This utility model discloses a novel anaerobic water distribution pipe structure for wastewater treatment, relating to the field of anaerobic treatment technology. It includes a main pipe, which is rectangular and connected end-to-end. Flexible pipes are connected to both sides of the main pipe, with the lower ends of the flexible pipes extending into the water distribution pipe. The water distribution pipe is welded to the anaerobic tank. A butterfly valve is connected in series at the connection between the flexible pipe and the main pipe. In this utility model, the main pipe is rectangular overall, but the water flow inside is circular. The single-point flow rate and flow velocity of the circular water distribution are relatively small, resulting in a significantly less impact on the sludge layer at the bottom of the tank compared to centralized water distribution. This helps maintain the stability of the sludge bed, reduces sludge loss or floating, and ensures the activity and population balance of anaerobic microorganisms. When one shut-off valve is opened, water can flow from one side to the other for distribution; when both shut-off valves are opened, water can flow simultaneously from both sides towards the inner end, thus achieving a rapid and uniform water distribution effect.

This invention belongs to the field of wastewater treatment and resource utilization technology, and particularly relates to a system and method for low-energy anaerobic-gravity membrane wastewater resource utilization treatment. The system includes: a pretreatment unit, an anaerobic biofilm tank unit, a gas-liquid separation and flow stabilization unit, a gravity-driven membrane bioreactor unit, and a permeate reuse unit, all connected in series. The anaerobic biofilm tank unit is also connected to a biogas collection unit and a sludge treatment unit. After pretreatment, wastewater enters the anaerobic biofilm tank, where anaerobic microorganisms degrade organic pollutants and produce biogas. The anaerobic effluent, after gas-liquid separation and flow stabilization, enters the gravity-driven membrane bioreactor unit. Low-energy membrane separation is achieved by relying on the natural transmembrane pressure difference formed by the liquid level difference. The permeate is disinfected and reused, while the biogas and residual sludge are utilized for resource recovery. This invention eliminates the need for high-energy-consuming suction pumps and aeration systems, reducing operating energy consumption, and enables the resource utilization of biogas and residual sludge.

Typical kitchen trash cans have lids to prevent food waste odors from escaping. However, the sealing action of these lids actually activates anaerobic microorganisms that cause food waste odors, making the smell even stronger. [Solution] The trash can body is provided with an air inlet and an air outlet. The air inlet has a smaller opening area than the air outlet and is located at the bottom of the body. The air outlet is located in a different part from the air inlet and in an area where the air inside the body is discharged from above the air inlet. This allows the heat generated from food waste to be discharged to the outside of the trash can, preventing the high temperature and humidity environment that anaerobic microorganisms prefer.

Typical kitchen trash cans have lids to prevent food waste odors from escaping. However, the sealing action of these lids actually activates anaerobic microorganisms that cause food waste odors, making the smell even stronger. [Solution] By creating numerous holes in the lid of the trash can that are too small for pests to enter, it is possible to keep food waste constantly exposed to fresh air, preventing the activation of anaerobic microorganisms that cause odors. Furthermore, by providing air inlet and outlet holes in the body of the trash can, the heat generated from food waste is released to the outside of the trash can, preventing the high temperature and humidity environment that anaerobic microorganisms prefer, thus preventing their activation in a double way.
