Abstract

The invention discloses an intensive device for treating rural domestic sewage and a construction method thereof and relates to the field of sewage treatment. The intensive device comprises a plurality of sewage collecting pipes; an anaerobic digestion system aerobiotic digestion pool and an ecological purification system which are sequentially connected; one ends of the sewage collecting pipes are connected with a household water-consumption outlet and the other ends are connected with the anaerobic digestion system; the anaerobic digestion system comprises a first stage anaerobic digestion pool, a second stage anaerobic digestion pool and a third stage anaerobic digestion pool which are sequentially connected; the volume computational formulas of the first stage anaerobic digestion pool, the second stage anaerobic digestion pool, the third stage anaerobic digestion pool and the aerobiotic digestion pool are: V=aNqt / (24*2000), wherein N is the serviced population size, a is the sewage generation coefficient of 0.7-0.9, q is the water consumption per capita of 80-120 L / d, and t is the retention time of the water in the corresponding digestion pool. The intensive device is small in occupied space and low in cost.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an intensive device for treating rural domestic sewage and a construction method thereof. Background technique [0002] With the development of the rural economy and the continuous advancement of urbanization, the discharge of pesticide and fertilizer residues in rural farming and aquaculture sewage has increased sharply, causing serious pollution to natural water bodies and soil. It is discharged into rivers and lakes, causing serious water and soil pollution. After the water and soil are polluted, harmful compounds, heavy metals and other pollutants enter the human body through the food chain, leading to a sharp increase in the number of cancer patients in rural areas and seriously damaging the health of the rural population. [0003] The United States, Japan and other developed countries have accumulated rich experience in the treatment of rural domestic sewage, mainly in the i...
