Embodiment Construction

[0031] figure 1 It is a kind of sewage ecological treatment facility, which is composed of septic tank, hydrolytic acidification tank, buffer tank and soil infiltration system.

[0032] exist figure 1 In the process, the sewage first enters the septic tank, and the effective volume of the new septic tank is 0.75m 3 , The septic tank mainly plays the role of destroying the macromolecular chain of sewage, improving the biodegradability of wastewater, and the role of organic matter such as rotten feces.

[0033] The sewage treated by the septic tank enters the hydrolysis and acidification tank, and the residence time is controlled for 4 to 6 hours. The hydrolysis and acidification tank is divided into two compartments, and the effective height (depth) is generally between 2 and 2.5m. From the perspective of water distribution uniformity and economy Considering that the hydrolytic acidification tank adopts a circular design, with a reinforced concrete floor, brick walls, and wat...

Abstract

A disclosed soil percolation system applicable to sewage ecological processing is composed of a plant layer, a plantation soil layer, an artificial soil layer, a supporting layer, a sand filtering layer and an impervious layer from top to bottom; the plant layer is formed by combining plants with relatively developed roots; the plantation soil layer is composed of fertile cultivation soil and is embedded with crushed straws, and earthworm is introduced into the plantation soil layer; the artificial soil layer is formed by mixing 80% of sand clay and 20% of furnace slag; the plantation soil layer and the artificial soil layer are both provided with water distribution trenches in which water inlet pipes are spread; the supporting layer is composed of gravels with the diameter of 30 mm and is inside provided with a water collection pipe; the sand filtering layer is backfilled with grits; and the impervious layer is constructed by employing C25 plain concrete. The system employs a composite purification technology for processing domestic sewage by comprehensively utilizing the combined action of soil, straws, microbes and plants, especially earthworm is utilized for processing straws, and the purposes of changing waste into valuables and purifying environment are realized.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a soil infiltration system suitable for sewage ecological treatment. Background technique [0002] Soil infiltration treatment system is an artificially enhanced sewage ecological engineering treatment technology. It makes full use of the physical and chemical characteristics of soil animals, soil microorganisms, plant roots and soil that live in the soil below the surface to purify sewage. Small sewage land treatment system. Research on underground systems at home and abroad mainly focuses on filling media, pollutant purification mechanism, operation regulation, etc., but there is still a lack of unified understanding of key factors such as system structure, pollutant migration and transformation laws, microbiological characteristics, and removal of pathogenic microorganisms. However, there are still problems such as single structure, poor denitrification effect, unsta...
