Wastewater generated from experiments is collected by the collection system and first flows into the equalization pond and the laboratory's wastewater treatment equipment to adjust water volume and homogenize water quality. Once the water level in the equalization pond reaches a certain height, it is pumped quantitatively to the post-treatment unit. In the integrated wastewater treatment equipment, the wastewater first enters the acid-base neutralization equalization system for neutralization. In the laboratory's biological wastewater treatment equipment, pH is precisely adjusted to 8-9 by adding sodium hydroxide solution or citric acid solution with a metering pump. Under alkaline conditions, if heavy metal ions such as iron, cadmium, copper, manganese, nickel, lead, and chromium are present in the wastewater, they react with OH- to form hydroxide precipitates. These precipitates, along with other suspended solids in the wastewater, are flocculated and settled in the sedimentation pond where PAC/PAM flocculant aids are added. After acid-base neutralization, the resulting precipitates and other suspended solids in the wastewater are flocculated and settled in the sedimentation pond to separate sludge from water, ensuring the achievement of the required suspended solids standards.

General Principles for Laboratory Treatment of Wastewater:

1. Upon proving that waste has become sufficiently scarce and safe, it can be released into the atmosphere or drainage; strive to concentrate the waste liquid to reduce volume and store it in a secure location in isolation; utilize methods such as distillation, filtration, and adsorption to separate hazardous materials, discarding only the safe portions; regardless of liquid or solid, anything that can be safely burned should be, but in moderate quantities, ensuring no harmful gases or residues remain during combustion; if incineration is not feasible, opt for a safe location for landfilling, avoiding exposure on the ground.

2. Toxic gases can generally be expelled by ventilation hoods or ducts, after being diluted in the air. Large amounts of toxic gases must be combusted with oxygen or processed by adsorption before排放.

3. Wastewater should be stored in appropriate containers and locations based on its chemical properties, using sealed containers, and should not be mixed for storage. Clearly label the type, storage duration, and schedule for regular disposal.

3. Accurately control dosing quantity using a pH meter and imported metering pump.

4. Easy to operate, stable performance, long service life, and low operation and maintenance costs.

5. Compact in size, suitable for installation indoors or outdoors as per different circumstances.

6. Tailor-made design and manufacturing based on different customer requirements.

Process Description:

Wastewater is collected and homogenized in a sedimentation tank, then flows into a neutralization reactor where a measured amount of acid (or alkali) solution is added based on the water quality characteristics for neutralization. The neutralized wastewater is then pumped to a filtration tank for filtration. During this process, a measured amount of净水剂 solution is also introduced to cause flocculation of pollutants in the wastewater, enhancing the filtration efficiency. The filtered clean water is sterilized by an ozone sterilizer before flowing into a biological activated carbon tank, where fine pollutants are further intercepted and adsorbed for decomposition. The treated clean water is then directly discharged into the city's sewage network.

Working Principle:

Laboratory wastewater treatment equipment primarily utilizes coagulation, sedimentation, oxidation, and high-efficiency sterilization to remove and eliminate bacteria, heavy metals, COD, viruses, and other contaminants from biological wastewater. Within a certain pH range, it can kill all microorganisms, including bacterial propagules, bacterial spores, fungi, mycobacteria, and various infectious viruses such as hepatitis viruses. The wastewater treatment process employs automatic control, with the entire process requiring no constant supervision by personnel.
