Embodiment Construction

[0028] The control device for maintaining the automatic operation of the SBR reactor consists of

[0029] (1) Inlet control system.

[0030] It is jointly realized by time relay T1, time relay T2 and intermediate relay M1. Realize the periodic output of the working current of the water inlet pump. The time relay T1 is used for pump stop timing, and its input terminal current is connected to the output terminal current of the intermediate relay M1. The switch terminal current of the relay is realized. The intermediate relay M1, the time relay T1 and the time relay T2 form a loop circuit, and the switch terminal current is provided by the output terminal current of the time relay T2, and the output terminal current is used as the switch terminal current of the time relay T1.

[0031] (2) Water control system.

[0032] It is composed of time relay T4, time relay T5 and intermediate relay T2. Realize the periodic output of the working current of the water outlet pump.

Abstract

The invention discloses a control device and a method for ensuring the automatic operation of a SBR reactor. The device comprises a time relay, an intermediate relay, a liquid-level controller and a circuit board, and involves a water intake control system, a water control system and a liquid-level control system. The control method comprises the following steps: water intake control, reaction control, precipitation control, drainage control and idle control. The invention can efficiently control the orderly operation of the five steps of water intake, reaction, precipitation, drainage and idling of the SBR reaction process, and the automatic control device has excellent price / performance ratio.

Description

technical field [0001] The invention relates to a control device and a method for an activated sludge reactor, more specifically to a control device and a method for the automatic operation of an SBR reactor. Background technique [0002] SBR (Sequencing Batch Reactor, referred to as SBR), SBR is an activated sludge reactor that reacts intermittently in time series, including five different reaction processes including water intake, reaction, sedimentation, drainage, and idleness. It is carried out in one reactor, and the operation status of each different reaction process can be flexibly adjusted according to the nature of the treated sewage and the effluent standard. Compared with the traditional activated sludge method, there is no secondary settling tank that occupies a large area, and there is no special Large-scale equipment such as aeration tanks and anaerobic tanks, therefore, the SBR has a compact structure and a small footprint, and can be set up as a reactor with ...
