The middle school laboratory sewage treatment equipment is an integrated and modular treatment device that integrates multiple technologies. Suspended solids are removed through precipitation and filtration, colloids and some heavy metals are removed through coagulation precipitation, toxic organic compounds are treated through oxidation-reduction, and advanced treatment technologies such as activated carbon adsorption and membrane filtration may also be used. It can effectively treat various pollutants such as acid and alkali, heavy metal ions, and some organic solvents. It integrates a PLC control system to achieve online pH monitoring, automatic dosing, fault alarms, and other functions. The effluent quality is more likely to meet discharge standards or reuse requirements.
High school laboratory sewage treatment equipmentThe product performance is designed around core dimensions such as treatment effect, operating efficiency, intelligence level, safety and environmental protection, and is suitable for scenarios such as small discharge of experimental wastewater in middle schools, mixed components, and intermittent production. Different types of equipment have their own emphasis on performance, and the overall performance characteristics are as follows:
Purification processing capability
Targeted removal of multiple types of pollutantsUsing multiphase catalytic oxidation and micro nano aeration technology, the efficiency of oil degradation exceeds 92%; Its pulse ion exchange module has an adsorption capacity of 35mg/g for metal ions such as Fe ³ ⁺ and Cu ² ⁺, far exceeding that of ordinary resins. It can handle various heavy metals such as mercury and chromium, decompose organic matter, and remove microorganisms such as viruses and fungi in biological laboratories through ultraviolet or ozone disinfection.
The effluent quality meets the standard and is stableMost devices can ensure that the effluent quality meets the requirements of the Comprehensive Wastewater Discharge Standard GB8978-1996.
Performance of operational efficiency
Adapt processing speed to the pace of class hoursHigh school experimental wastewater is mostly generated after class, and the equipment is suitable for small batch rapid treatment.
Energy saving and consumption reducing adaptation to intermittent scenariosConsidering that there is no wastewater generated during non class hours, many devices have intelligent sleep functions.
Intelligence and operational performance
Automated control is precise and convenientMainstream equipment is equipped with PLC control system and high-precision sensors
Complete remote and security monitoringSome devices are equipped with 4G IoT or WIFI modules, supporting remote control and monitoring through mobile phones. At the same time, it is equipped with multiple protection functions, such as water leakage protection, high and low voltage protection, and liquid level protection of the storage tank. When abnormalities occur, it will automatically alarm and take measures such as shutdown to reduce operational risks.
Adaptation and safety performance
Strong adaptability and easy maintenanceAdopting modular design, it can adapt to experimental wastewater from different disciplines such as physics, chemistry, and biology. And the equipment is mostly of integrated structure, with commonly used acid and alkali resistant U-PVC or PP materials for the shell. The structure is compact, occupies a small area, and is convenient for installation, maintenance, and upkeep.
Safety design tailored to teaching scenariosTo avoid affecting classroom teaching, a closed silent structure is adopted, with operating noise below 45 decibels; Its ozone disinfection module is only activated after class to prevent gas leaks during breaks that could harm the health of teachers and students, comprehensively meeting the safety needs of campus teaching.
High school laboratory sewage treatment equipmentMost of them are integrated devices, and the operation process revolves around preparation, operation, and shutdown. At the same time, daily maintenance and troubleshooting need to be done well to adapt to the intermittent and mixed composition characteristics of middle school experimental wastewater. The specific instructions for use are as follows:
Preparation before use
Equipment and installation inspectionThe equipment needs to be installed in a flat, dry, and well ventilated area, and the power supply must be connected to the grounding wire. At the same time, check whether the pipeline connections are tight and leak free, whether the valves are in the correct opening and closing positions, whether the pump body, sensors, cables and other components are damaged, and whether the pressure gauge, electronic control device and other components are sensitive and accurate.
Preparation of consumables and pharmaceuticalsSupplement sufficient amount of required chemical agents, such as acid-base regulators, coagulants, heavy metal scavengers, etc; If the equipment is equipped with disinfection function, it is necessary to confirm that the disinfection components such as ultraviolet lamps and ozone generation modules are intact, and the medicine container should be covered and sealed to prevent foreign objects from falling in.
Parameter pre understandingClarify the equipment processing capability to avoid excessive water ingress. At the same time, based on the type of experimental wastewater on the day, determine the approximate pH adjustment range, dosage and other basic parameters in advance.
Core operating procedures
Power-On Self-TestPress the power switch, and the device will automatically enter self-test mode. After the self-test is completed and the standby state is displayed, the processing time, dosage, pH target value and other parameters can be set through the touch screen or control panel.
-
Import wastewaterIntroduce laboratory wastewater into the equipment inlet through a dedicated pipeline, avoiding the introduction of large solid waste, large amounts of grease, etc. during the process to prevent blockage of pipelines and equipment. If there are obvious solid impurities, they can be manually filtered before being introduced.
automatic processingAfter receiving wastewater, the device starts the preset program and completes the steps of physical filtration, chemical reaction, disinfection, etc. in sequence. During this period, the processing status can be observed through the monitoring interface, such as pH value, reaction time, and other data. If there are parameter abnormalities, the equipment will automatically adjust or give an alarm prompt.
compliance dischargeAfter processing, the equipment is drained through the outlet. During drainage, water quality monitoring data can be checked to confirm that the pH value is between 6-9 and there are no obvious impurities or odors before discharging into the campus sewage pipe network.
Shutdown and subsequent operations
Standardize shutdownStop the water intake first, wait for the residual wastewater in the equipment to be completely treated and discharged, then turn off the treatment module and disinfection module in sequence, and finally disconnect the power supply. Long term shutdown requires emptying the medication in the dosing device and the liquid in the pump, and rinsing with clean water.
Basic cleaningClean the impurities in the inlet filter of the equipment, wipe the equipment casing, keep the surrounding environment clean, and avoid the accumulation of debris that may affect the next use.
Daily maintenance and precautions
regular maintenanceRegularly clean sedimentation tanks, filters, and other components to avoid blockages; Clean the medicine box once a month or every quarter, and regularly calibrate pH sensors and other components; Replace consumables such as filter cartridges and aging pipes according to usage frequency.
Safety NoticeWear protective gloves during operation to avoid direct contact with chemical agents and wastewater; If there is any abnormality such as water leakage, abnormal noise, or alarm during the operation of the equipment, immediately stop the machine and cut off the power for troubleshooting. It is forbidden to operate with faults.
Record retentionBriefly record the source of wastewater, treatment duration, dosage of chemicals, and effluent quality for each treatment, to facilitate subsequent troubleshooting and parameter optimization.
