Embodiment Construction

[0017] The application examples of the device and method will be described below in conjunction with the accompanying drawings. Xining Qinghai Jieshen Food Waste Treatment Co., Ltd. implemented a 60m3 / d intermittent

[0018] The operating treatment device has a grease content of 50,000mg / l, which is pumped into a gravity oil separation tank (1m×4m), with an ascending flow rate of 4m / h, an oil skimmer speed of 10m / min, and an outlet oil concentration of 500mg / l l; the water from the gravity oil separation tank enters the micro-air flotation oil skimming tank (2m×2m×1m) through the overflow weir, the hydraulic retention time is 30min, the steam-water ratio is 100:1, and the oil concentration in the effluent is 50mg / l; micro-air flotation skimming The effluent from the oil tank enters the coarse-grained oil removal tank (horizontal pipe: 1m×1m, vertical pipe: 1m×1m), and the filling rate of modified polyacrylamide in the horizontal pipe of the coarse-grained oil removal tank i...

Abstract

Disclosed are an oil-water separation facility and a method for refuse waste-water of kitchens, which relate to the field of environment protection. The facility and method are composed of three portions which are respectively gravity oil slick, micro-airfloat oil skimming, thick granulating and the like in accordance with grease distribution shape and character of the refuse waste-water of kitchens, wherein the gravity oil removal section automatically excludes upper oil slick, emulsified oil, dispersed oil and the like float off via the micro-airfloat, thereby achieving separation of oil with smaller particles and water, after handling, oily wastewater left by the treatment of the above two sections further proceeds thick granulating process to lead micro-grease to assemble and form the grease with big particle diameter, then the grease with big particle diameter after floating upward is removed, thereby achieving being separated from water. The facility is capable of separating highly effectively the grease in sewage water, reducing organic loading of subsequent sewage water treatment, simultaneously the separated grease can be prepared into biological diesel fuels, soapstocks and the like, thereby improving resource recycling efficiency. The method has the advantages of feasible technique, cheapness and convenience, automation operation, which is not influenced by seasonal difference in temperature.

Description

technical field [0001] The invention relates to an oil-water separation device and method in the field of environmental protection, in particular to a waste water oil separation device and method in the catering industry. Background technique [0002] The rapid development of the urban catering service industry has led to a large amount of kitchen waste, which contains a large amount of sewage with high concentrations of animal and vegetable oils. This kind of oily sewage is different from hydrocarbon-containing petroleum sewage, because the composition and existence form of oil in sewage are more complicated because of high-temperature treatment and vigorous stirring and mixing. This kind of wastewater is directly discharged to the urban domestic sewage pipe network, and the grease is easy to adhere to the pipe wall, which is easy to block the pipe, and it is difficult to dredge, causing a huge burden on the urban municipal management department. When the oily wastewater i...
