Embodiment Construction
[0037] A kind of novel water pressure type strengthened biological septic tank of the present invention, with reference to figure 1 , figure 2 with image 3 , the treatment device mainly includes a solid manure feed port (1), a liquid manure feed port (2), a three-format septic tank (6, 7, 8), a water outlet well (9), an air storage room (17), Gas pipeline (5). The solid feces of the present invention enter the first septic tank (6) from the solid feces feed port (1) for fermentation, and the generated biogas is collected in the gas storage chamber (17) and used by residents through the gas pipeline (5). The liquid feces feeding port (2) enters the second septic tank (7), and the influent water with a low C / N ratio is conducive to the enrichment of anammox bacteria and denitrification. The first septic tank (6) and the second septic tank (7) are connected through the first water outlet (11), and the second septic tank (7) and the third septic tank (8) are connected through...

The invention relates to the technical fields of rural domestic sewage bio-treatment and sewage recycle, and especially relates to a novel hydraulic reinforced biological digestion tank. The novel hydraulic reinforced biological digestion tank is characterized in that the novel hydraulic reinforced biological digestion tank is composed of a three-grid digestion tank, two feed inlets and a water outlet well. Solid night soil enters a first-grid digestion tank (6) from a solid night soil inlet (1) for fermenting, and generated biogas is collected in a gas storage chamber (17) and is provided for residents to use through a gas convey pipeline (5). Liquid night soil enters a second-grid digestion tank (7) from a liquid night soil inlet (2). A fixed soft filler (10) is arranged in a third-grid digestion tank (8). A bent tube water outlet (13) is arranged in the water outlet well (9), and also is an overflow port, so the safety coefficient is improved. The novel hydraulic reinforced biological digestion tank has the advantages of reasonable structure, good gas production effect, no gas leakage, high safety coefficient, low concentration of suspension matters in outlet water, high evolution efficiency, and low investment cost.
Description
technical field [0001] The invention relates to the technical field of biological treatment of rural domestic sewage and the utilization of sewage resources, in particular to a novel water pressure enhanced biological septic tank. Background technique [0002] In recent years, my country's domestic sewage treatment plants have been continuously built, but they are mainly concentrated in cities, and rural domestic sewage has not been treated. At present, there are two main ways to treat rural domestic sewage: one is to incorporate domestic sewage into the municipal pipe network; the other is to establish on-site sewage treatment facilities. In densely populated urban areas, it is undoubtedly the right choice to increase the collection coverage of the pipe network and improve the centralized sewage treatment capacity. However, in the outer suburbs of the city and the vast rural areas, the centralized pipe network cannot be reached. The transportation and operation costs of se...
