The laboratory waste liquid and wastewater treatment system equipment is mainly used to treat biological and organic wastewater generated in university laboratories, scientific research laboratories, medical institution laboratories, chemical enterprise laboratories and other laboratories. It adopts advanced technology, features a high degree of automation, is easy and simple to operate, and has a long service life.
The product features of the laboratory organic wastewater treatment equipment are summarized:
(1) According to the characteristics of different wastewater, practical and simple sewage treatment processes should be selected to minimize the complexity of the processes to the greatest extent.
(2) According to the characteristics of different types of wastewater, the number of equipment, equipment investment and floor space have been reduced to build a one-stop wastewater treatment station for customers.

What are the common treatment methods for organic wastewater in laboratories?
I. Hydrolysis method
For esters of organic or inorganic acids, as well as some organophosphorus compounds and other substances that are prone to hydrolysis, sodium hydroxide or calcium hydroxide can be added and hydrolysis can be carried out at room temperature or under heating. After hydrolysis, if the waste liquid is non-toxic, it can be neutralized and diluted before being discharged. If it contains harmful substances, appropriate treatments such as adsorption should be carried out.
Ii Oxidation decomposition method (refer to the treatment method for organic waste liquid containing heavy metals)
The oxidation and decomposition method is applied to low-concentration organic waste liquid containing water. For the waste liquid that is prone to oxidation and decomposition, substances such as H2O2, KMnO4, NaOCl, H2SO4+HNO3, HNO3+HClO4, H2SO4+ Hclo4, and a mixture of waste chromic acid are used to oxidize and decompose it. Then, the inorganic experimental waste liquid is treated according to the above-mentioned method.
Iii. Biochemical Treatment Method
Treat it by using substances like activated sludge and blowing in air. For example, this method can be used to treat dilute solutions containing ethanol, acetic acid, animal and vegetable oils, proteins and starches, etc.
Iv. Adsorption Method
Substances that can well adsorb solvents, such as activated carbon, diatomite, bauxite, laminated fabric, polypropylene, polyester sheets, ethyl carbamate foam plastic, rice straw shavings and sawdust, are used to fully adsorb them and then incinerated together with the adsorbents.
