A floating sewage purification device

Abstract

A floatable sewage purification device comprises a water collecting tank and a water tank for sewage treatment, wherein a sealing chamber is formed in the periphery of the water tank, and a water inlet area, a first decontamination area, a second decontamination area, a water outlet area and a sedimentation area are arranged in the water tank; the water inlet area is located above the first decontamination area, the water outlet area is located above the second decontamination area, and a first baffle plate is arranged between one side formed by the water inlet area and the first decontamination area and the other side formed by the second decontamination area; the sedimentation area is located below the first decontamination area and the second decontamination area, and a water permeable support plate is arranged between the sedimentation area and the bottom of the first decontamination area and the second decontamination area; a plurality of pieces of oil absorption felt and elastic materials are arranged in the first decontamination area, one end of each piece of oil absorption felt is fixed on a cross beam, and each piece of oil absorption felt extends in the depth direction of the water tank; an aerating apparatus is arranged in the sedimentation area; a biological ceramsite layer and a lava rock packing layer are arranged in the second decontamination area from top to bottom, and multiple second baffle plates in parallel arrangement are arranged in the second decontamination area from left to right; a plurality of overflow holes distributed in the circumferential direction of the water tank are formed in the upper part of the water outlet area.

Description

technical field [0001] The invention relates to the technical field of sewage purification, in particular to a floating sewage purification device. Background technique [0002] Urban water environment and water ecology are important issues related to people's livelihood. In recent years, there has been an upsurge of urban river management all over the country. Due to the weak municipal infrastructure in some areas, the sewage pipe network is not fully covered, or the rain and sewage diversion treatment is not done well, resulting in a large amount of domestic sewage being discharged into urban rivers. Especially in some old residential areas near the river, the original sewer pipe network has been in disrepair for a long time, but due to the small space of urban roads, new sewage interception and collection projects cannot be carried out. Residents privately lay pipes to discharge domestic sewage into the river for the convenience of drainage. Domestic sewage is rich in o...

Problems solved by technology

Due to the weak municipal infrastructure in some areas, the sewage pipe network is not fully covered, or the rain and sewage diversion treatment is not done well, resulting in a large amount of domestic sewage being discharged into urban rivers

Especially in some old residential areas near the river, the original sewer pipe network has been in disrepair for a long time, but due to the small space of urban roads, new sewage interception and collection projects cannot be carried out. Residents privately lay pipes to discharge domestic sewage into the river for the convenience of drainage. Domestic sewage is rich in organic matter, nitrogen, phosphorus and oil, causing eutrophication of the surrounding river water, algal blooms, and finally a black and odorous state, seriously affecting the lives of residents and the landscape of the city
