Problems solved by technology
[0004]1. Very high oil content, very high COD, poor biodegradability, cannot undergo direct biochemical treatment;
[0005]2. The oil exists in an emulsified state, and the oil-water separation cannot be achieved through ordinary oil separation;
[0006]3. If the method of demulsification is adopted, or if there is chemical addition during the process, the thick oil cannot be recycled, and the further treatment of the thick oil becomes difficult

Embodiment 1
[0031] 1. Cutting fluid, cleaning fluid, and a small amount of lubricating oil used in the production of automobile engines are used as the raw water of this example, and the specific water quality data are shown in Table 1;
[0032]
[0033] 2. Discharge the emulsified waste water such as cutting fluid, cleaning fluid, and a small amount of lubricating oil into the regulating pool to adjust the water quantity and quality.
[0034] 3. Use a pump to lift the wastewater from the regulating tank to the inclined plate oil separator, and the surface load of the inclined plate oil separator is controlled at 1.5-2.5m 3 / m 2 ·h, the floating oil is discharged from the oil collection pipe to the oil storage tank, the sediment is discharged from the sludge discharge pipe to the filter II, and the water filtered by the filter II is returned to the regulating tank; adjust the oil collection pipe according to the actual operating conditions The high and low positions enable the slick o...

Abstract
The invention relates to a membrane method treatment process for emulsion waste water. The membrane method treatment process for the emulsion waste water mainly comprises four steps of pretreatment before the membrane, organic tubular ultrafiltration membrane treatment, inorganic tubular ultrafiltration membrane treatment and membrane bioreactor (MBR) treatment. By the process, oil, chemical oxygen demand (COD), suspended solids and the like can be effectively removed from the emulsion waste water; the water quality after treatment meets the first-level emission standard requirement of 'Integrated Wastewater Discharge Standard GB8978'; medicaments are not added in the treatment process, so the operating cost is reduced and the concentrated liquid after treatment can be recycled.
Description
technical field [0001] The invention relates to a process for treating industrial waste water, in particular to a process for treating emulsion waste water by adopting membrane integration technology. Background technique [0002] The composition of the emulsion used in the production of engines or other mechanical processing is relatively complex, and the oil content is very high, and the oil in it is in an emulsified state. Under normal conditions, it cannot be separated from water like slick oil, and the oil content remains the same even after demulsification. Higher, not up to the standard of normal biochemical treatment; At present, for the treatment of engine emulsion or other emulsions for mechanical processing, there are many low-level treatment processes, and there is a process of simple treatment and then evaporation treatment. There is a lot of energy wasted, the operating cost is high, and there is also direct biochemical treatment after oil separation and air fl...
