Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device and process for simultaneous membrane separation and biodegradation cycle. Background Technology

[0002] When treating wastewater generated during silicone oil production, the pH value needs to be adjusted in a wastewater equalization tank. After adjustment, the wastewater enters the demulsification and oil removal unit. The oil-removed wastewater enters the bioreactor, where the microorganisms in the wastewater are degraded. The degraded wastewater then enters the membrane separation zone, where PVDF hollow fiber ultrafiltration membranes intercept sludge, macromolecular organic matter, siloxanes, suspended solids, and other contaminants in the wastewater.

[0003] For example, CN109111013B discloses a method for treating wastewater containing water-soluble silicone oil generated during organosilicon production: after sedimentation in an oil separator for 48 hours, the floating scum at the top and the sedimented silica powder at the bottom are separated using a horizontal screw press; the wastewater containing water-soluble silicone oil is adjusted to pH 3-4 and then centrifuged to remove the precipitated silicone oil; the separated wastewater is subjected to air flotation for impurity removal and deep oxidation to oxidize the silicone oil dissolved in the wastewater into silica gel, and then a plate and frame filter press is used to remove the silica gel. The resulting saline wastewater is dehydrated by a triple-effect evaporator and used as a raw material for ion-exchange membrane caustic soda. This invention uses advanced equipment such as a horizontal screw press and a triple-effect evaporator to directly oxidize the water-soluble silicone oil in the wastewater into silica gel, with a conversion rate of over 99%. The biochemical properties of the treated wastewater are not less than 0.29, facilitating biochemical treatment. The wastewater treated by this invention meets national discharge standards, and the generated silica gel and crude salt can be used as downstream raw materials for organosilicon and caustic soda, demonstrating high practical value.

[0004] However, during the treatment process, wastewater first enters the bioreactor. After the pollutants are degraded, it needs to be transferred to the membrane separation zone through pipelines for solid-liquid and oil-water separation. The wastewater transfer process takes a long time, which affects the wastewater treatment efficiency. At the same time, sludge settling and silicone oil re-emulsification are likely to occur during the wastewater transfer process, resulting in a high risk of membrane fouling. Summary of the Invention

[0005] In view of this, the present invention provides a wastewater treatment device and process for simultaneous membrane separation and biodegradation cycle. It utilizes multiple baffles to divide the wastewater into an aerobic degradation zone, an anoxic denitrification zone, and an anaerobic hydrolysis zone. Simultaneously, the membrane module support is directly bolted to the aerobic degradation zone and the membrane module is suspended, achieving in-situ coupling of biodegradation and membrane separation. This avoids the need to transfer wastewater through pipelines between the bioreactor and membrane separation zone, effectively shortening the overall wastewater treatment process, saving significant time, and improving treatment efficiency. It also avoids sludge settling and silicone oil re-emulsification during wastewater transfer, reducing the risk of membrane fouling and extending the membrane module's lifespan. The reciprocating self-locking drive on the water quality equalization tank rotates the agitator, ensuring more uniform pH adjustment and stable operation of subsequent treatment processes. The demulsification reaction tank, combined with a settling inclined plate, enables preliminary sludge settling. The coordinated setup of the heated demulsification tank, centrifuge, and silicone oil storage tank not only efficiently separates silicone oil from the wastewater for resource recovery but also... The residual liquid after centrifugation is returned to the water quality equalization tank for reprocessing, achieving wastewater reuse and reducing resource waste. The coordinated use of the chemical washing tank, backwash pump, and water collection pipe enables timely and effective backwashing maintenance of the membrane module, ensuring the continuity of membrane separation performance. The mixed liquor return pump and sludge return pump transport the mixed liquor and sludge to the anoxic denitrification zone and anaerobic hydrolysis zone of the integrated reactor, respectively, achieving the recycling of sludge and mixed liquor, maintaining the stability of the microbial community within the reactor, and improving biodegradation efficiency. (Fan installation...) The linkage between the tank, airflow collection box, and microporous aeration components provides uniform and sufficient aeration to the integrated reactor, ensuring the degradation effect in the aerobic degradation zone. At the same time, the airflow generated by aeration can also purge the membrane module, reducing the adsorption of pollutants on the membrane surface and further reducing the probability of membrane fouling. The cooperation of the linear module, oil skimmer, and oil scraper can efficiently collect the floating oil in the demulsification reaction tank and guide it into the oil collection tank, and then transport it to the heated demulsification tank for subsequent treatment, improving the efficiency of oil-water separation and preventing floating oil from entering the subsequent treatment process and affecting the treatment effect.

In the aerobic degradation zone, the degraded wastewater is simultaneously separated by membrane modules suspended on the membrane module support to achieve efficient retention of sludge, macromolecular organic matter, siloxanes, and suspended solids. S5. Airflow is generated by the aeration blower in the blower installation box. After being evenly distributed by the airflow collection box, the airflow is released into the integrated reactor through the microporous aeration element. This provides an aeration environment for the aerobic degradation zone and at the same time, the airflow is used to sweep the surface of the membrane module to reduce pollutant adsorption. S6. The sludge retained by membrane separation is returned to the anaerobic hydrolysis zone of the integrated reactor via the sludge return pump and the mixed liquor is returned to the anoxic denitrification zone of the integrated reactor via the mixed liquor return pump and the mixed liquor is returned to the anoxic denitrification zone of the integrated reactor via the mixed liquor return pump, so as to maintain the stability of the microbial community and high sludge concentration in the reactor. S7. The purified permeate after membrane separation is collected through a water collection pipe by a permeate pump to complete the treatment of silicone oil production wastewater. The cleaning solution in the chemical washing tank is periodically transported to the membrane module through a water collection pipe by a backwash pump to perform online backwashing maintenance on the membrane module.
