Recently, many people have been looking for laboratory acid-base waste liquid collection and treatment equipment on the Internet. This is inseparable from the increasing emphasis on laboratory waste liquid. Generally speaking, laboratory acid-base waste liquid belongs to inorganic waste liquid. Wastewater containing inorganic acid-base salts and other compounds, but not containing organic compounds, such as wastewater from sulfuric acid plants and wastewater from synthetic ammonia.

Inorganic wastewater mainly refers to wastewater mainly containing inorganic substances, and there may be some organic substances in it. Organic wastewater mainly refers to wastewater mainly containing organic substances, and of course there are inorganic substances in it.

The COd of inorganic wastewater is high or low. The reason is that COd is the amount consumed by oxidizing potassium dichromate, and potassium dichromate is very oxidizing, so as long as there is a reducing inorganic substance, cod will exist. The higher the nature of the inorganic substance, the higher the COd. There is no limit. For example, the COd of inorganic wastewater containing sulfide is as high as tens of thousands or even hundreds of thousands.

Generally, there are two treatment methods for acid-base waste liquid. 1. Use recycling methods as much as possible. Purify the waste liquid according to the specific dosage requirements of the test done in the laboratory, adjust the pH, and reuse it as much as possible. If the acid-base concentration in the waste liquid is relatively low, it can be concentrated and purified, and then recycled. 2. The method of neutralization reaction treatment can be used. The neutralization reaction is a typical reaction between acidic reagents and alkaline reagents. The waste acid and waste alkali of the laboratory exhaust gas are discharged into the sewer pipe after alkaline neutralization.

However, these laboratory acid and alkali waste liquids are always temporarily stored in a container, which is usually a waste liquid bucket, but this type of waste liquid bucket cannot prevent the volatilization of the acid and alkali waste liquid. The waste liquid volatilizes. The gas is inhaled by laboratory staff for a long time, and it will cause serious health effects over time. How to prevent the volatilization of waste liquid at the source is the most fundamental original intention of every laboratory teacher to search for laboratory acid and alkali waste liquid collection and treatment devices.

Now, the green laboratory series products launched by Beijing Aowei Instrument Co., Ltd. provide green and safe solutions for the safe sealing of laboratory solvent bottles and laboratory waste collection, protecting the laboratory environment and the health of laboratory personnel.

The funnel-type waste liquid collection device is used to collect the waste liquid during the experiment. The exhaust gas filter efficiently adsorbs harmful gases to protect the health of the experimenter. Liquid level alarm prevents liquid overflow. Various types of secondary containers prevent secondary pollution and meet regulatory requirements.

Intubation type waste liquid collection device can be used to collect waste liquid discharged from spectrometer, liquid chromatograph, mass spectrometer and pre-processing equipment in the laboratory. The exhaust gas filter can efficiently adsorb the volatilized harmful gas and protect the laboratory environment , Care for the health of experimenters. Liquid level alarm prevents liquid overflow. Various types of secondary containers prevent secondary pollution and meet regulatory requirements.

SE series solvent safety bottle caps can be used for the safe sealing of solvent bottles in liquid chromatography, automatic solid-phase extraction, pressurized solvent extraction instruments and other instruments and equipment. When the instruments and equipment are working, they can efficiently filter dust in the air to prevent solvent contamination and ensure The accuracy of the analysis results can prevent the solvent from volatilizing through the air inlet when the instrument stops working, and protect the laboratory environment from pollution.
