Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] as attached Figures 1 to 10 Described a kind of sewage filtering device comprises solid filtering device 1, grease filtering device 2 and sludge filtering device 3; Said solid filtering device 1 is used for filtering plastic products floating in sewage, and these plastic products cannot be recycled again, The grease filtering device is used to remove most of the grease in the sewage. If the grease content in the sewage is too high, the utilization rate will be low. The sludge filtering device 3 is used to filter most of the silt in the sewage.

[0033] The solid filtering device 1, the grease filtering device 2 and the sludge filtering device 3 are connected in sequence through pipelines.

[0034] Described grease filter device 2 comprises grease filter box 203, bottom plate 204, cover plate 202 and scraper 205, and the bottom of described grease filter box is...

Abstract

The invention discloses a sewage filtering device and a sewage filtering method. The sewage filtering device comprises a solid filtering device, a grease filtering device and a sludge filtering device, wherein the solid filtering device, the grease filtering device and the sludge filtering device are sequentially connected; a bubble generator is arranged at the bottom of the grease filtering device; the bubble generator is connected with an air flotation machine; a cover plate is arranged at the top of the grease filtering device; an oleophylic fiber is arranged at the bottom of the cover plate in a covering manner; organic matters filtered by the grease filtering device and sludge filtered by the sludge filtering device are sufficiently mixed and stirred and are fed into a fermentation tank for fermentation. By adopting the sewage filtering device and the sewage filtering method disclosed by the invention, the filtering effect of rural sewage can be improved, and reuse of sewage can be promoted.

Description

technical field [0001] The invention provides sewage treatment equipment, and in particular relates to a filtering device and a sewage filtering method suitable for treating rural sewage. Background technique [0002] With the development of industry and the improvement of people's living standards, the amount of sewage generated in both urban and rural areas is increasing year by year. The main components of rural sewage and urban sewage are different. Urban sewage not only includes domestic sewage produced by urban residents, but also industrial wastewater produced by factories. The composition is relatively complex, while rural sewage is mainly composed of domestic sewage and rainwater. There are sewage treatment plants in every city to treat the sewage produced, but there are few treatment devices for the sewage produced in rural areas. In addition to simple components, rural sewage also has the characteristics of high availability. Due to the lack of hardening of the ...
