Laboratory waste water processing system

Abstract

The invention provides a laboratory waste water processing system capable of realizing effective and complete laboratory waste water processing. The laboratory waste water processing system comprises a preprocessing unit; an acidity and alkalinity adjusting unit communicated with a preprocessing unit; a concentrated reaction unit communicated with the acidity and alkalinity adjusting unit; a precipitation separation unit communicated with the concentrated reaction unit; a deep purification unit communicated with the precipitation separation unit; a main control unit connected with the preprocessing unit, the acidity and alkalinity adjusting unit, the concentrated reaction unit, and the precipitation separation unit via double-way connection. The laboratory waste water processing system is capable of realizing independent processing of different matters, processing is more complete, processing is performed under full-sealing conditions, contacting with the environment is not caused in processing processes or after processing, and influences on the environment are avoided.

Description

technical field [0001] The invention relates to the field of laboratory wastewater treatment, in particular to a laboratory wastewater treatment system. Background technique [0002] The generation of laboratory wastewater mainly comes from chemical experiments and scientific research experiments in colleges and universities. The uncertainty, variability and complexity of the amount of experimental wastewater are its own characteristics. It is divided into infinite wastewater and organic wastewater. Inorganic wastewater includes heavy metals and , metal complexes and inorganic substances, etc. Organic wastewater includes organic solvents, organic acids, benzene, phenols, organic phosphides, petroleum and grease, etc.; [0003] If the above-mentioned substances are directly discharged, they will cause serious impact on the environment, but there is no thorough method for decomposition or reaction in the prior art, resulting in the laboratory wastewater after treatment also co...
