Underground restaurant waste water discharging device

Abstract

The invention relates to an underground catering waste water discharge device, which includes a tank body. The inner chamber of the tank body is separated by two partitions into a sundry interception area, an oil-water separation area, and a waste water lifting area distributed sequentially from right to left. The interception area and the bottom of the oil-water separation area, and the oil-water separation area and the bottom of the wastewater lifting area are respectively connected through water flow channels; the tank body is provided with a water inlet port connected to the debris interception area and connected to the waste water lifting area. The water outlet port and the air pipe; the upper part of the debris interception area is provided with a debris interception grille, and the bottom of the debris interception area is fixed with a micro-nano bubble generator; The bottom is provided with a one-way valve that opens toward the upper part; two lifting pumps are arranged in the waste water lifting area, and a liquid level regulator is set in the upper part of the waste water lifting area. The invention can be installed underground, is environmentally friendly and ecological, has convenient operation and maintenance, good oil-water separation effect, and low failure rate.

Description

technical field [0001] The invention relates to the technical field of wastewater discharge equipment, in particular to an underground catering wastewater discharge device. Background technique [0002] With the rapid development of the catering industry, the treatment and discharge of oily catering wastewater in shopping malls, supermarket food areas, staff canteens and other places has become increasingly prominent. Direct discharge of waste water without oil separation pretreatment will lead to poor drainage, waste water overflow, odor emission and even pipeline blockage. Although oil separation equipment has been gradually popularized, the development and application of such products are still in the initial stage of exploration. There are still defects such as low oil separation efficiency, easy clogging and strong odor, poor matching of actual working conditions, and many faults. Moreover, the oil content of the effluent cannot meet the national regulations, which wil...

Problems solved by technology

However, this method requires concrete equipment pits to be poured outdoors, which is likely to have adverse effects on the surrounding environment; at the same time, the equipment installed in the pit has a small space for operation and maintenance, and no one manages it. Frequent faults, poor oil-water separation effect, heavy odor, and effluent water cannot meet the national discharge requirements; in addition, the equipment installed in the form of an outdoor pit usually adopts the self-flow discharge water discharge method, and the effluent water is connected to the sewage inspection well. In case of heavy rain, rainwater is mixed into In the end, it is very easy to cause sewage backflow, which will eventually lead to equipment failure or even scrapping in the pit

Therefore, using this method, there are problems such as long construction period, large adverse impact on the environment, inconvenient installation, operation and maintenance, high failure rate, substandard water discharge, heavy odor, and sewage backflow.
