Abstract

The invention discloses a full-automatic lime liquid preparing system and method for deep treatment of dyeing wastewater. The system comprises a liquid preparing tank, a water inlet pipe, a water inlet valve and a material scattering tank arranged above the liquid preparing tank. The system further comprises a liquid level sensor and a control module, wherein the liquid level sensor is used for collecting a liquid level height signal of the liquid preparing tank and transmitting the signal to the control module, and the control module is used for receiving the liquid level height signal collected by the liquid level sensor and controls the water inlet valve and a discharging valve of the material scattering tank to act according to the signal. The full-automatic lime liquid preparing system and method for deep treatment of dyeing wastewater aim at solving the problem that in the prior art, lime liquid in a wastewater station needs to be manually prepared, and thus the purpose of preparing the lime liquid in a full-automatic mode is achieved.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a fully automatic lime solution system and method for advanced treatment of printing and dyeing sewage. Background technique [0002] Sewage advanced treatment refers to the further water treatment process in which urban sewage or industrial wastewater is treated as a water resource for production or life in order to meet a certain reuse water standard after primary and secondary treatment. For raw water quality and treated water quality requirements of sewage, tertiary treatment or multi-level treatment process can be further adopted. It is often used to remove trace COD and BOD organic pollutants, SS, nitrogen and phosphorus high-concentration nutrients and salts in water. The methods of advanced sewage treatment include: flocculation sedimentation method, sand filtration method, activated carbon method, ozone oxidation method, membrane separation method, ion exchange method, ...
