Intelligent treatment system and process for laboratory wastewater

Abstract

The invention relates to the field of wastewater treatment, in particular to an intelligent treatment system and process for laboratory wastewater. The intelligent treatment system comprises a feedingunit used for feeding the wastewater, a neutralizing unit connected to the feeding unit through a first pipe and used for neutralizing the wastewater, a precipitating unit connected to the neutralizing unit through a second pipe and used for precipitating metal ions in the wastewater, a microbial treatment unit connected to the precipitating unit through a third pipe and used for decomposing organic matter in the wastewater as well as a control unit electrically connected to the feeding unit, the neutralizing unit, the precipitating unit and the microbial treatment unit and used for performing controlling, wherein the first pipe, the second pipe and the third pipe are all vertically circuitous S-pipes. The intelligent treatment system and process for the laboratory wastewater are high inautomation degree and treatment efficiency and good in treatment effect, and facilitate energy saving and environmental protection.

Description

technical field [0001] The invention relates to the field of waste water treatment, in particular to a laboratory waste water intelligent treatment system and treatment process. Background technique [0002] With the expansion of enrollment in colleges and universities, the surge in the number of students and the development of the economy, and the progress of scientific research, the wastewater in chemical laboratories is increasing day by day. Because the quality of laboratory wastewater is extremely complex and difficult to predict, the discharge cycle is uncertain, and the amount of wastewater is also irregular. The comprehensive treatment and recycling of wastewater is a worldwide problem. [0003] Wastewater discharged from chemical laboratories is divided into two categories. One is hazardous waste liquid with high concentration. This kind of waste liquid is highly harmful. It is generally collected separately and then handed over to a unit with processing qualificati...

[0003] Wastewater discharged from chemical laboratories is divided into two categories. One is hazardous waste liquid with high concentration. This kind of waste liquid is highly harmful. It is generally collected separately and then handed over to a unit with processing qualifications for treatment; while the other is Such waste liquids are produced in daily experiments, as well as the comprehensive waste liquids of acids, alkalis, heavy metals, and organic substances produced by cleaning experimental equipment and glassware.
