Embodiment Construction
[0014] The present invention as Figure 1-2 As shown, it includes a hydrolytic acidifier 1, an inclined plate separator 2, a pretreatment filter 3, a gravity separator 4, a high-efficiency coalescence separator 5, an ultraviolet sterilizer 6 and an adsorption filter 7 connected in sequence;
[0015] The hydrolytic acidifier 1 is provided with a sewage inlet 10, and the adsorption filter 7 is provided with a clear water outlet 70;
[0016] The pretreatment filter 3 (the prefilter can effectively filter fine suspended particles (10 μm) in water, protect the high-efficiency coalescence separator, and prolong its service life) is connected to the inclined plate separator 2 through a lift pump;
[0017] The gravity separator 4 communicates with the preprocessor 3 through a lift pump. In the gravity separator 4, the characteristics of its long process are used to make the fine oil particles fully contact and gradually grow up and float up. More than 80% of the oil is collected and ...

The invention discloses an oil-containing sewage treatment system and releates to the field of environment protection. The invention provides the oil-containing sewage treatment system having a simple structure, high treatment efficiency and a small land occupation area. The oil-containing sewage treatment system orderly comprises a hydrolysis acidifier, an inclined plate separator, a pretreatment filter, a gravity separator, a high-efficiency coalescence separator, an ultraviolet ray sterilizer and an adsorption filter, and the above devices are orderly communicated. The hydrolysis acidifier is provided with a sewage inlet, the adsorption filter is provided with a clear water outlet, the pretreatment filter is communicated with the inclined plate separator by a lifting pump, and the gravity separator is communicated with the pretreatment filter by the lifting pump. The oil-containing sewage treatment system greatly improves oil-containing sewage treatment effects and treatment efficiency. The hydrolysis acidifier adopts a novel, advanced, light-weight, high-strength and large-porosity elastic filler forming a film easily as a bacterial vector so that the oil-containing sewage treatment system has the characteristics of excellent current characteristic and installation and maintenance convenience.
Description
technical field [0001] The invention relates to the field of environmental protection, in particular to the improvement of the oily sewage treatment system in the complete set of environmental protection equipment. Background technique [0002] The purpose of oily sewage treatment is to remove oil, suspended solids, additives and other unfavorable components in the water, so that the treated sewage can be discharged directly. The technologies used include more than a dozen methods such as gravity separation, coarse granulation, flotation, filtration, membrane separation and biological methods. The water quality components of oily sewage are complex and vary greatly, so the treatment process should be selected. At present, the traditional oily sewage removal process generally has defects such as complex structure, low treatment efficiency and large floor area. Contents of the invention [0003] Aiming at the above problems, the present invention provides an oily sewage tr...
