Intelligent Integrated Waste Liquid Treatment Equipment

The physical method employs advanced nanofiltration treatment processes both domestically and internationally. It features minimal sludge production, concentrated water recirculation, and essentially meets zero discharge standards. As a novel membrane separation technology, nanofiltration separation operates on a principle similar to mechanical sieving. However, nanofiltration membranes inherently carry an electrical charge. This is a key reason why they maintain high desalination performance even at very low pressures and can remove inorganic salts even when intercepting substances with molecular weights in the hundreds. Compared to ultrafiltration or reverse osmosis, process determination

The use of special treatment processes can be divided into two parts: a combination of biochemical and physical methods. The biochemical method is SBR, also known as Sequencing Batch Reactor Activated Sludge Process. SBR is an acronym for Sequencing Batch Reactor Activated Sludge Process, a wastewater treatment technology that operates on an intermittent aeration basis, also referred to as sequential batch activated sludge process. Unlike traditional wastewater treatment processes, SBR technology uses time-segmented operation instead of space-segmented operation, unsteady biochemical reactions instead of steady-state biochemical reactions, and ideal static sedimentation instead of traditional dynamic sedimentation. Its main characteristic is ordered and intermittent operation. The core of SBR technology is the SBR reaction tank, which integrates functions such as equalization, primary sedimentation, biodegradation, and secondary sedimentation in a single tank, with no sludge return system. The ideal plug-flow process increases the driving force of biochemical reactions, improves efficiency, and alternates anaerobic and aerobic conditions within the tank, resulting in excellent purification effects. Stable operation, ideal static sedimentation of wastewater, short required time, high efficiency, and good effluent quality. It withstands impact loads, with滞留 treatment water in the tank that dilutes and buffers wastewater, effectively resisting shocks from water volume and organic pollutants. Each step in the process can be adjusted based on water quality and quantity, offering flexible operation. Concentration gradients of DO and BOD5 in the reaction tank effectively control activated sludge expansion. Nitrogen and phosphorus removal: by appropriately controlling the operation mode, alternating aerobic, anoxic, and anaerobic states achieve good nitrogen and phosphorus removal effects. Compared to the nanofiltration process, it has poorer interception of monovalent ions and organic matter with molecular weights below 200, but higher removal rates for divalent or polyvalent ions and organic matter with molecular weights between 200 and 500. Based on this characteristic, the nanofiltration process is mainly used for water softening, purification, and the separation, classification, and concentration of substances with relative molecular weights in the hundreds (such as dyes, antibiotics, peptides, polysaccharides, etc., in chemical and bioengineering products), decolorization, and deodorization. It is primarily used to remove hardness components like Ca and Mg ions, trihalomethane intermediates, odors, color, pesticides, synthetic detergents, soluble organic matter, and evaporation residues from drinking water. NF separation is a green water treatment technology that can, in some aspects, replace traditional wastewater treatment methods that are costly and involve complicated processes. Its technical features include: intercepting organic matter with molecular weights greater than 100 and polyvalent ions, allowing small molecular organic matter and monovalent ions to pass through; capable of operating under harsh conditions such as high temperature, acid, and alkali, with good pollution resistance; low operating pressure, high membrane flux, and low operating costs; can be combined with other wastewater treatment processes to further reduce costs and improve treatment efficiency. In water treatment, NF membranes are mainly used for treating solvent-containing wastewater, effectively removing color, hardness, and odors from water. NF membranes have been successfully applied in wastewater treatment in industries such as sugar production, pulp and paper manufacturing, electroplating, mechanical processing, and the recovery of chemical reaction catalysts due to their unique separation properties.

The entire process system control of this wastewater treatment system uses imported Schneider PLC as the central controller, mainly controlling the switching between submersible sewage pumps in the regulation tank, blowers, and the chemical dosing system.

1) Detect pH value; if high, start acid dosing; if low, start alkali dosing; adjust pH to 9.

2) Detect high liquid level in the regulation tank; at high level, open the inlet valve and wastewater lift pump,同时 start chemical A dosing pump and blower.

3) Detect low liquid level for ammonia nitrogen; when there is liquid level, start chemical B dosing pump.

4) Detect low liquid level for ammonia nitrogen; when there is liquid level, start PAC chemical dosing pump.

5) Detect low liquid level in the flocculation reaction tank; when there is liquid level, start the filtration pump.

6) Detect high liquid level in the clean water tank; at high level, start the membrane inlet solenoid valve and raw water pump for membrane intake; the ultrafiltration rinse valve activates every 10 minutes for 10 seconds.

7) Detect high liquid level in the intermediate tank; at high level, start the high-pressure pump.
