Description

Technical Field

[0001] The utility model belongs to the field of sewage treatment equipment, and specifically relates to MBBR sewage integrated treatment equipment for flood-prone areas. Background Art

[0002] MBBR (Moving Bed Biofilm Reactor) sewage treatment device is a device that increases the biomass and biological species in the sewage treatment device by adding a certain amount of suspended carriers to the sewage treatment device, thereby improving the sewage treatment efficiency.

[0003] In recent years, with the continuous development of cities, many areas that were originally prone to flooding have also been utilized. As human activities in these flood-prone areas have become increasingly frequent and the concept of environmental protection has become increasingly popular, the problem of sewage treatment in flood-prone areas has gradually emerged. Many toilets in tourist areas and tidal flats need to be equipped with integrated sewage treatment facilities to treat sewage and then discharge it in compliance with standards. However, low-lying areas are often below the flood control level of once in five years or even lower, causing the fully buried sewage treatment facilities to be frequently soaked by floods, impacting the microorganisms in the MBBR sewage treatment device, damaging the automatic control and electrical equipment, and causing the treatment device to be paralyzed, resulting in economic losses and immeasurable environmental pollution.

[0004] In order to solve the above problems, we designed an MBBR integrated sewage treatment equipment for flood-prone areas. Utility Model Content

[0028] In this embodiment, if Figures 1 to 5As shown, a gas exchange box 3 is arranged on the top of the regulating tank 11, the sludge tank 12, the anaerobic tank 21, the anoxic tank 22, the MBBR tank 23, the sedimentation tank 24, the sand filter tank 25 and the equipment room 26. The ventilation pipe 4 is arranged on the gas exchange box 3. An exhaust device (not shown in the figure) is arranged in the gas exchange box 3. The exhaust device is a device such as an exhaust fan or an air pump to guide the flow of the air, so as to form an oxygen-rich or oxygen-deficient environment in the first box 1 and the second box 2 according to the needs of the microorganisms.

[0029] In this embodiment, if Figures 1 to 5 As shown, the anaerobic tank 21 and the anoxic tank 22 are both provided with fixed fillers 211; the bottom of the MBBR tank 23 is provided with an aeration plate 232, and the MBBR tank 23 is also provided with floating fillers 231; the sedimentation tank 24 is provided with an air stripping device 241; the sand filter 25 is provided with a sand filter 251; the equipment room 26 is provided with a buffer box 261 and a delivery pump 262, the inlet end of the buffer box 261 is connected to the municipal water, the outlet end of the buffer box 261 is connected to the anaerobic tank 21, and the delivery pump 262 is used to deliver the municipal water in the buffer box 261. Specifically, multiple groups of delivery pumps 262 are provided in the equipment room 26, some of which deliver relatively clean municipal water to the anaerobic tank 21 through a delivery pipe 263 for treatment; other delivery pumps 262 can be used to deliver the water that meets the discharge standards after being treated in the sand filter 25 to the outside for discharge. At the same time, an electric control cabinet 264 is also provided in the equipment room 26, and the electric control cabinet 264 is used to control the delivery pump 262 and the exhaust device.
