Buried sanitary sewage processing device

Abstract

The embodiment of the invention discloses a buried sanitary sewage processing device. The device comprises a purification box, the purification box is connected with a deep purification cultivating tank through a pipeline, and partition plates are arranged in the purification box; the inside of the purification box is partitioned by the partition plates into an adjusting tank, a first filtering sedimentation tank, an anaerobic fermentation tank, a second filtering sedimentation tank and a disinfecting tank which are successively connected, the disinfecting tank is connected with the deep purification cultivating tank through a pipeline, the lower portion of the second filtering sedimentation tank is provided with a circulating pump, and the circulating pump is connected with the adjustingtank through a pipeline; a biological membrane plate is arranged in the anaerobic fermentation tank, the anaerobic fermentation tank is partitioned into upper and lower portions by the biological membrane plate, a partition plate is arranged on the upper area of the biological membrane plate, and the upper area of the biological membrane plate is partitioned into a liquid inlet area and a liquid outlet area through the partition plate; aeration devices are arranged on the lower area of the biological membrane plate and at the bottom of the adjusting tank. The device utilizes the principle of combining sedimentation and anaerobic fermentation for removing suspended organic matter in sanitary sewage and has the advantages that the sewage processing capacity is high, and the efficiency is high.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of sewage treatment, in particular to an underground domestic sewage processor. Background technique [0002] With the rapid development of the economy, a large number of people have poured into the city, and the city has been expanding from the center to the outside, while the construction of the corresponding sewage treatment plant is relatively backward. For the domestic sewage that cannot be treated by the sewage treatment plant, the relevant laws stipulate that independent sewage treatment facilities must be built to treat such domestic sewage and meet the corresponding environmental protection standards before discharge. There are many mature and feasible treatment technologies and processes for the treatment of domestic sewage at this stage, and each treatment technology has its scope of application and applicable conditions. For areas where land is scarce, beautiful environ...
