Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a mobile PAD integrated wastewater treatment device. Background Technology

[0002] The existing wastewater treatment process includes toilet wastewater treatment, canteen wastewater treatment, and washing / shower wastewater treatment. 1. Toilet wastewater: It is separately connected to a septic tank, where suspended solids and some organic matter are removed through sedimentation and anaerobic fermentation (retention time ≥ 12 hours). 2. Canteen wastewater: It first passes through a grease trap to remove animal and vegetable oils (grease removal rate ≥ 80%) to prevent grease from clogging subsequent pipes or affecting the efficiency of treatment equipment. 3. Washing / shower wastewater: It is directly connected to the collection network and can be combined with pre-treated canteen wastewater and septic tank effluent. After the above wastewater treatment, it will enter the subsequent treatment unit for further treatment. If the construction site is ≤ 1km from the municipal sewage network and the network has the capacity to receive it, it can be connected to the municipal network for wastewater treatment. If it is located in a remote construction site or an area without a municipal sewage network, a small-scale wastewater treatment facility needs to be built. After treatment, it will be discharged into surrounding water bodies or reused for non-potable purposes.

[0003] Regarding the limitations of the "on-site processing" model:

[0004] 1. Projects vary in scale and implementation period, but wastewater treatment facilities are fixed and generally have a lifespan of more than 20 years. After the project is completed, the wastewater treatment facilities are abandoned, resulting in a huge waste.

[0005] 2. Limited adaptability to treatment scale: The number of construction personnel required varies greatly depending on the progress of the construction project. Fixed equipment is difficult to meet the increasing demand for sewage. If it is forced to operate under overload, it may lead to a decrease in treatment effect and accelerated equipment wear and tear.

[0006] 3. Limitations of on-site fabrication: On-site fabrication places higher demands on the site, environment, and processing equipment. This is especially true for small construction companies whose wastewater treatment facilities require significant design capabilities, which are often difficult to meet.

[0007] Therefore, a mobile PAD integrated sewage treatment device is proposed to solve the above problems. Utility Model Content

[0039] The working principle of this utility model is as follows:

[0040] Domestic sewage undergoes a preliminary treatment process to filter out impurities such as shredded paper, plastics, and fibers. It then enters a regulating tank, where water is stored and the inflow is adjusted to ensure a stable water supply to downstream equipment. The sewage is further treated in tanks PA1 (4), PO1 (5), PO2 (6), and a booster tank (7). Finally, it undergoes a biochemical coupling deep treatment process in tanks SA1 (8), SA2 (9), SB1 (10), SB2 (11), SB3 (12), and a sedimentation tank (14) to remove nitrogen and phosphorus. The treated water is then either discharged or reused.

[0041] Aerator 20 is responsible for supplying oxygen to aeration pipes 23 and 24 (P and B) and backflushing chambers 8 (SA1) and 9 (SA2) through backflushing pipe 30 (A).

[0042] The booster pump 27 is responsible for the power system of the sewage treatment.

[0043] P-AD technology (biochemical coupling deep processing)

[0044] The process consists of a pretreatment section, a core treatment unit consisting of a multi-element catalytic composite carrier, and an ultraviolet disinfection unit. Domestic sewage, after passing through the pretreatment section (biochemical treatment - biological packing), is pumped into SA1 compartment 8 by lift pump 27. It then flows through the multi-element catalytic composite carrier, overflow weir 37, and evenly distributed into SA2 compartment 9, SB1 compartment 10, SB2 compartment 11, and SB3 compartment 12 via distributed pipes 38. These compartments are filled with multi-element catalytic composite carriers, allowing for deep purification of the sewage as it flows through them.

[0045] Wastewater at the bottom of sedimentation tank 14 is returned to the bottom of SA1 tank 8 via circulation pump 18 to achieve recirculation. The bottom of SB1 tank 10, SB2 tank 11 and SB3 tank 12 is equipped with B aeration pipe 24, which provides an appropriate amount of oxygen. Through the biochemical coupling effect of the multi-element catalytic composite carrier, the wastewater is deeply treated.

