technical field

The utility model relates to a sewage anaerobic reactor embedded with a fiber filler biofilm.

Background technique

With the growth of economy and population, the discharge of sewage is increasing day by day. If it is not treated properly, it will lead to a series of problems such as the environment of the water basin and the health of residents. At present, the methods of sewage treatment mainly include physical and chemical processes and biological treatment processes. However, there are problems such as high cost of treatment, difficulty in guaranteeing the effect, and unstable operation in the treatment of sewage by physical and chemical processes. Therefore, the biological treatment method has attracted the attention of many researchers, and the anaerobic process has attracted widespread attention due to its advantages of low energy consumption, high load, and less residual sludge. The up-flow anaerobic sludge blanket reactor (UASB) is a typical representative of a new generation of high-efficiency anaerobic reactors. It has been used in the treatment of various organic sewage in recent years, showing Good handling effect. Using UASB anaerobic reactor to treat sewage can not only achieve good treatment effect, but also produce renewable clean energy hydrogen or biogas. However, the UASB anaerobic digestion hydrogen production process has problems such as long start-up period, harsh environmental conditions for anaerobic microorganisms in the reactor, sensitivity to water quality and load changes, poor system stability, low organic matter degradation rate, and poor hydrogen production effect. . In order to achieve efficient sewage treatment effect, it is necessary to improve the traditional UASB reactor and adopt additional means to form a new UASB reactor to achieve better removal efficiency.

The existence of construction area can effectively screen and retain sludge, ensure sufficient biomass in the system, degrade organic matter in wastewater, improve sewage treatment efficiency, make sludge not easy to lose, and sludge has good sedimentation performance and is easy to form particles sludge, and increases the contact area between sewage and microorganisms, thereby increasing the hydraulic load and volume load of the reactor, thereby improving the treatment efficiency.

2. In the utility model, the solid fiber ropes are respectively penetrated through the round holes of a group of solid fiber packing Pall rings, penetrate each solid fiber packing Pall ring hole, and then perform knotting treatment, the solid fiber packing Pall rings The rings pass through the sockets in the fiber packing mounting bulkhead, are knuckled on top of the sockets, and then a set of solid fiber packing Pall rings will be installed, each with solid fiber The fiber filler of the filler installs the annular embedded plate of the partition plate into the annular tank, and a set of solid fiber filler Pall rings are set in the sludge suspension layer area, so that microorganisms grow and accumulate on the solid fiber filler to form a biofilm.

3. The solid fiber packing Pall ring of the utility model adds a small-diameter circular rib between the traditional Pall rings, and between the large-diameter circular rib and the small-diameter circular rib, and between the small-diameter circular rib and the central circular rib They are connected by a group of reinforcing ribs, which increases the strength of the connection between the large-diameter circular ribs, small-diameter circular ribs and central circular ribs, and effectively reduces the long-term use of large-diameter circular ribs and central circular ribs. The possibility of moderate deformation greatly improves the strength of the solid fiber packing Pall ring, especially the strength between the large-diameter circular rib and the central circular rib, which can meet long-term use without deformation.
