Abstract

The invention discloses a water level controller used for industrial sewage treatment. The controller includes a first relay circuit, a voltage reduction module, a second relay circuit, a first rectifier module, a second rectifier module, a detection electrode A, a detection electrode B and a detection electrode C; commercial power voltage is connected to the first relay circuit and the voltage reduction module; the voltage reduction module is connected to the first rectifier module and the second rectifier module; and the first rectifier module is connected to the detection electrode A, the detection electrode B, the detection electrode C and the second relay circuit. Through the combination of triodes and relays, the automatic controlling on water levels can be realized; and the increasing of a manual control device in a circuit, controlling can be performed on water inlet operation at any time during the inletting of water, and intelligence and manual combined double control effectscan be achieved.

Description

technical field [0001] The invention relates to a controller, in particular to a water level controller for industrial sewage treatment. Background technique [0002] There are a large number of refractory organic pollutants in industrial wastewater (such as chemical industry, pharmaceuticals, printing and dyeing, etc.). After traditional biochemical treatment, the refractory organic pollutants still remain in the biochemical tail water, resulting in the industrial wastewater biochemical tail water not meeting the discharge standards. , At the same time, the ecotoxicity is high, causing serious harm to the water environment. Therefore, effective advanced treatment of industrial wastewater is a common and key issue faced by industrial wastewater treatment. [0003] Industrial wastewater needs to pay attention to quantitative treatment in the treatment project, otherwise the treatment effect will be seriously affected if the one-time treatment volume is too large, so the syne...
