Abstract

The invention relates to a vertical-type sewage treatment device, and belongs to the technical field of sewage biological treatment. The vertical-type sewage treatment device comprises a box body; inthe box body, from top to bottom, three stages of adsorption filtration zones, a plant treatment zone, and a deep purification water discharge zone are arranged successively; a bottom separating plateof each stage of adsorption filtration zone is designed to be inclined towards the water discharge zone; the three stages of adsorption filtration zones are arranged in a Z shaped manner, so that drop-aeration is realized; the circumferential wall is provided with air holes for ventilation; the first stage adsorption filtration is only loaded with a base filter material; the second stage adsorption filtration and the third stage adsorption filtration are loaded with the base filter material and an additive based on treatment requirements; shade-enduring plant is planted in the plant treatmentzone; the deep purification water discharge zone is provided with an ultraviolet germicidal lamp for further ensuring of the quality of discharged water. The vertical-type sewage treatment device issimple in technology, is convenient in maintenance, and is excellent in treatment effect, and is suitable to be used for treatment of domestic sewage or other low concentration sewage.

Description

technical field [0001] The invention relates to the field of water pollution control, in particular to a vertical sewage treatment device. Background technique [0002] The total amount of water resources in my country is abundant, but the per capita possession is insufficient, and a large amount of water resources are consumed in daily life, and a large amount of domestic sewage is produced at the same time. If it is not treated in a timely and effective manner, it will cause serious pollution to the environment. Effective treatment and utilization of domestic sewage will be of great significance to solve the problem of insufficient water resources in our country. Domestic sewage includes kitchen sewage, bathroom sewage, bath sewage and washing sewage, etc. Due to the different nature of incoming water, the pollutants contained in each water are different, so the treatment methods are different. [0003] The water quality of rural domestic sewage is characterized by high n...
