The acid-base neutralization integrated machine in laboratory wastewater treatment equipment is a specialized device used to treat laboratory wastewater. Its core function is to reduce the acidity of the wastewater through acid-base neutralization reaction, so as to meet the national discharge standards. The following is a detailed introduction about the device:

1、 Equipment Overview

nameCenter for Disease Control and Prevention Laboratory Wastewater Treatment Equipment Acid Base Neutralization Integrated Machine

Main functionsTreating laboratory wastewater through acid-base neutralization reaction, reducing the acidity of wastewater, removing harmful substances, and ensuring that wastewater discharge meets standards.

2、 Working principle

The working principle of this device is based on acid-base neutralization reaction. When acidic and alkaline wastewater enter the reaction tank, they undergo neutralization reactions, generating salts and water. During this process, the pH of the wastewater is adjusted to a suitable range, and the large amount of heat generated also helps to lower the temperature of the wastewater. The wastewater after the reaction further enters the sedimentation tank, where suspended solids and heavy metal ions will precipitate to form sludge and be stored in the sludge tank.

3、 Equipment features

1. High degree of automationThe control system used can automatically control the operation of the equipment, reducing manual operation costs and errors.

2. High processing efficiencyCan quickly process large amounts of acidic or alkaline wastewater and meet national discharge standards, improving treatment efficiency.

3. compact footprintThe device has a compact structure and occupies a small area, making it suitable for use in places with limited space.

4. Low operating costsAdopting efficient acid-base neutralization reactions to reduce the use of chemicals and the cost of wastewater treatment.

5. easy maintenanceThe device has a simple structure, easy maintenance, and reduces the cost of equipment repair and replacement.

4、 Scope of application

This device is suitable for the treatment of various types of wastewater generated in the laboratory of the Center for Disease Control and Prevention, including inorganic substances (such as acid-base pH value, halide ions, etc.), organic substances, and biological wastewater. It can effectively remove pollutants such as COD, BOD, SS, chromaticity, heavy metals, bacteria and viruses from wastewater, ensuring that wastewater discharge meets relevant national standards.

5、 Technical parameters

According to different models and specifications of equipment, their technical parameters may vary. But generally speaking, the processing capacity of this device can reach hundreds to thousands of liters per day, with an operating power between 0.3-10KW and a power input typically of AC220V. In addition, the equipment also has PLC touch control, automatic protection and other functions to ensure the stability and safety of equipment operation.

6、 Precautions for use

1. Before using the equipment, carefully read the equipment manual to understand the operating methods and precautions of the equipment.

2. Regularly maintain and upkeep the equipment to ensure its normal operation and extend its service life.

3. Pay attention to the treatment capacity and speed of laboratory wastewater to avoid excessive or slow treatment capacity that may affect the treatment efficiency of equipment.

4. Comply with national and local environmental regulations to ensure that wastewater discharge meets relevant standards.

In summary, the acid-base neutralization integrated machine in the laboratory wastewater treatment equipment of the Center for Disease Control and Prevention is an efficient, energy-saving, and environmentally friendly wastewater treatment equipment, which is of great significance for protecting the environment and ensuring the smooth progress of laboratory work.

Characteristics and hazards of wastewater from physical and chemical laboratories

The wastewater from physical and chemical laboratories usually contains various acids, bases, salts, heavy metal ions, organic compounds, and other components. If these substances are discharged into the natural world, they will have an impact on water quality, soil, atmosphere, etc., and in severe cases, they can also cause ecological damage and health risks.

For this purpose, various professional sewage treatment equipment have been developed based on the characteristics of wastewater in physical and chemical laboratories, mainly including the following categories:

1. Physical processing equipment: including sedimentation tanks, fluidized beds, filters, MBR membranes, reverse osmosis membranes, etc. These devices can effectively remove suspended solids, particulate matter, and microorganisms from water, achieving preliminary treatment effects.

2. Biochemical treatment equipment: mainly includes activated sludge process, biological contact oxidation process, biofilm process, etc. These devices are capable of treating organic pollutants such as chemical oxides and organic compounds in water, degrading them into compounds such as carbon dioxide and water, achieving the effect of secondary treatment.

3. Physical chemical combined treatment equipment: It combines physical treatment and biochemical treatment, and through the synergistic effect of physical and chemical reactions, it can avoid the disadvantages of a single treatment technology and improve treatment efficiency.
