Sewage treatment device suitable for rural areas in cold regions

Abstract

The invention provides a sewage treatment device applicable to rural areas in cold regions, which comprises a purification box, support frames are fixedly connected to two sides of the interior of the purification box, fitting blocks are fitted to the upper surfaces of the support frames, an impurity collection box is fitted to the top ends of the fitting blocks, and a funnel is fixedly connected to the bottom end of each fitting block. Sliding blocks are fixedly connected to the two sides of the impurity collecting box correspondingly, and first sliding grooves are formed in the outer portions of the sliding blocks in a sliding fit mode. The bottom end of the supporting frame and one end of the purifying box are fixedly connected with limiting blocks, second sliding grooves are formed in the limiting blocks in a sliding fit mode, and sliding blocks are arranged in the second sliding grooves in a sliding fit mode. By arranging a limiting block, a sliding block hanging plate and a hook, the filtering box is stably supported through the limiting block, the hook at the top end of the filtering box is connected with the hanging plate, the filtering position of the filtering box is stabilized, the hanging plate and the hook are detached by moving and lifting the filtering box, and maintenance is achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device suitable for rural areas in cold regions. Background technique [0002] Sewage (sewage treatment, wastewater treatment): The process of purifying sewage in order to make it meet the water quality requirements for discharge into a water body or for reuse. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering and other fields, and is increasingly entering the daily life of ordinary people. [0003] Most of the sewage treatment in the prior art uses a filter screen for filtration. When the impurities are smaller than the mesh number of the filter screen, the circulation of impurities will occur, and if the impurities are larger than the mesh number of the filter screen, the pipeline will be blocked, which is inconvenient to use. , ...
