Current status and research progress of laboratory wastewater treatment

Abstract

In recent years, with the deepening development of China’s science and technology strategy, a large number of scientifi c
research institutes and laboratories are springing up like bamboo shoots after the rain, which play an important role in the development
and innovation of our science and technology. At the same time, the laboratory also produced some laboratory wastewater in the research
process. As there is no fi xed discharge cycle for these laboratory wastewater, the amount of discharge can not be accurately calculated, and
the wastewater composition is complex and the concentration is high, so it is diffi cult to treat. After investigation, it was found that some
laboratories will discharge untreated experimental wastewater directly into the sewer, which greatly increases the diffi culty and load of urban
sewage treatment, and causes great damage to the ecological environment. Therefore, it is necessary to treat the laboratory wastewater, so as
to better practice the sustainable development and the environmental protection policy of our country. In this paper, the present situation of
laboratory wastewater treatment was briefl y analyzed in the latest, hoping to provide some valuable reference for readers.
