Rapid Construction Method for Filling Filter Material in Constructed Wetland Unit Pool

Abstract

The invention provides a rapid construction method for filling filter material in a constructed wetland unit pool. The constructed wetland unit pool is composed of a horizontal flow pool and an ascending flow pool, and the two are separated by a unit flower wall. During construction: the filter materials in the upflow pool and the horizontal flow pool are cross-filled in different areas. The filter material filling includes: layered and segmented filling forms. The types of filter materials include volcanic rock, crushed stone, zeolite, crushed Brick ceramsite, biological balls; the sub-regional cross construction, first fill the filter material outside the reserved opening, then fill the filter material from the side wall of the unit to the 2m position of the reserved opening, and then seal the wall of the reserved opening Blocking, and finally fill the remaining filter material. While reducing construction cost and improving construction efficiency, the present invention can effectively solve the problem of uneven thickness of layered filling, irregular dividing line of segmented filling, confusion of filter material and inconvenient construction machinery due to narrow roads outside the unit pool during filter material filling. Construction issues such as equipment access.

Description

technical field [0001] The invention relates to the construction field of a constructed wetland unit pool, in particular to a rapid construction method for filling filter material in a constructed wetland unit pool, which is a construction method for filter material layering and section filling. Background technique [0002] Constructed wetlands are artificially built into pools or trenches, and the bottom surface is laid with an anti-seepage water-proof layer and filled with a certain depth of soil or filler layer to form a ground that is artificially controlled and operated similar to swampland. According to the way of wastewater runoff, constructed wetlands can be Divided into three modes: surface flow wetlands, subsurface flow wetlands and vertical wetlands. In surface flow wetlands, wastewater flows on the surface of the filler, and the degradation of most organic matter is completed by microorganisms located in the biofilm at the base of plant stems submerged in wastew...
