Factory laboratory wastewater and sewage treatment equipment

According to the survey, most laboratories discharge wastewater after simple treatment without any additional treatment. It is understood that laboratory wastewater has complex water quality, irregular discharge cycles, and irregular drainage. The pollutants in the wastewater are also complex, containing not only organic substances such as detergents, but also acids, alkalis, and toxic and harmful substances. If this type of complex wastewater containing heavy metals is not treated and discharged, it will cause great harm to human health and the surrounding environment.

The laboratory sewage treatment equipment consists of a wastewater classification and collection device, a wastewater acid-base neutralization device, and a wastewater deep treatment device BOD、SS、 Composition of pigment, heavy metal ion precipitation and separation device, etc. Multiple processing techniques and control systems were used. It is composed of physical treatment units, biological treatment units, and comprehensive wastewater purification units for different wastewater components. Can effectively remove COD and water treatment from wastewater. This product has the advantages of excellent technology, high degree of automation, no need for dedicated personnel, good processing effect, small installation space, and convenient operation and maintenance.

Process flow: Experimental wastewater collection pipeline network - Raw water collection - Electrolytic treatment - Regulating treatment (pH adjustment, ozone, COD decomposition, flocculation and sedimentation) - MBR membrane deep treatment - UV treatment - Microfiltration treatment - Discharge

Laboratory wastewater contains acids, alkalis, organic pollutants, heavy metal ions, and pathogenic microorganisms. The pH value varies greatly and the COD concentration is high. It is mainly divided into three categories:

1. Organic wastewater: The main sources are experimental reagents and solvents.

2. Inorganic wastewater: The main sources are acid-base reagents and heavy metal reagents.

3. Biological pathogenic wastewater: The main sources are microorganisms, blood biochemistry experiments, blood stations, disease control centers, etc.

Equipment features:

1. Highly integrated: The equipment adopts a modular design, tightly integrating various processing units together, occupying a small area, and easy to install.
2. Fully automatic operation: The equipment is equipped with an intelligent control system that can automatically adjust operating parameters according to sewage quality and treatment requirements, achieving fully automated operation.
3. High treatment efficiency: The equipment combines multiple sewage treatment processes, such as biofilm method, activated sludge method, etc., and has the ability to efficiently remove pollutants.
4. Energy saving and environmental protection: The equipment has low noise and energy consumption during operation, and the amount of sludge generated during the treatment process is small, reducing secondary pollution to the environment.
5. Easy to maintain: The device has a simple structure, is easy to maintain, and can greatly reduce operating costs.

Factory laboratory wastewater and sewage treatment equipmentEquipment working principle:

1. Sewage collection: Collect the sewage generated in the laboratory into the equipment through pipelines.
2. Pre treatment: Preliminary treatment of sewage, such as grid slag removal, water quality regulation, etc., to provide favorable conditions for subsequent treatment.
3. Biochemical treatment: Using biological treatment technologies such as biofilm or activated sludge, organic matter, nitrogen, phosphorus and other pollutants in wastewater are removed through microbial metabolism.
4. Advanced treatment: Using physical, chemical, or biological methods to further remove recalcitrant substances, heavy metal ions, etc. from wastewater.
5. Disinfection and discharge: Disinfect the treated sewage to ensure that the water quality meets the discharge standards before discharging it into the environment.

Widely used in domestic research institutes, universities, monitoring, product inspection, food inspection, entry-exit inspection and quarantine, disease control centers, geological and mineral centers, analysis centers, water resources monitoring, grain and oil quality inspection, petrochemicals, animal husbandry, agricultural product inspection, central blood stations, enterprises and other industry laboratories, laboratory wastewater treatment.
