Novel internal circulation sedimentation filter tank for farm sewage treatment

Abstract

The invention discloses a novel internal circulation sedimentation filter tank for farm sewage treatment. The novel internal circulation sedimentation filter tank comprises a sedimentation filter tankbody, a first honeycomb pipe layer, a filter tank liquid inlet pipe, a filter screen plate, a circulating device, a sludge scraping device, a sludge sedimentation hopper and a sludge discharge pump,a filter tank liquid inlet pipe communicated with the interior of the sedimentation filter tank body is arranged on the side edge of one side of the sedimentation filter tank body; the first honeycombpipe layer is transversely arranged in the middle in the sedimentation filter tank body; the first honeycomb pipe layer is formed by obliquely splicing and combining a plurality of honeycomb pipes; amud scraping device is arranged on the lower sides of the honeycomb pipe; a filter screen plate is obliquely arranged on the lower side of the mud scraping device; according to the invention, throughcooperation of the filter screen plate, a circulating device, and the mud scraping device which are arranged in a sedimentation tank, internal circulation filtration on sewage in the sedimentation tank is realized, filtered matters are collected, suspended matters and sediments in the sewage can be effectively filtered, the sewage separation quality of a farm is improved, and the sedimentation tank can realize internal circulation filtration.

Description

【Technical field】 [0001] The invention relates to the technical field of sewage treatment, in particular to the technical field of sedimentation tanks for sewage treatment in farms. 【Background technique】 [0002] At present, the most troublesome problem in the breeding industry is the treatment of sewage. The main method currently used for excrement is to collect dry excrement and make it into organic fertilizer for reasonable use. However, the excrement and the sewage after cleaning the farm cannot be effectively treated and utilized. The sewage is rich in nitrogen, phosphorus, organic matter, and high-suspended solids. If the farmers directly discharge these sewage into the river, it will seriously pollute the environment on the one hand, and on the other hand, the environmental protection department will also punish them. In severe cases, they may even close their doors. out of business. Therefore, how to solve these sewage has become an urgent problem for farmers to s...
