Environmental protection equipment for acid-base wastewater treatment in small university laboratories

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.

Features and advantages:

1. Compact design, small space

Adopting an integrated structure, occupying only 1-3 square meters, it can be flexibly installed in laboratory corners, equipment rooms, or outdoor open spaces without affecting teaching space planning. Modular design supports quick disassembly and assembly, adapting to the limited space conditions of junior high school laboratories.

2. Intelligent operation, zero pressure management

Fully automatic control: equipped with a specialized intelligent control system for junior high school laboratories, it automatically identifies the composition of wastewater and adjusts treatment parameters without the need for manual supervision, reducing the additional workload of teachers.

3. Safety standards are met, and there are no hidden dangers in emissions

In response to common issues such as acid-base imbalance and heavy metal residue in junior high school experiments, the equipment uses a real-time water quality monitoring system to ensure that every drop of water meets national standards. The treated clean water can be directly discharged or reused, cutting off the pollution chain from the source and safeguarding the safety of campus water environment.

Environmental protection equipment for acid-base wastewater treatment in small university laboratories 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.
