Embodiment

[0041] The percolation area of ​​the device is 150m 2 , the sewage treatment capacity is 20t / d, the water distribution pipe is 350mm from the ground surface, and the water collection pipe is 1500mm from the ground surface. The infiltration layer is nocturnal soil in the Taihu Lake area with 20% cinder added. 120mm, the top surface of the functional layer is 750mm from the ground surface, the size of the profile unit is 300×300×120mm, the four-sided symmetrical perforation on the profile along the height direction is square, and the size of the hole is 200×60mm. The treated sewage is a rural domestic sewage in Yixing City in the Taihu Lake Basin. The SS, BOD, T-N, and T-P of the sewage entering the device are: 120-150mg / l, 100-140mg / l, 20-30mg / l, 2-3mg / l Left and right, after being treated by the above devices, the SS, BOD, NH in the water 4 + -N, T-N, T-P are respectively: 3-5mg / l, 4-8mg / l, 6-8mg / l, 0.02-0.01mg / l or so, and the effluent quality is better than the first-level...

Abstract

A waste water treatment equipment with the aerate layer of ammonia and phosphorus removal. The hollow material layer which have the function of ammonia and phosphrus removal divided the percolation fileration layer into aerobic layer and anaerobic layer. The waste water flow through the anaerobic layer from up to down to remove the SS, BOD, NH4+-N, T-P. The invention can remove the NH4+ and P efficiently and deal with the wastewater deeply.

Description

technical field [0001] The invention relates to a sewage advanced treatment device with an aeration layer for deammonization and dephosphorization, which can carry out intensive deamination and dephosphorization treatment of sewage, and belongs to the technical field of environmental protection water treatment. Background technique [0002] Non-point source pollution and water eutrophication have seriously reduced the water resource utilization value of lakes and reservoirs, which has become a prominent environmental and social problem at present. Nitrogen and phosphorus are the main limiting factors causing water eutrophication. When water bodies When the total phosphorus concentration is higher than 0.02mg / l or the total nitrogen concentration is higher than 0.2mg / l, algae may reproduce abnormally, resulting in eutrophication. How to control the key influencing factors of nitrogen and phosphorus that cause eutrophication of water bodies, effectively reduce the nitrogen and...