[0046] This module consists of SA1 compartment 8, SA2 compartment 9, SB1 compartment 10, SB2 compartment 11, SB3 compartment 12, and a multi-component catalytic composite support. It generates strong oxygen through micro-region electrocatalysis on the support.

[0047] It can remove COD through chemical free radicals, electrocatalytic oxidation (advanced oxidation), catalytic oxidation-autotrophic denitrification coupled denitrification, and micro-electrolysis-catalytic oxidation-precipitation phosphorus removal. It can remove pollutants such as COD, ammonia nitrogen, total nitrogen, total phosphorus and SS without adding chemicals and achieve standard discharge. It can also be reused for greening, flushing and other purposes.

[0048] The control cabinet 19 outputs power supplies of different voltages to drive various electrical components, and the PLC program controls the equipment to work normally.

[0049] Domestic sewage first undergoes pretreatment, which intercepts and filters out impurities such as shredded paper, plastic, and fibers, and adjusts the sewage to meet the influent conditions for entering the main equipment.

[0050] Water inlet system

[0051] Wastewater is pumped through P inlet pipe 25, the first electromagnetic flow regulating valve group 15, and PA1 inlet pipe 26 into PA1 chamber 4 for wastewater treatment. Afterwards, it undergoes aerobic treatment in PO1 chamber 5 and PO2 chamber 6, and then converges in lift chamber 7. Lift pump 27, in conjunction with delivery branch pipe 28, the second electromagnetic flow regulating valve group 16, and inlet branch pipe 29, enters the advanced treatment SA1 chamber 8, and then from SA1 chamber 8 into SA2 chamber 9. Subsequently, it enters SB1 chamber 10, SB2 chamber 11, and SB3 chamber 12 in sequence. After thorough purification using different multi-element catalytic composite carriers in SA1 chamber 8, SA2 chamber 9, SB1 chamber 10, SB2 chamber 11, and SB3 chamber 12, it flows through the overflow pipe 31 of sedimentation chamber 14 and the first outlet branch pipe 32 into the ultraviolet disinfection machine 17 for sterilization. The treated water that meets standards is then discharged or reused.

[0052] Aeration system

[0053] A certain volume and pressure of gas generated by aerator 20 is controlled by normally open solenoid valve 21 to enter PA1 compartment 4, PO1 compartment 5, PO2 compartment 6, SB1 compartment 10, SB2 compartment 11, and SB3 compartment 12, thereby increasing oxygenation and accelerating the wastewater treatment reaction. A separate gas path, controlled by normally closed solenoid valve 22, opens periodically to enter SA1 compartment 8 and SA2 compartment 9, serving as a backflushing mechanism to increase the reaction surface area and improve reaction efficiency.

[0054] Reflux system

[0055] The wastewater is further treated and returned to the reflux chamber. Through the circulation pump 18, in conjunction with the A inlet pipe 34, the second outlet branch pipe 33, the SA1 chamber 8, SA2 chamber 9, SB1 chamber 10, SB2 chamber 11, SB3 chamber 12 and the sedimentation chamber 14, the wastewater is circulated. The treated water, N times the amount, is sent back to the SA1 chamber 8 for reprocessing, which increases the removal of total nitrogen.

[0056] The purpose of setting up PA1 compartment 4, PO1 compartment 5, and PO2 compartment 6 is to ensure the water intake conditions of SA1 compartment 8, SA2 compartment 9, SB1 compartment 10, SB2 compartment 11, and SB3 compartment 12.

[0057] Deep processing unit

[0058] It consists of SA1 compartment 8, SA2 compartment 9, SB1 compartment 10, SB2 compartment 11, and SB3 compartment 12, and contains different multi-element catalytic composite carriers. It is mainly used to remove COD, ammonia nitrogen, total nitrogen, total phosphorus and SS.

[0059] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
