I. Product Features of Rural Domestic Wastewater Treatment Equipment
1. The equipment can be installed below the frozen layer or placed on the ground. The surface above the equipment can be used for landscaping or other purposes without the need for construction and heating/insulation.
2. The second-level biological contact oxidation process uses描流式生物摘要化 technology. It achieves treatment effects equivalent to mixed or secondary series-mixed biological contact oxidation systems, with smaller transmission results compared to activated sludge systems. It is effective in binding water quality with active quality and protein content, with resistance to medium load and moderate shock load.
Water quality is stable and does not cause sludge expansion. The pool utilizes new elastic three-dimensional packing material, which has a larger specific surface area, making it easier for microorganisms to attach and detach. Under the same material load conditions, it can improve the solubility of oxygen in the air within the water.
3. The biochemical edge uses the bio-contact oxidation method, with a relatively low volume load of its filling material. Microorganisms are in their own oxidation stage, resulting in less sludge production. It only requires draining the sludge once every 3 to 6 months (by using manure trucks for suction or dewatering sludge cakes for transportation).
4. The buried sewage treatment equipment in this area not only employs conventional high-altitude exhaust for odor control but also includes soil deodorization measures.
5. The entire equipment processing system is equipped with an automatic electrical control system. It operates independently and generally requires no dedicated management; only routine maintenance and care are needed at appropriate times.
The Myuan-VFS vacuum flushing system, with the aid of the vacuum system and control valves, can absorb an adequate amount of water and maintain it at a certain height. This generates sufficient potential energy. After the pool is emptied, the water in the sediment chamber is released, converting the potential energy into kinetic energy, creating a powerful flushing water flow. This flow carries the remaining sediments in the pool to the collection pit and discharges them to the wastewater treatment plant.

Automatic Diaphragm Valve
Manufactured from SUS304, it includes a large EDPM diaphragm valve, vacuum retention device, and vacuum release device. It is a component of the entire vacuum flushing system, connected to the vacuum negative pressure system via vacuum tubes and air supply tubes.

Features:
◆Even with light rainfall, it can still perform flushing functions.
◆Can also be designed with external water supply for flushing as needed.
The system's use is not restricted to the geometric shape of the water storage room.
Low power consumption.
◆Automatic operation, the system can also be upgraded for remote control.
◆ The pool is free of equipment requiring maintenance, offering excellent working health conditions.
Minimal maintenance (simply requires regular oil changes).
Vacuum Depressurization System
The power unit of the vacuum flushing system assembly, a complete set consisting of a single-stage scroll vacuum pump, vacuum valves, vacuum gauges, an intelligent control box, a vacuum tank, and corresponding pipeline valves. It can be started and stopped manually or automatically. Optional single/dual pump alternating operation mode.
Features:
◆ No underwater equipment or parts; maintenance is accessed within the reservoir.
◆Supply of additional water, utilizing stored rainwater (or mixed wastewater) for flushing.
◆High cleaning efficiency (up to 7 meters of water head in place energy).
◆ Superior flushing performance even in long or gently sloping channels.
