Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a water quality control device based on mesophilic microorganisms for efficient treatment of dyeing and printing wastewater. Background Technology

[0002] Wastewater from dyeing and printing contains complex pollutants, including recalcitrant organic matter such as azo dyes and anthraquinone dyes. It exhibits high color intensity (ADMI > 500), large pH fluctuations (acidic or alkaline), and high salinity (e.g., ...). , Concentrations can reach 5-10 g / L), heavy metals (such as...) , The traditional physicochemical methods (such as coagulation and adsorption) are costly, while biological methods are easily inhibited by toxicity and produce large amounts of sludge.

[0003] Although the core microorganisms currently used to treat dyeing and printing wastewater, such as *Pseudomonas putida*, *Bacillus subtilis*, *Phanerochaete chrysosporium*, and *Chlorella vulgaris*, are mesophilic microorganisms—microorganisms that cannot grow at high (50°C) or low (5°C) temperatures, but survive and grow at moderate temperatures (20–50°C)—they still exhibit high activity and low energy consumption without requiring additional heating or cooling. However, the formaldehyde in dyeing and printing wastewater... The high osmotic pressure of dyeing and printing wastewater inhibits microbial activity, leading to cell dehydration and affecting the activity of enzymes that degrade organic matter. Furthermore, anthraquinone dyes have a stable structure and a low degradation rate. To address these issues, it is necessary to add appropriate wastewater treatment agents to the wastewater or add appropriate functional microbial agents for the biodegradation stage during the dyeing and printing wastewater treatment process. Controlling water quality conditions is also essential to achieving the goal of wastewater purification. Utility Model Content

[0048] In this embodiment, as Figure 1As shown, the circulating water outlet pipe 203, inlet pipe 8, drain pipe 9, liquid addition pipe 17, exhaust pipe 20, and sludge removal pipe 23 are respectively equipped with a first valve 28, a second valve 29, a third valve 30, a fourth valve 31, a fifth valve 32, and a sixth valve 33.

[0049] In this embodiment, as Figure 1 As shown, the PLC controller 10 is installed inside the control cabinet 26. A touch screen 27 is provided on the outer wall of the control cabinet 26. The touch screen 27 is electrically connected to the PLC controller 10. Instructions can be input to the PLC controller 10 through the touch screen 27, and the PLC controller 10 transmits the detection results of each sewage parameter detection component to the touch screen 27 and displays them on the touch screen 27.

[0050] like Figure 4 As shown, the working principle of this utility model is as follows: Before use, under the control of the PLC controller 10, the second valve 29 of the inlet pipe 8 is opened and the second water pump 14 is started to transport the sewage to be treated into the reactor 1. The detection components such as temperature sensor 301, ammonia nitrogen sensor 302, pH value sensor 303, oxidation-reduction potential sensor 304 and dissolved oxygen concentration sensor 305 detect the sewage parameters and feed back the detection data to the PLC controller 10.

[0051] When in use, wastewater treatment is divided into the following stages: (1) Pretreatment stage: By detecting the oxidation-reduction potential through the oxidation-reduction potential sensor 304, it can be found that there are oxidation-reduction potentials in the wastewater. (2) Stabilization stage: At this time, after opening the fourth valve 31 of the liquid addition pipe 17, start the fourth water pump 16, add the corresponding heavy metal ion capture agent, and at the same time start the stirring motor 19 to mix the heavy metal ion capture agent with the sewage evenly, so that the heavy metal ion capture agent reacts fully with the heavy metal ions to remove the corresponding heavy metal ions; (3) Degradation reaction stage (since the dyeing and printing sewage contains a large amount of organic matter, the anaerobic reaction is performed first and then the aerobic reaction is performed): ① Anaerobic reaction stage: After opening the fourth valve 31 of the liquid addition pipe 17, start the fourth water pump 16, add betaine and trehalose to stabilize the microbial activity generated by the activated sludge; ① In the anaerobic reaction stage: Wastewater treatment agent required for the anaerobic reaction is added. Simultaneously, based on the pH value detected by pH sensor 303, pH adjuster is added to adjust the wastewater pH to the required level for the anaerobic reaction. Then, stirring motor 19 is started to uniformly mix the wastewater treatment agent, pH adjuster, and wastewater, ensuring complete anaerobic reaction. ② In the aerobic reaction stage: If the ammonia nitrogen value detected by ammonia nitrogen sensor 302 is high, the fourth valve 31 of the liquid addition pipe 17 is opened, and the fourth water pump 16 is started. The bacterial agent required for the aerobic reaction is added. Simultaneously, the first valve 28 of the circulating water outlet pipe 203 is opened, and the first water pump 13 is started. This allows the water in the jacket 7 to pass through the circulating water outlet pipe, heat exchange processor 201, and circulating inlet / outlet pipe 8, ensuring that reactor 1 is kept at a constant temperature. In the water bath, the aerobic reaction is maintained at the activity temperature of the bacterial agent. At the same time, the blower 401 is started after the air inlet pipe 24 is opened. The PLC controller 10 detects the dissolved oxygen concentration according to the dissolved oxygen concentration sensor 305, and the air supply data of the blower 401 collected by the air flow meter 404 and the pressure monitoring instrument 402. The blower controller 11 adjusts the speed of the blower 401 to achieve the dissolved oxygen concentration required for the aerobic reaction. Then the stirring motor 19 is started to mix the bacterial agent and the sewage evenly so that the aerobic reaction is complete. The generated gas is discharged from the exhaust pipe 20. (4) Anthraquinone dye degradation stage: After opening the fourth valve 31 of the liquid addition pipe 17, the fourth water pump 16 is started to add laccase and horseradish peroxidase. At the same time, according to p H value sensor 303 detects pH value and adjusts wastewater pH value to 5-6 by adding pH value adjuster. After opening the first valve 28 of circulating water outlet pipe 203, the first water pump 13 is started, so that the water in the jacket 7 passes through the circulating water outlet pipe, heat exchange processor 201 and circulating water inlet pipe 8 in turn, so that the reactor 1 is in a constant temperature water bath, and the wastewater temperature is adjusted to 40-45℃. Then the stirring motor 19 is started to mix laccase, horseradish peroxidase and anthraquinone dye evenly, so that the enzyme reaction is complete and the anthraquinone dye is completely degraded; (5) Activated sludge sampling: During the wastewater treatment process, the sixth valve 33 of sludge sampling pipe 23 is opened, and sludge is sampled according to actual needs, so as to facilitate detection and analysis and obtain the actual sludge properties;

[0052] Finally, after the wastewater undergoes multi-stage treatment, multiple detection components detect that its relevant parameters meet the discharge standards. After the third valve 30 of the PLC controller drain pipe 9 is opened, the third water pump 15 is started to transport the treated wastewater to the outside of the reactor 1.

[0053] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
