Operation early warning system and method for decentralized micro sewage treatment device

Abstract

The invention discloses an operation early warning system and method of a dispersed micro sewage treatment device. The early warning system comprises a reaction tank where a water inlet pump and a water outlet pump are located, a liquid level signal monitoring system, a flow monitoring system, a flow control system and a programmable logic controller. The programmable logic controller is provided with a total period duration, a water inlet pump work starting time, a water inlet pump work ending time, a water outlet pump work starting time, a water outlet pump work ending time, a biochemical reaction work starting time and a biochemical reaction work ending time. The programmable logic controller compares and analyzes the collected data and achieves system early warning and switching of a system continuous flow operation mode or a sequencing batch operation mode through the time and liquid level signal monitoring system and the flow control system under the action of operation logic. The operation early warning system is simple to install and transform, convenient to operate and switch, capable of effectively adapting to the characteristic of large fluctuation of sewage quantity in decentralized areas and stable in treatment effect.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an operation early warning system and method of a dispersed micro sewage treatment device, which can be applied to the switching of the operation mode and the monitoring and early warning of the operation status of the dispersed micro sewage treatment device. Background technique [0002] The sewage in remote and scattered areas such as expressway service areas, toll stations, and resorts has the characteristics of small water volume, large fluctuations in water quality and volume, and inability to connect to local municipal pipe networks. However, in order not to damage the surrounding ecological environment, small and micro sewage treatment facilities need to be built separately to meet relevant environmental protection requirements. [0003] Most of the existing sewage treatment equipment used in scattered areas adopts a continuous flow based on anaerobic-...
