Reagents and pharmaceuticals used in the laboratory number in the dozens to thousands, depending on the variety. Currently, the school offers multiple experimental courses, including tests for verifying the properties of substances, quantitative analysis experiments, organic synthesis experiments, and organic extraction experiments, among others. The chemical reagents used include common acids, bases, heavy metal salts, and phenols along with their organic compounds. Most of these can cause severe environmental pollution. Many reagents and their reaction waste products, such as various acids, bases, heavy metal salts, and organic substances, are harmful to both the environment and human health. Some of these substances can persist in the environment for a long time, being difficult to degrade; others accumulate in the food chain and cause toxic effects in the human body; and some even cause secondary pollution during the degradation process.

The challenges in laboratory wastewater treatment are mainly reflected in the following aspects:
Composition complex: Wastewater from different experiments exhibits significant differences in nature, requiring targeted treatment.
2. Intermittent Emissions: The wastewater discharge volume is unstable, requiring the design of a buffer and regulation system.
3. High toxicity: Although some pollutants have low concentrations, they possess extreme toxicity and require deep treatment.
4. High technical threshold: Requires integration of multidisciplinary technologies such as chemistry, biology, and physics.

Mature technology for laboratory wastewater treatment equipment:

1. After considering various factors, the school laboratory's wastewater treatment equipment adopts a mature technology with low investment, stable operation, low running costs, and good treatment effectiveness.

2. In response to the characteristics of wastewater, the school's laboratory wastewater treatment equipment employs specific countermeasures to ensure the removal of harmful components, while fully considering anti-corrosion measures for pipelines, equipment, and structures.

3. Select equipment for school laboratory wastewater treatment that features stable performance, easy maintenance, reasonable pricing, durability, and high treatment efficiency.

Building layout is rational and compact, aesthetically pleasing, and aims to minimize land usage.

5. The school laboratory wastewater treatment equipment has certain capacity to withstand shock loads in terms of water quality and quantity.

6. The design fully considers noise and odor, preventing the generation of secondary pollution. The school laboratory wastewater treatment equipment does not cause new pollution to the surrounding environment.

7. Achieve automated control to enhance stability; ensure the effluent quality meets standards for school laboratory wastewater treatment equipment.

Laboratory wastewater treatment primarily employs physical, chemical, and biological methods, as well as their combined processes. Specific technologies include:
Physical Processing Technology
Settling and Filtration: Removes suspended solids through grates, sand filters, etc., suitable for the pre-treatment stage.
Adsorption Method: Utilizes activated carbon, zeolite, and other adsorbents to remove organic matter and certain heavy metals.
Membrane separation technology: Ultrafiltration, reverse osmosis, etc., can effectively retain micro-particles and dissolved pollutants.
2. Chemical Treatment Technology
Neutralization reaction: Adjust pH value by adding acid or alkali to prevent corrosion or failure of subsequent biological treatment.
Oxidation-Reduction: Utilizes ozone and other oxidizing agents to degrade organic pollutants, or to reduce heavy metal ions.
Coagulation and Sedimentation: Add chemicals such as polymer (PAC) and polyacrylamide (PAM) to cause colloidal particles to coagulate and settle.
3. Biological Treatment Technology
Biofilm Method: Utilizes microorganisms to degrade organic matter, suitable for low-toxicity organic wastewater.
Anaerobic digestion: Treats high-concentration organic wastewater, yielding recyclable materials.

Key Points for Operation, Maintenance, and Management:
Regular Monitoring: Inspect equipment operation daily and water quality weekly.
2. Pharmaceutical Management: Standardize the storage of hazardous chemicals such as acids, bases, and oxidizers, and avoid cross-contamination.
3. Sludge Disposal: Sedimented sludge must be entrusted to a professional agency for hazardous waste management.
Emergency Response Plan: Equipped with leak collection ponds and emergency neutralizers to prevent accidental discharges.
