Multifunctional integrated sewage treatment device and method thereof

Abstract

The invention relates to the technical field of water treatment equipment, and particularly relates to a multifunctional integrated sewage treatment device which sequentially comprises a control cabinet, an anoxic zone, an aerobic zone, an anaerobic zone, an anaerobic gas stripping reflux tube, a membrane treatment device, a precipitation zone and a precipitation gas stripping reflux pipe, whereinthe anaerobic gas stripping reflux tube enters the anoxic zone from the anaerobic zone, the membrane treatment device is arranged in the aerobic zone, the precipitation zone is connected to the aerobic zone, and the precipitation gas stripping reflux pipe enters the anoxic zone from the sedimentation zone. The invention further discloses a multifunctional integrated sewage treatment method, and the precipitation and membrane treatment can be selected according to different water levels. According to the multifunctional integrated sewage treatment device and the multifunctional integrated sewage treatment method, an intelligent process switching system and a processing technology are adopted aiming at the characteristics that the fluctuation of the water quality and the water quantity of the town domestic sewage is large and the like, the automatic switching of the process is realized, the stable operation of the equipment is ensured, and the standard effect of the water quality is ensured while the stable operation of the equipment is ensured.

Description

technical field [0001] The invention relates to the technical field of water treatment equipment, in particular to a multifunctional integrated sewage treatment equipment and method. Background technique [0002] Water pollution has become a difficult point in the comprehensive management of the township environment and the focus of attention of the general public. Due to the lack of necessary sewage collection and treatment facilities, domestic sewage and industrial wastewater are discharged into rural drinking and irrigation water bodies together, making the water environment pollution in most towns and towns increasingly serious, deteriorating the environment, and affecting social stability. Therefore, it is imperative to speed up the construction of township sewage treatment. However, due to the characteristics of small water volume, large initial investment in pipe network, difficult collection, and uneven water supply, township sewage will inevitably cause waste of ma...

Problems solved by technology

[0003] The fluctuations in the incoming water volume of village and town sewage are different from traditional municipal sewage. The actual situation is greatly affected by the region, living habits, economic development, etc. The traditional adjustment tank cannot meet the adjustment needs at all. Under the intelligent operation is extremely important

At present, most of the products on the market only have a single process and operating conditions, such as an air-lifting integrated treatment device mentioned in the invention patent of application number 201410432163.7 and the integrated sewage treatment provided by the utility model patent of application number CN201520849413.7 Equipment, none of which mentioned how to deal with the fluctuation of water quality and quantity
