Description

T-fill septic tank

technical field

The utility model belongs to the technical field of sewage treatment devices, in particular to a sewage treatment process in which a T-shaped fixed packing is installed inside a septic tank.

technical background

The utility model is suitable for sedimentation and digestion treatment of sewage pretreatment, and is especially applied to septic tanks as a technical measure for improving work efficiency. In the whole process of sewage treatment, it is realized by the pretreatment process and the follow-up process. The septic tank is the pretreatment process of domestic sewage. The main process function in the pretreatment stage is sedimentation. As a pretreatment process, the septic tank is one of the functions of depositing and decomposing organic matter, and has a certain anaerobic digestion function. Due to the low sedimentation and digestion efficiency of traditional septic tanks and the long residence time of sewage, generally the design sewage residence time of septic tanks is more than 12 hours, and the volume utilization rate of sewage treatment is low. According to the shallow sedimentation theory and the biological carrier function of the filler, the hydraulic radius can be reduced, the sedimentation efficiency and contact digestion capacity can be improved, and the sedimentation time can be shortened by installing the filler, which is an effective means to improve the working efficiency of the sedimentation tank. As the carrier of biological flora, the fixed plate packing itself has the function of contact digestion, and also has the ability to improve flocculation and sedimentation. The design of T-shaped packing units is conducive to production and installation. Through the above factors, the working efficiency of septic tanks can be realized. improvement.

Contents of the invention

The purpose of this utility model is to design a septic tank process with improved sedimentation and contact digestion capacity, which can achieve the sewage pretreatment effect of convenient process installation and improved efficiency and volume utilization.

The technical scheme of the utility model is realized by installing a three-dimensional T-shaped plate type packing block at the opening of the partition wall or partition of the two-compartment or three-compartment septic tank. This process can be built with bricks or reinforced concrete materials, and can also be used for septic tanks produced by glass fiber reinforced plastics or other reinforced plastics to build horizontal septic tanks. One end of the septic tank is the water inlet and the other end is the water outlet. The water inlet pipe and the water outlet pipe are provided, and the water inlet pipe and the water outlet pipe can be arranged in different directions according to the needs, and the internal space of the septic tank is separated by at least one partition wall or partition during the process from the water inlet end to the water outlet end. There is at least one water hole in the middle of the partition wall or the partition, and the sewage is pushed forward from the water inlet pipe end through the water hole. A T-shaped fixed packing unit body is socket-mounted from the water inlet direction in at least one partition wall of the septic tank. The packing unit is composed of a single piece of plastic or glass fiber reinforced plastic plate packing. The big end of the T-shaped packing plane can be rectangular, trapezoidal, semicircular, or other polygonal. The texture of the single packing can be multi-directional baffle, regular Or irregular bumpy texture. The bottom elevation of the septic tank inlet pipe is higher than that of the drain pipe, and the top of each space is provided with a cleaning inspection port. The lower part of the septic tank is a sedimentation area, the upper part of the partition wall is provided with air holes, and the top of the septic tank is provided with a ventilation pipe.

The utility model is a sewage pretreatment process, which is suitable for septic treatment of domestic sewage. The working mechanism of the utility model is mainly aimed at the pretreatment requirements of domestic sewage. According to the characteristics of low water quality requirements of the pretreatment process, it aims to improve efficiency, and realizes it through shallow flocculation and sedimentation and contact digestion of fillers. Plate packing such as multi-directional baffles has the function of shallow sedimentation, and also has the function of biological carrier packing, attaching and fixing anaerobic biofilm, on the one hand, it can digest sewage, and on the other hand, the biofilm can absorb particulate matter in sewage , to accelerate the precipitation. The use of T-shaped packing unit can achieve the purpose of simple socket installation. Generally, three-compartment septic tanks are used. When the scale of sewage treatment is small, two-compartment septic tanks can be selected. For three-compartment septic tanks, fillers are generally installed on one partition wall near the water outlet. If required, fillers can be installed on two partition walls. The utility model is beneficial in that the T-shaped fixed packing unit is used for installation, and the process efficiency of the septic tank can be improved by using a simple installation technology and process, thereby shortening the residence time of sewage, improving the volume utilization rate and sewage processing capacity, and save construction materials.
