Background technology:
Subsurface infiltration is a kind of integrated anaerobism, aerobic treatment process and the ecological wastewater processing technology that forms.Its ultimate principle is: sewage after deposition, hydrolysis etc. are handled, is distributed in the water spraying pipe sewage smooth outflow from water spraying pipe in preprocessing process; Infiltrate aerobic filtering layer; Then diffusion motion under the effect of soil capillary power and gravity fully contacts with soil, through the combined action of soil-mikrobe-botanical system; Water pollutant obtains physical sepn, chemisorption and biological degradation, and water purification is collected through header.
Subsurface infiltration treatment process initial cost is low, management is simple.But, because water spraying pipe adopts equidistant cloth hole usually, cause aproll inhomogeneous, the water supersaturation takes place in the local soil layer, the pollution load overload has greatly influenced sewage treatment effect.
Summary of the invention:
The object of the present invention is to provide a kind of bore distribution method of subsurface infiltration sewage dispersion pipe, this method has the homogeneity that improves aproll, avoid producing the supersaturation of local soil layer water, prevent the pollution load overload and improve the characteristics of wastewater treatment efficiency.
A kind of bore distribution method of subsurface infiltration sewage dispersion pipe is:
1, water spraying pipe is a PVC material straight tube, length 12-18 rice, and inner diameter 60-80 millimeter, water spraying pipe water-in one end opening, the other end is with PVC plate welded closure.
2, being starting point with water spraying pipe water-in one end, on the tube wall of preceding 4-6 rice, is 8 millimeters aperture according to spacing 8-10 centimetre of even drill diameter.On the same circular section of water spraying pipe, bore 3 apertures, the arrangement mode of 3 apertures is on the same circular section: get 90 degree covering of the fans of circular section, 1 aperture is respectively bored at covering of the fan circular arc two ends, and 1 aperture bores in center of arc.
3, be starting point with water spraying pipe water-in one end; On the tube wall of back 8-12 rice; According to spacing 6-8 centimetre of even drill diameter is 8 millimeters aperture, on the same circular section of water spraying pipe, bores 3 apertures, and the arrangement mode of 3 apertures is on the same circular section: the 90 degree covering of the fans of getting the circular section; 1 aperture is respectively bored at covering of the fan circular arc two ends, and 1 aperture bores in center of arc.
4, with the water spraying pipe of boring, be embedded in the sandy soil layer 0.5 meter of buried depth according to center of arc's aperture mode level vertically downward.
5, inject sewage continuously at the water spraying pipe water-in, analyze effluent quality, the monitoring aquifer yield.
The present invention has following advantage:
1,, improved the homogeneity of aproll through inhomogeneous cloth hole design to water spraying pipe.
2, equal aperture is adopted in the design of cloth hole, and non-isometric method has been avoided the water supersaturation takes place in the local soil layer, and pollution load overload etc. is unfavorable for the problem of WWT, has improved wastewater treatment efficiency.
