Problems solved by technology

There are mainly three shortcomings in the existing infiltration land treatment technology: (1) Since the adsorption saturation time of suspended solids, inorganic substances and other pollutants in different infiltration layers is inconsistent, when a certain effluent index exceeds the standard, it is necessary to Re-replacing all the filter layers of the system fails to make full use of the adsorption capacity of the soil infiltration layer to other pollutants, resulting in waste of functions and troublesome construction. The investment for each replacement is close to rebuilding a new system; (2) Reoxygenation is difficult, reducing the efficiency of sewage treatment; (3) The soil percolation layer is easily blocked, and the treatment system is prone to failure

Embodiment

[0030] An example of the present invention is as follows:

[0031] The impermeable tank 1 of the device is made of brick structure, with an effective height of 500mm, a width of 1000mm, and an effective length of 20000mm, of which the effective lengths of the four sections from water inlet to water outlet are 8000mm, 4000mm, 4000mm, 4000mm, and the sewage inlet liquid The water level is 100mm higher than the outlet liquid level. The water inlet and outlet pipes are made of PVC pipes with a diameter of 100mm. The plastic mesh bags used for packing the fillers in the functional section for removing organic matter and suspended matter have an aperture of 1mm, and are used for packing the other three functional profiles. The aperture of the mesh bag is 10mm, and the size of the plastic mesh bag is 400×800mm. The plastic mesh bags filled with fillers are laid in layers. A 60mm gravel layer is laid on the top of the device, and a 200mm undisturbed soil layer is laid on the gravel lay...

Abstract

An apparatus for deeply treating the sewage features that the percolation treatment of sewage is divided into four segments: the organic substance (BOD) and suspended substances (SS) removing segment, NH4-N removing segment, NO3-N removing segment and soluble phosphate removing segment.

Description

technical field [0001] The invention relates to a sewage advanced treatment device for horizontally and segmentally removing target pollutants, which enables the sewage to flow through several functional areas of the system in a horizontal direction to realize advanced treatment, and belongs to the technical field of water environment protection. Background technique [0002] Traditional land treatment technologies such as underground infiltration and rapid infiltration use the principles of physical adsorption, chemical adsorption, biodegradation and ecological effects of soil, plants and microorganisms. Pollution control is gradually being popularized and applied. [0003] However, in the prior art, the sewage is introduced into a tank so that the sewage flows vertically downward by gravity from top to bottom. For 500mm ~ 2000mm water collection pipe discharge. There are mainly three shortcomings in the existing infiltration land treatment technology: (1) Since the adsor...
