With the development of the economy and technological progress, research experiments conducted by various research institutions and universities have become increasingly in-depth and extensive, accompanied by a continuous increase in laboratory wastewater discharge. This type of sewage has significant complexity characteristics: the water quality is complex, containing not only organic substances such as detergents and commonly used solvents, but also a large amount of acidic and alkaline substances, toxic and harmful organic substances, and heavy metals; The emission pattern is disordered, not only is the emission cycle not fixed, but there is also no clear pattern to follow for the amount of water.
Although the discharge of laboratory wastewater is relatively small, direct discharge without effective treatment can cause serious pollution to the environment. Research has found that many research laboratories currently only perform simple treatment on the wastewater generated, or even discharge it directly. This situation urgently needs to be improved. Therefore, further strengthening laboratory management, researching and promoting comprehensive treatment methods for laboratory wastewater, and developing treatment equipment with good treatment effects, advanced technology, and low investment has become an urgent and important issue.
There are various types of laboratory wastewater, which can be divided into three categories: inorganic, organic, and biological wastewater. Among them, inorganic wastewater contains heavy metal ions, acidic and alkaline substances (involving different pH values), halogen ions, and other non-metallic ions; Organic wastewater includes organic solvents, ammonia nitrogen, toluene, phenol, organophosphorus pesticides, etc; Biological wastewater contains harmful biological components such as viruses, chlamydia, mycoplasma, spirochetes, fungi, Brucella, anthrax, etc.
In response to the treatment needs of various laboratory wastewater, laboratory comprehensive wastewater treatment equipment has emerged, which has a wide range of applications and can be adapted to various testing and monitoring institutions such as PCR laboratories, disease control centers, food and drug supervision bureaus, and quality supervision bureaus; High schools, universities and other educational research institutions; Various organic, inorganic, chemical, and biological laboratories in related fields such as agricultural product testing centers, pharmaceutical enterprises, biotechnology enterprises, oil fields, and geological exploration provide strong support for laboratory wastewater treatment in different scenarios.
