Household miniature integrated device for sewage treatment

Abstract

The invention relates to a household miniature integrated device for sewage treatment, and belongs to the field of sewage treatment. The device comprises a wetland bed divided into an upper part and a lower part, and a bracket under the wetland bed; the upper part of the wetland bed is provided with a granule filler; and the lower part of the wetland bed is provided with a fibrous filler; the upper part and the lower part are separated by a stainless steel frame; side walls of the wetland bed are respectively penetrated with an inlet pipe, an outlet pipe, and an aeration pipe; the wetland bed bottom is provided with a drain valve; sand or soil is filled on the particle filter and the outlet pipe, and planted with wetland plants; and a ventilation tube is inserted into the particle filler. The integrated device provided by the invention can be used for treatment of household sewage in rural areas, and the effluent can be directly discharged into a river. The size of the device can be changed according to the designed amount of inlet water; and the device is suitable for household sewage treatment for relatively dispersed single family or several families in rural areas, and has the characteristics of easy operation and maintenance, and good and stable outlet water quality.

Description

technical field [0001] The invention relates to a small household sewage treatment integrated equipment, which belongs to the field of sewage treatment. Background technique [0002] The distribution of rural households in my country is relatively scattered, and there is no centralized underground sewage system. Most of them are sewage facilities for single households, or they are directly discharged after any treatment. As a result, the water pollution in rural areas of our country is becoming more and more serious, which affects the economy. The stable development of society has also caused great harm to the health of the people. [0003] Most of the rural households in my country are relatively scattered, and generally lack a unified drainage system. It is difficult to collect domestic sewage from each household for unified treatment and discharge. A small and efficient sewage treatment equipment can be designed to realize the sewage treatment of each household. It has th...

Problems solved by technology

[0004] The removal of organic matter and nitrogen and phosphorus by biological methods mainly depends on the action of microorganisms, and temperature has a great influence on the activity of microorganisms. It is difficult for existing technologies to overcome the problem of poor effluent quality due to the decrease in microbial activity in winter at low temperatures

At the same time, due to the use of a single particle filler for adsorption, the specific surface area of ​​the particle filler is limited, which may easily cause the adsorption saturation of the filler, and the operation effect is unstable after saturation, and the desorption is difficult.
