Abstract

The utility model relates to a sewage treatment equipment, in particularly an oil removal equipment which includes an oil removal equipment case body, a filtering screen, an air bladder generator and an oil removal device. The oil removal equipment case body is divided into a water inlet chamber, a treating chamber and a water exhaust chamber that the bottoms are communicated each other by a left and a right upper table flap, a filtering screen is set in the water inlet chamber, the treating chamber is divided into a left treating chamber and a right treating chamber that the tops are communicated each other by a down table flap, the air bladder generator is fixed on the left treating chamber bottom. The oil removal device includes a circulating reciprocating oil scraper device, an oil collecting groove and an oil exhaust pipe, the oil collecting groove is fixed on the circulating reciprocating oil scraper device end for receiving sump oil scraped by the oil scraper board. The air bladder generator generates micro-bladder for forming air flotation region, oil grease clings to the micro-bladder by surface tension and floats to surface, then is scraped to the oil collecting groove for exhausting to the case body which can increase sewage treatment effect greatly and reduce pollution of the sewage to environment.

Technical field

The utility model relates to a kind of sewage disposal device, particularly relates to a kind of oil removal equipment.

Background technology

Along with city and development of urbanization, the scale in hotel, hotel, dining room enlarges day by day, quantity is increasing, the food and drink waste water amount of Chan Shenging is also increasing thereupon, according to incompletely statistics, the food and drink waste water quantity discharged accounts for 3% of city domestic sewage quantity discharged, but content of harmful such as wherein contained BOD5 and CODcr account for 1/3 of total load, as seen, these source of pollution of food and drink waste water are the one of the main reasons that cause the peri-urban water pollution.Traditional oil trap (well) has following distinct disadvantage: oil-water separation is bad, thereby oil slick is not easy to remove and causes surrounding enviroment abominable and produce strong peculiar smell: and do not possess the removal water pollutant, and as the function of SS, BOD5 etc.Wherein CODcr is the chemical oxygen demand that adopts potassium bichromate (K2Cr207) to determine as oxygenant.BOD5 is biological oxygen demand (BOD) Biology Oxygen Demmand on the five, refers to the be degraded amount of oxygen of post consumption of organism that the microorganism in the water can degrade.

The utility model content

Technical problem to be solved in the utility model is that the existing oil trap oil-water separation of solution is bad, and oil slick is not easy to remove and causes sewage to discharge the problem of after stain surrounding enviroment.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted provides a kind of oil removal equipment, comprises the oil removal equipment box, filtering net and bubble generator.

Described oil removal equipment box is separated into intake chamber, treatment chamber and the drip chamber that the bottom interconnects by the left and right flap of going up, described intake chamber is provided with water inlet pipe, drip chamber is provided with water leg and is provided with and leads to the outer water shoot of oil removal equipment box, and the top of oil removal equipment box is provided with sealing cover; Filtering net is fixedly installed on the below of water inlet pipe in the intake chamber;

Be provided with lower flap portion in the treatment chamber, lower flap portion is divided into left treatment chamber and the right treatment chamber that the top is interconnected with treatment chamber, and described bubble generator is fixedly installed on left bottom of treatment chamber.

As improvement of the present utility model, also comprise the discharge equipment that is arranged in the treatment chamber, described discharge equipment comprises support on the inwall that is fixed on casing, by the motor-driven oil-scraping device that moves in circles, oil trap and oil exit pipe; The described oil-scraping device that moves in circles is fixedly installed on the described support, and the upper surface of the annular driving band of oil-scraping device is provided with some oil scraping plates hinged with it; Oil trap is fixedly installed on the end of the oil-scraping device that moves in circles, and is used to receive the sump oil of oil scraping plate scraping delivery; Oil exit pipe and oil sump are used to discharge sump oil to the oil removal equipment box.

Further, described oil scraping plate is two, on the uniform upper surface that is arranged on annular driving band.

The water leg top is provided with ventpipe, is used for the waste water stink is discharged; Chamber bottom is provided with blow-down pipe, is convenient to overhaul of the equipments.

The utility model, sewage from catering business enters the oil removal equipment box by water inlet pipe, the stainless steel fine screen mesh that is installed in water-in is got rid of slightly, macrobead and residue, sewage enters left treatment chamber behind flap water conservancy diversion on first, bubble generator in the treatment chamber of a left side produces micro-bubble and forms air flotation zone, because surface tension effects, grease is attached on the micro-bubble, and is floating to the water surface; Oil slick is scraped to oil trap by automatic oil-scraping device, discharges casing by oil exit pipe, and the sewage flap on second after handling through oil extraction is guided to the water leg of drip chamber, is discharged by water shoot again.So, improved wastewater treatment efficiency greatly, reduced the pollution of sewage effluent environment.
