Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment, specifically relating to a mobile packing wastewater treatment device containing a mud-water separation device. Background Technology

[0002] Moving bed biofilm reactors (MBBRs), also known as suspended moving bed reactors, are a type of composite biofilm reactor. Their main principle involves directly adding suspended media with a density close to water into the aeration tank as a carrier for microbial growth and attachment. The floating carrier moves freely within the reactor due to the swirling and tumbling action of the mixed liquor. MBBRs have attracted considerable attention due to their advantages such as large biomass, strong resistance to shock loads, high treatment capacity, low energy consumption, and simple maintenance. However, although MBBRs are widely used in wastewater treatment, they suffer from problems such as poor sludge-water separation. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned technical problems by providing a mobile packing wastewater treatment device with mud-water separation.

[0004] This utility model discloses a mobile packing wastewater treatment device with mud-water separation, which includes a tank, a first biochemical reaction zone, a second biochemical reaction zone, a mud-water separation zone, and a water storage and disinfection zone.

[0005] The tank is sequentially configured with a first biochemical reaction zone, a second biochemical reaction zone, a mud-water separation zone, and a water storage and disinfection zone. The top of the first biochemical reaction zone has a wastewater inlet. A perforated partition separates the first biochemical reaction zone into two areas. The top of the perforated partition is connected to the inner wall of the top of the tank, while the bottom has a gap with the inner wall of the bottom of the tank, serving as a first flow channel. The second biochemical reaction zone is separated from the mud-water separation zone by a second partition, and a gap is left between the second partition and the inner wall of the top of the tank, serving as a second flow channel.

[0006] The second biochemical reaction zone includes a meandering area, which is composed of a first baffle plate, a second baffle plate (first arc-shaped plate, second arc-shaped plate), and a vertical baffle plate. There are two first baffle plates arranged horizontally parallel to each other. One end face of each first baffle plate is fixed to a first arc-shaped plate, and the outer wall of the first arc-shaped plate is connected to a second partition plate. One end face of the vertical baffle plate is connected to the top of the inner wall of the tank, and the other end face is connected to one end face of the second arc-shaped plate. The other end face of the second arc-shaped plate is connected to the end face of the second arc-shaped plate placed horizontally between the two first baffle plates. A water channel is formed between the second arc-shaped plate, the vertical baffle plate, and the second partition plate. A meandering channel is formed between the first baffle plate, the second baffle plate (first arc-shaped plate, second arc-shaped plate), and the vertical baffle plate. Both the first and second baffle plates are provided with concave through holes.

[0007] The bottom of the second biochemical reaction zone is equipped with a sludge discharge pump, which is connected to the upper part of the sludge-water separation zone through a pipeline; the top of the sludge-water separation zone is equipped with a water outlet weir, and the outlet of the water outlet weir is connected to the water storage and disinfection zone.

[0008] The first and second biochemical reaction zones are filled with movable spherical packing materials.

[0009] This utility model has the following beneficial effects:

[0010] This invention, through its meandering zone and perforated baffles, allows sludge to flow alongside the wastewater, effectively dispersing it and preventing excessive aggregation. This facilitates rapid separation in the subsequent sludge-water separation zone, improving separation efficiency. Furthermore, the concave perforations in the meandering zone disturb the water, creating smaller aerobic granular sludge particles, which are more beneficial for aerobic bacteria utilization, thus enhancing treatment effectiveness. This device improves sludge-water separation and increases sludge utilization. Attached Figure Description

[0014] The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0015] Specific implementation method one: Combining Figure 1 and 2 This embodiment describes a mobile packing wastewater treatment device with sludge-water separation, which includes a tank 1, a first biochemical reaction zone 2, a second biochemical reaction zone 3, a sludge-water separation zone 4, and a water storage and disinfection zone 5.

[0017] The second biochemical reaction zone 3 is provided with a detour zone 11, which is composed of a first baffle plate 111, a second baffle plate 112, a first arc-shaped plate 113, a second arc-shaped plate 114, and a vertical baffle 115. There are two first baffle plates 111 arranged horizontally parallel to each other. One end face of each first baffle plate 111 is fixed to the first arc-shaped plate 113, and the outer wall of the first arc-shaped plate 113 is connected to the second partition plate 7. One end face of the vertical baffle 115 is connected to the top of the inner wall of the housing 1, and the other end face is connected to the second arc-shaped plate 114. One end face of the first arc plate 114 is connected to the second arc plate 114, and the other end face of the second arc plate 114 is connected to the end face of the second arc plate 114 placed horizontally between the two first baffle plates 111; a water channel is formed between the second arc plate 114, the vertical baffle plate 115 and the second partition plate 7; a meandering channel is formed between the first baffle plate 111, the second baffle plate 112, the first arc plate 113, the second arc plate 114 and the vertical baffle plate 115; both the first baffle plate 111 and the second baffle plate 112 are provided with concave through holes 1111;

[0018] The bottom of the second biochemical reaction zone 3 is equipped with a sludge discharge pump, which is connected to the upper part of the mud-water separation zone 4 through a pipeline; the top of the mud-water separation zone 4 is equipped with a water outlet weir 12, and the outlet of the water outlet weir 12 is connected to the water storage and disinfection zone 5.

[0019] The first biochemical reaction zone 2 and the second biochemical reaction zone 3 are filled with movable spherical fillers 13.

[0020] The mobile packing wastewater treatment device with mud-water separation in this embodiment is used as follows:

[0021] Wastewater to be treated is injected through wastewater inlet 21, and the installed screen 15 disperses the sludge. Microorganisms in the first biochemical reaction zone 2 undergo microbial treatment under aeration. This zone is divided into two parts by a perforated baffle 6. Some wastewater and sludge can pass directly through the perforations of the baffle 6. The inner diameter of the perforations on the side of the baffle 6 facing the second biochemical reaction zone 3 is larger than that on the side facing the first biochemical reaction zone 2. This design allows wastewater and sludge to enter through small holes and exit through large holes, which helps to accelerate the flow rate of wastewater near the baffle 6, disperses the sludge into smaller particles, and promotes microbial attachment. Entering the meandering zone of the second biochemical reaction zone 3, the meandering channels facilitate the aggregation of sludge and wastewater, providing more favorable conditions for subsequent sludge separation and preventing sludge and moving packing material from accumulating at the bottom of the reaction zone, thus improving utilization. The recessed perforations disturb the wastewater, causing the sludge flocs to continuously tumble and form smaller-diameter aerobic granular sludge.
