Quankun 500L integrated fully automatic laboratory sewage treatment equipment

With the rapid development of the economy and continuous progress of technology, scientific research institutions and universities in various regions are conducting increasingly in-depth and extensive scientific experiments, and the discharge of laboratory wastewater from laboratories is gradually increasing. The water quality of laboratory wastewater is complex, the discharge cycle is irregular, the discharge volume is irregular, and the composition of pollutants is relatively complex. In addition to organic substances such as detergents and commonly used solvents, there are also many acids, bases, toxic and harmful organic substances, and heavy metals. Although the amount of laboratory wastewater is relatively small, if it is discharged directly without treatment, it will cause great pollution to the environment. Therefore, it is imperative to study methods for comprehensive treatment of laboratory wastewater and equipment with good treatment effects, advanced technology, and low investment. Jiangsu Quankun is a professional manufacturer of laboratory comprehensive wastewater treatment equipment. The company's R&D team has independently developed and produced a new type of high-efficiency integrated laboratory wastewater treatment equipment based on domestic laboratory wastewater discharge standards.

Quankun 500L integrated fully automatic laboratory sewage treatment equipment Process flow:

The laboratory cleaning wastewater is collected by the collection system and enters the regulating tank to regulate the water volume and homogenize the water quality. When the water volume in the regulating tank reaches a certain liquid level, it is quantitatively lifted to the laboratory integrated sewage treatment equipment by the lifting pump. In the integrated sewage treatment equipment, an acid-base neutralization adjustment system is introduced for acid-base neutralization. Here, a pH controller is used to accurately add a certain amount of NaOH aqueous solution using a metering pump, adjusting the pH value to between 8-9. Under alkaline conditions, the acid in the wastewater is neutralized. If the wastewater contains heavy metal ions such as iron, cadmium, copper, manganese, nickel, lead, chromium, etc., they can react chemically with OH - to form hydroxide precipitates. The effluent from the acid-base neutralization tank then flows into the sedimentation tank. The sediment generated after acid-base neutralization and other suspended solids in the sewage are separated from the sludge and water through the opposite flow between the sludge and water in the sedimentation tank.

The effluent from the sedimentation tank enters the ozone oxidation tank, intermediate water tank, and photocatalytic reactor in sequence. After oxidation, the wastewater finally enters the multi-media filter. The small suspended solids, trace metals, and very small amounts of organic matter that have not been removed are partially removed by physical and chemical processes such as adsorption and interception of quartz sand and activated carbon with a huge pore structure and specific surface area. The other part is degraded and removed by anaerobic, aerobic, and facultative bacteria attached to the microbial membrane on the activated carbon. The process of activated carbon interception and adsorption is interspersed, alternating, and circulating with microbial degradation and desorption. At this point, the wastewater can be discharged in compliance with the standard.

The entire wastewater treatment process is controlled by an automatic control system, and the neutralization regulation system is equipped with a float level control instrument. The pump stops automatically at low liquid levels and starts automatically at high liquid levels, which can basically achieve unmanned operation.Process characteristics:

1. Using technologies such as neutralization precipitation, ozone oxidation, photocatalytic reaction, and multi-media filtration to treat various pollutants in wastewater;2Using microcomputer programs to monitor and control real-time changes in wastewater quality and treatment processes, achieving 24/7 automatic operation without the need for dedicated personnel;

3. Accurately control the dosage of medication using a pH meter and imported metering pump;

4. The oxygenator used ensures sufficient contact between gas and water;

5. Easy to operate, stable in operation, long in service life, and low in operation and maintenance costs;

6. Small footprint, can be placed indoors or outdoors according to different situations;

7. Tailored design and manufacturing can be carried out according to different requirements of users.
