Ⅰ.Summary of case

In recent years, with the rapid development of economy and the acceleration of urbanization, the catering industry, as a pillar industry in the tertiary industry, plays an important role in promoting economic growth and improving people's life. However, many environmental problems are also becoming increasingly evident. Studies have shown that in addition to vehicle exhaust and industrial exhaust, the catering industry has been one of the main sources of fine particulate PM2.5.

However, due to the large number of catering enterprises, wide distribution, intermittent emissions, lack of information and the difficulty of monitoring, it is difficult to achieve the supervision effect by relying on limited manpower. Therefore, there is an urgent need to build a monitoring and supervision system for catering waste gas, to provide targeted business services for catering enterprises, operation and maintenance companies and environmental protection authorities, so as to realize the transformation of environmental supervision from civil air defense to technical defense, improve the level of accurate environmental protection supervision, and provide an important starting point for improving regional air quality and environment.

Mantoo technology provides a food fume monitoring system to an environmental protection department in hebei province, which improves the precision level of environmental supervision, constructs a supervision system for the whole process of food and beverage enterprises, improves the effective control of the food and beverage industry fume pollution, and realizes all-weather and real-time monitoring of food and beverage enterprises. Tremendous improvements through the system online at the same time, catering enterprises environmental responsibility main body consciousness, difficulty of catering enterprises violation and increase cost, reduce environmental violation number, make the catering enterprises lampblack purification equipment utilization rate, less soot emissions, reduce air pollution and improve the ecological environment quality.

Ⅵ.The customer evaluation

The online monitoring system realizes the qualitative and quantitative supervision of the lampblack emission of catering enterprises through the real-time collection, transmission and storage of lampblack data. Through the system 24 hours uninterrupted monitoring of food and beverage enterprises soot purification, timely find abnormal conditions, for our environmental protection department flexible implementation method to provide great convenience. After the system was put on line, the lampblack nuisance problem was improved, the amount of complaints significantly reduced, and the normal utilization rate of the lampblack purifier in catering enterprises was significantly increased, basically achieving the same starting time as the business time. At present, the local public shows high satisfaction with the treatment of catering pollution.
