Small integrated product inspection and testing wastewater treatment equipment with PLC control

With the rapid economic development and continuous technological advancements, scientific research experiments conducted by research institutions and universities across regions are becoming increasingly in-depth and widespread. The amount of laboratory wastewater discharged from these labs is gradually increasing. The quality of laboratory wastewater is complex, with irregular discharge cycles and volumes, and it contains a complex mix of pollutants. Besides organic substances like detergents and common solvents, it also includes significant amounts of acidic and alkaline substances, toxic and harmful organic matter, and heavy metals. Although the volume of laboratory wastewater is relatively small, it can cause substantial environmental pollution if discharged untreated. Therefore, it is imperative to research comprehensive treatment methods for laboratory wastewater and equipment that offers effective treatment, advanced technology, and minimal investment.Jiangsu Puming is a professional manufacturer of comprehensive laboratory wastewater treatment equipment. Our R&D team has independently researched, developed, and produced a new type of high-efficiency integrated wastewater treatment equipment tailored to the domestic laboratory wastewater discharge standards. This equipmentPrinciples of Wastewater Treatment:

1Principle of whole-process control. Implement control over the entire process of wastewater generation, treatment, and discharge.

2Principle of reduction. Implement a strict laboratory unsanitary and unsafe management system, strictly control and separate wastewater and waste materials at a distance from the occurrence, separately collect domestic wastewater and industrial wastewater within the laboratory, and practice source control and separation of clean and dirty waste. Strictly prohibit the arbitrary disposal of laboratory wastewater and waste materials into the sewers.

3Principle of On-Site Treatment. To prevent contamination and hazards during the transportation of laboratory wastewater, on-site treatment must be conducted within the laboratory.

4Classification Guiding Principles. Provide classified guidance for laboratory wastewater treatment based on the nature, scale, destination of wastewater discharge, and regional differences.

5Principle of meeting standards and risk control. Considering the basic requirements for comprehensive laboratory and combustion laboratory wastewater to meet standards for discharge, while strengthening risk control, enhancing the ability to respond to sudden incidents in aspects such as process technology, engineering construction, and supervision and management.

6Eco-safety principles. Effectively remove harmful substances from wastewater, minimize the generation of disinfection by-products during treatment, and control excessive residual chlorine in the effluent, ensuring the safety of the ecological environment.

Process Flow:

The laboratory wastewater is first collected by the collection system and then enters the equalization pond to adjust water volume and homogenize water quality. Once the water level in the equalization pond reaches a certain height, it is quantitatively lifted to the laboratory integrated wastewater treatment equipment by a booster pump. In the integrated wastewater treatment equipment, it first enters the acid-base neutralization adjustment system for acid-base neutralization, where...pHControl instrument, accurately dosing a specific amount using a metering pumpNaOHAqueous solution, adjustedpHPlease provide the Chinese content to be translated.8～9Between, 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, and chromium, they can beOH-A chemical reaction occurs, forming a hydroxide precipitate.The effluent from the acid-base neutralization pond then flows into the sedimentation pond, where the sedimentation of the neutralized acid and alkali and other suspended solids in the wastewater are separated from the sludge and water through the counterflow between the mud and water in the sedimentation pond.The effluent from the sedimentation tank sequentially enters the ozonation oxidation tank, intermediate pond, and photocatalytic reactor. After oxidation, the wastewater flows into a multi-media filter. Fine suspended particles, trace metals, and a small amount of organic matter that have not been removed are eliminated through physical and chemical processes such as adsorption and retention by quartz sand and activated carbon with a large pore structure and high specific surface area. Another part is degraded and removed by anaerobic, aerobic, and facultative bacteria in the microbial film attached to the activated carbon. The process of activated carbon adsorption and retention alternates with microbial degradation and desorption. Upon this, the wastewater meets the standards for discharge.The entire wastewater treatment process is controlled by an automatic control system. The neutralization and adjustment system features a float ball level controller, which automatically stops the pump at low levels and starts it at high levels, enabling essentially unattended operation.
