Oil-water separation monitoring and controlling system

Abstract

The invention relates to an oil-water separation monitoring and controlling system, which aims to provide the oil-water separation monitoring system with a high automatic degree and monitoring and controlling integration. The oil-water separation monitoring and controlling system comprises a handheld terminal, an upper computer and a plurality of oil-water separators, wherein a first solenoid valve, a second solenoid valve and a third solenoid valve on the oil-water separator of an oil-water discharging point are controlled to be simultaneously switched on through the handheld terminal; after a period of time, the first solenoid valve, the second solenoid valve and the third solenoid valve are controlled to be simultaneously switched off; oil and water discharged in the time period are separated into food residues, waste water and grease by the oil-water separator, and then the food residues, the waste water and the grease are respectively collected on the top of a second clapboard, a sewage collection bucket and a grease collection bucket; a first mass sensor, a second mass sensor and a third mass sensor are respectively used for detecting the masses of the food residues, the waste water and the grease, and a detection signal is transmitted to the upper computer through the handheld terminal; the upper computer can be used for calculating the contents of the food residues and the grease in the oil and water according to the mass ratio of the food residues, the waste water to the grease.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an oil-water separation monitoring system. Background technique [0002] The oil-water separator, especially the oil-water separator for catering, is used to treat the untreated oil-water discharged by the catering industry, so that it can be discharged into the urban sewer or directly into other places after it meets the discharge standards and specifications stipulated by the state. Water body. Otherwise, the residual grease in the oil and water is easy to condense on the inner wall of the pipeline, which will block the urban pipeline network in the long run, and have a serious impact on the ecological environment and people's daily life. The main pollutants of catering wastewater are food fiber, starch, fat, animal and vegetable oils, various condiments, detergents, proteins and other organic substances. Most of these substances exist in colloidal state, and a small part exist...

AI Technical Summary

Problems solved by technology

However, the impact force of the water flow is relatively large, the noise is large, and the hydraulic loss is high.

[0008] The existing oil-water separator has a low degree of automation and a lack of temperature control function. When processing some grease with a low freezing point or processing oil and water in a low-temperature environment, the grease on the surface of the oil and water often freezes, and the equipment cannot It works normally, and the solidified grease will stick to the inner wall and pipeline of the equipment, causing damage to the equipment

At this stage, there is no unified monitoring system for whether the discharge after oil-water separation meets the standard. Only relevant departments can conduct spot checks on the oil and water discharged from catering. It is easy for some companies to take advantage of loopholes and fail to achieve real regulation and control. serious impact on and damage to the environment
