A kind of hotel sewage treatment system and using method

Abstract

The invention relates to the field of hotel waste management, in particular to a hotel sewage treatment system and its use method. It includes regulating tank, primary settling tank, secondary settling tank, fermentation tank, inactivation tank and recovery tank. The regulating tank is located under the sewer pipe of the hotel. The outlet gate of the regulating tank is connected with the primary settling tank. The pipes with water pumps are connected, the bottom discharge port of the primary settling tank and the secondary settling tank are connected with the fermentation tank, the outlet gate of the secondary settling tank is connected with the hotel garden water pipeline, the fermentation tank is connected with the inactivation tank, and the inactivation tank is connected with the recovery tank. The pool is connected. The treatment system of the present application, on the one hand, can treat and reuse sewage, and on the other hand, can also gradually degrade the large pieces of hotel waste into small pieces without the need for physical crushing, and finally turn them into fertilizers. For hotel green plants, the system and usage method of this application have low cost and are applicable to all types of hotels.

[0002] Sewage refers to waste water, sewage and waste liquid produced in the production process, which contains production materials, intermediate products and products lost with water, and pollutants produced in the production process. With the rapid development of the breeding industry, the types and types of sewage The number is increasing rapidly, and the pollution of water bodies is becoming more and more extensive and serious, threatening human health and safety. Therefore, for the protection of the environment, the treatment of sewage is particularly important. The sewage in hotels contains a large amount of oily impurities, especially in kitchens. Wash the used sewage during meals. Due to the variety and quantity of cooking in the hotel, especially the animal oil contained in various meats, if it flows directly into the sewer without cleaning, it is easy to cause oil accumulation and odor, especially in hot weather. In summer, it has a serious impact on the lives of nearby residents. The existing hotel sewage treatment method is relatively simple and the filtering effect is not thorough. As a result, there are still a large amount of oily substances in the treated sewage, which seriously affects the surrounding living environment.

And more than 80% of hotels will not reuse sewage and waste. This is mainly because the types of waste are complicated, and it is difficult to treat them without classification. There is no treatment method for all types of waste.
