Embodiment 3

[0084] 1) Construction of an efficient and stable domestic sewage ecological treatment device;

[0085] 2) After the renovation of dry toilets in rural areas, the sewage from septic tanks undergoes simple physical settlement, and the supernatant flows into the water distribution main pipe, and then evenly enters the water distribution branch pipe;

[0086] 3) The sewage is evenly dripped and filtered to different substrate layers of the device through the outlet holes of the water distribution branch pipe, and the sewage is purified through the absorption, adsorption and degradation of the micro-ecological system composed of plants, substrate microorganisms, protozoa and metazoans;

[0087] 4) The purified sewage is collected by the water collecting pipe in the bottom groove and then discharged into the clean water pool for reuse.

[0088] The residence time of sewage in the ecological treatment device is 12h.

[0089] The hydraulic load inside the ecological treatment device...

Abstract

The invention relates to an efficient and stable domestic sewage ecological treatment device and operation method, belonging to the field of environmental engineering sewage treatment, including a soil layer, a water distribution layer, a magnetic layer, a gravel layer, a water collection layer from top to bottom, and a distribution layer Water collection system, water distribution and collection system includes water inlet pipe and water collection pipe. The water inlet pipe is divided into water inlet main pipe and several water inlet branch pipes. The water main pipe is vertically connected and located in the water distribution layer. The water inlet branch pipe is divided into upper and lower layers. The sewage enters the water inlet main pipe, the upper water inlet branch pipe, and the lower water inlet branch pipe in sequence. The water collection branch pipe and the water collection main pipe are vertically connected and located in the bottom groove. The lower water inlet branch pipe and the water collection branch pipe are respectively provided with a number of air intake pipes to communicate with the outside atmosphere. The treated sewage flows into the water collection main pipe from the water collection branch pipe and then discharged. The sewage is evenly distributed and the treatment efficiency is high.

Description

technical field [0001] The invention belongs to the field of environmental engineering sewage treatment, and in particular relates to an efficient and stable domestic sewage ecological treatment device and an operation method. Background technique [0002] In the process of building a new socialist countryside, in order to further improve the rural living environment, rural dry toilets have been transformed, but the treatment and disposal of septic tank effluent after transformation has become a major problem. The low treatment capacity of domestic sewage in rural areas of our country has led to rural domestic sewage becoming one of the important sources of surface water environmental pollution. In the current rural areas, the pipe network coverage is low, the sewage treatment facilities are not perfect, and the centralized domestic sewage treatment method cannot be applied to the current situation in rural areas. The use of decentralized domestic sewage treatment technology...
