Lianyungang has a recycling slops enterprise, which began to install an oil water separator in large and medium-sized hotel, units dining room and other catering companies for free. They will isolate the oil, water, residue from the slops, which will be unified purchased by the responsible enterprise to chemical enterprise for refining biodiesel. At present, Lianyungang has more than 200 large and medium-sized caterings' kitchen installed the oil water splitter.
As is known to all, swill-cooked dirty oil mainly comes from the hotel garbage and hogwash. So, to control swill-cooked dirty oilfrom the source , we should control the garbage and hogwash. And this, no doubt, is a difficult task. Though the hotel hogwash can be unify recovered, the garbage and slops flowed into the sewer were without management. And many outlaws salvage swill-cooked dirty oil from the sewer. Imagine, if before the garbage and slops flow into the sewer, we can isolate the grease, then outlaws will lost the chance.
In fact, oil water separator of abandoned slops' main function is to separated the grease, garbage and slops. This equipment use high-pressure aeration method to swill-cooked dirty oil with plasma reactive oxygen species. Active oxygen has the role of oil decomposition, which enable hogwash oil happen "fission", forming tartaric acid, formic acid, methanol and hydrophilic degradants, let the grease of hogwash oil completely disappear. In addition, active oxygen can remove hogwash oil's bacteria and stench, sharply improve oil pool environment. Under the action of the separator, swill-cooked dirty oil become "water", and is discharged directly to the sewer. The environmental protection supervision and inspection station determination, the invention 24 hour grease degradation rate can reach 99%.
So, garbage and slops get into the oil water separator, through twice filtering. The first time filter out scraps, the second time filter out grease. Eventually flow into the sewer is oil and water without scraps. Thus, outlaws can not have "grease" in the sewer. As for the isolated grease, will be unified recovery by the enterprise, end to take to refine biodiesel. In fact, the oil water separator of abandoned slops not only can increase the enterprise economic benefit of oil recovery, also can bring convenience for the enterprise. According to a catering business chief says, since half a month ago they installed the oil water separator, their sewer has not stuck, dining room also become more clean. The application of the oil water separator of abandoned slops can bring a win-win of oil recovery enterprise and catering enterprises.
If the catering enterprises all over the country can install oil water separator of abandoned slops, then hogwash oil will be greatly reduced. As a effective tool, oil water separator of abandoned slops is worth promoting. Experts point out that, at present the comprehensive utilization costs of hogwash oil are too high, which lead to the legal channel hogwash oil recovery can't complete with swill-cooked dirty oil. In the present conditions, the hogwash oil transform into biodiesel actually is losing money. Because of this, the enterprise lack of legal recycling hogwash oil's enthusiasm, which give the chance for the "hogwash oil on table". Experts consider that we should eliminate swill-cooked dirty oilas from the source, safeguard the people's food security.
