1、 Introduction to Laboratory Wastewater Treatment

Research is an essential course in university, and in chemistry experiments, many laboratory wastewater is discharged directly into the sewer due to its small volume, which is irresponsible to the environment. Chemical laboratory wastewater, due to its complex composition and high levels of toxic substances, can cause significant pollution to water resources and disrupt ecological balance if left untreated.

Due to the uncertainty, variability, and complexity of the experimental wastewater volume, we can collect a certain amount before processing it. The reagents and drugs used in chemical laboratories range from nearly a hundred to thousands, some of which can persist in the environment for a long time and are difficult to degrade; Some of them accumulate through the food chain and enter the human body, causing toxic effects; Some even cause secondary pollution during the degradation process. The main components of laboratory wastewater include chromium containing wastewater, cyanide containing wastewater, silver containing wastewater, phosphorus containing wastewater, aromatic nitration wastewater, amine containing organic wastewater, high concentration organic wastewater, etc. Among so many components, it is impossible to classify them all into a single category for treatment. Therefore, treating wastewater often requires a combination of several methods and a comprehensive approach to achieve better treatment results.

2、 Laboratory wastewater treatment process

There are many wastewater treatment methods at home and abroad that can treat laboratory wastewater, such as coagulation sedimentation, semi permeable membrane, reverse osmosis, etc. In practical applications, we should start from the aspects of economy, safety, and treatment effect according to the actual situation, and obtain the maximum environmental benefits with the least investment. The construction of laboratory wastewater comprehensive treatment projects aims to protect the environment, water resources, and maintain sustainable development.

After years of research and engineering practice in laboratory wastewater treatment, our company has mastered an effective treatment process. It can first undergo hydrolysis and acidification treatment, and then rely on anaerobic microorganisms for long-term biochemical reactions to break the long chains of large molecules into smaller molecular weight organic matter. After sufficient aeration, aerobic microorganisms can degrade it to the specified concentration. To ensure that the effluent meets the discharge standards. Treatment process: Experimental building wastewater → Grid → Regulating tank → Acidizing tank → Contact oxidation tank → Secondary sedimentation tank → Disinfection tank → Standard discharge.

The acidification tank does not require the consumption of other energy and is an energy-saving process. Hydrolysis and acidification can destroy the molecular structure of difficult to decompose substances, and have a degrading effect on organic compounds that are difficult to degrade with aerobic treatment. The oxygen supply in the aerobic tank adopts blast aeration and the push flow biofilm method. The pollutants in the wastewater are continuously adsorbed and degraded by aerobic microorganisms attached to the packing in the tank. The effluent from the secondary sedimentation tank must undergo chlorination treatment in the disinfection tank before it can be discharged in compliance with standards.

In actual school laboratory wastewater treatment, due to the small amount, small-scale treatment tanks can be built. Firstly, the waste liquid is collected and stored in the tank. Then, sufficient sludge is added and acidified with an appropriate amount of sulfuric acid. Due to the ample treatment time, it can be fully reacted after long-term storage. Therefore, in actual treatment, we can adopt a multi-stage treatment scheme instead of diluting the wastewater as in the experiment, gradually reducing the chromium concentration in the wastewater to achieve better results.

3、 Scope of application for laboratory wastewater treatment

Suitable for laboratory wastewater treatment in chemical and biological laboratories of testing institutions, chemical and biological laboratory wastewater treatment of monitoring stations, school chemistry and biological laboratory wastewater treatment, scientific research institution chemistry and biological laboratory wastewater treatment, enterprise laboratory chemistry and biological laboratory wastewater treatment, and other field rationalization laboratory wastewater treatment.
