Abstract

The invention relates to the technical field of rural sewage treatment equipment, in particular to a kitchen sewage treatment device. The device includes a sewage collection well and a reaction pool arranged around the sewage collection well. The bottom of the sewage collection well and the side walls of the sewage collection well are all impermeable structures. The reaction pool is sequentially provided with fine sand layers, The geotextile and gravel layer, and the fine sand layer are planted with moisture-resistant herb plants. The bottom of the reaction tank and the side wall of the reaction tank are all impermeable structures; The side wall and the position of the fine sand layer are provided with a second permeable hole. The second permeable hole is higher than the first permeable hole, prolonging the residence time of the kitchen sewage in the reaction tank, and enhancing the fine sand and moisture-resistant herb root system against the sewage. The adsorption and absorption effect of pollutants can denitrify as much sewage as possible, reduce the nitrate nitrogen content of sewage, realize centralized and effective treatment of kitchen sewage, and reduce the pollution of kitchen sewage to the environment.

Description

technical field [0001] The invention relates to the technical field of rural sewage treatment equipment, in particular to a kitchen sewage treatment device. Background technique [0002] At present, with the development of rural tourism and the construction of new countryside, the discharge of kitchen sewage is also increasing rapidly while rural life is convenient. There is a lot of oil pollution in the medium, and long-term discharge will cause oil pollution to accumulate on the land surface, preventing the soil from transforming and decomposing sewage, and destroying the balanced ecological environment in rural areas. Moreover, the infrastructure and sewage treatment facilities in rural areas are not as perfect as those in cities. It is also impossible to cover the sewage pipes, so it is difficult to realize the centralized treatment of sewage. Therefore, the treatment of kitchen sewage at this stage has become an urgent problem in rural development. Contents of the inv...
