upper end water outlet of last SBR tank is stored in anaerobic effluent pond waits for that next step processes, mud is then transported to granule sludge pond by the lower end of SBR tank.
In order to improve the effect of ultrafiltration better, the Buffer Pool in described ultrafiltration district is connected with two ultra filtration unit.
The treatment unit of the scrap metal cutting fluid that the present invention obtains, its technique effect is by arranging oil removal district, ultrafiltration district, reserve and biochemical treatment district, profit in scrap metal cutting fluid is separated well, wherein in ultra filtration unit to the circulation breakdown of emulsion of emulsion, then improve the process intensity for emulsion.
