Background
The kitchen waste treatment mainly comprises landfill, incineration, anaerobic fermentation and aerobic fermentation, and according to the current national development, the aerobic fermentation is relatively environment-friendly and is also the direction of reducing the amount of the waste in the three-quarter-turn process in recent years.
Aerobic fermentation is performed at high temperature, and fermentation is performed at normal temperature or low temperature, but in any mode, about 65-95% of kitchen waste is pretreated and fermented and then is discharged, and about half of sewage is sewage directly generated by filtering or extruding the waste in a physical mode without fermentation. The sewage is complex in components and mainly comprises biological grease, animal grease, solid suspended matters and the like. How can these sewages be discharged, which cannot be discharged directly?
In order to discharge the sewage to reach the standard to urban sewage pipe network channels, the sewage needs to be treated by a sewage isolation pool device for discharge (the project researches are that the source reduction scene is that the produced sewage is less than or equal to 50 tons/hour, and the common project is 2 tons to 30 tons/day).
The sewage isolation device is used for removing heavy suspended substance residues and separating out oil layers in water, after the treatment, water can meet the requirements of municipal sewage pipe networks, and if the sewage discharge requirement is higher, other devices can be added behind the device.
According to the technical scheme adopted in the prior art, referring to fig. 1, after solid is filtered after entering a solid treatment net 10 through a water inlet 11, oil-water mixed liquid flows into a floating oil separation area 20, the specific gravity of oil is low, so that oil floats upwards, water flows into a water drainage area 30 at a lower layer, the oil is discharged after being opened at an oil discharge valve 21, and the water flows out when reaching a water outlet, so that the oil-water separation device is mainly applied to places such as canteens.
In another technical scheme, referring to fig. 2, the water inlet enters, the vegetable residue 22 sinks, the oil layer 23 floats upwards, the oil layer 23 is kept in the floating oil separation area 20, and water flows to the water drainage area 30 and is discharged from the water outlet 31.
The working principle of the two prior technical schemes is similar, the oil-water separation pool utilizes the specific gravity difference of oil water and suspended matters, an oil layer 23, a water layer and vegetable residue 22 are separated out under the action of gravity by a natural floating separation method, and secondary pollution can not be generated without chemical treatment and the like in natural separation. In practical application, the isolation pools are cascaded, and the effect is better, wherein the isolation pools are usually in 2-4 stages.
The defects of the scheme are as follows: (1) the liquid level of the oil layer 23 cannot be known, and the cover needs to be manually opened to observe each time; if the oil layer 23 is not cleaned in time, the oil layer 23 overflows through the water outlet 31, so that the water body is polluted; (2) frequent uncapping leads to manpower resources extravagant, and the well lid is heavier, inconvenient opening, can't supervise and inform fortune dimension personnel to the administrator moreover.
