Equipment Introduction:
The comprehensive wastewater treatment equipment for laboratories processes agricultural production system, inorganic, and biological wastewater through units such as wastewater collection, automatic adjustment, coagulation-air flotation automatic mixing, flocculation-assisted sedimentation reaction, sedimentation separation, multi-stage high oxidation treatment, multi-stage decomposition degradation treatment, high/low potential difference micro-electrolysis technology, electrochemical oxidation-reduction, two-stage agricultural production system biological activity treatment technology, and new biochemical reaction treatment technology. It effectively removes COD, BOD, SS, color, and heavy metal ions from the wastewater. Different treatment technologies and control systems are employed based on the composition of various laboratory wastewater types. The equipment operates via an operating system, following the programs set by the controller and parameters set by the pH/ORP meter.
Features of Laboratory Water Treatment Equipment:
1. Capable of nitrogen and phosphorus removal, able to meet the requirements for treating industrial wastewater, domestic wastewater, and urban wastewater by adjusting the equipment structure.
2. The equipment has strong impact load resistance, with an average residence time in the contact oxidation process exceeding 6 hours.
3. Equipment effluent water quality is stable, with minimal sludge production and easy handling.
4. The equipment in the contact oxidation tank is equipped with an aeration blower for aeration, which allows the fibers to continuously float and ensures even aeration. This promotes the growth and maturation of microorganisms within the tank, exhibiting characteristics of the activated sludge process.
5. Water treatment equipment can be placed above ground or buried underground. It reduces land occupation and saves on land usage. When buried, the top can be covered with greenery.
6. In addition to conventional silencing measures with blowers, the blower room interior walls are lined with new sound-absorbing materials, ensuring the equipment operates at noise levels below 50 decibels, thereby minimizing impact on the surrounding environment.
7. Submersible pumps can be installed within the equipment, cost-effective.
8. Easy to operate, convenient, labor-saving, with both manual and automatic operation options.
Equipment Process:
Wastewater is collected through the sewage pipeline and stored in an external storage tank for uniform water quality regulation and preliminary sedimentation of large particles. An internal float ball sensor detects water level, and once it reaches the set high water level, it is transported to the main equipment via an external lift pump. It first enters the PH adjustment tank, controlled by a PH detector (parameters are factory-set, but can be adjusted according to actual conditions) to automatically adjust the PH by adding acid or alkali. After PH adjustment, it flows into the micro-electrolysis tank, where it undergoes electrolysis through internal potential differences, reducing COD and removing some heavy metal ions. It then sequentially enters the flocculation sedimentation tank, where it is flocculated and sedimented by adding PAC or PAM, reducing SS. It flows into the clear water tank and, upon reaching a certain water level, is automatically pumped to a multi-media filter for adsorption filtration. It then enters a slow-release disinfection unit for disinfection treatment. After treatment, the wastewater meets the first, second, and third-level standards of the Comprehensive Discharge Standard for Wastewater of GB8978-1996. The treated wastewater can be discharged into the municipal sewage system or surface water bodies, or can be reused through further treatment processes.
Application Range of Laboratory Wastewater Treatment Equipment:
A highly automated, efficient, and space-saving comprehensive wastewater treatment system for laboratories, suitable for various industries at home and abroad. This system is praised by users for its simplicity in operation and management, and does not require dedicated staff. It is widely used in universities, research institutions, food and drug inspections, product quality testing, disease control centers, environmental monitoring, agricultural product inspections, inspection and quarantine, grain and oil testing, animal disease control, blood stations, animal husbandry, health institutions, hospitals, pharmaceuticals, petrochemical industries, and other laboratories and化验室. The treated wastewater meets the first, second, and third-grade standards of the Comprehensive Wastewater Discharge Standard (GB8978-1996). The treated wastewater can be discharged into the municipal sewage system or surface and river water, or it can be reused through further treatment processes.
