METHOD FOR ECOLOGIC CONFIGURATION OF OIL PRODUCTION HIGH-SALT WASTEWATER ARTIFICIAL WETLAND TO REALIZE UP-TO-STANDARD OPERATION IN WINTER

摘要

A method for ecologic configuration of an oil production wastewater artificial wetland to realize up-to-standard operation in winter. When artificial wetland is utilized to treat oil production high-salt wastewater, ecologic configuration of subsurface and surface flow artificial wetland is modified to realize up-to-standard operation in winter. Subsurface flow artificial wetland is composed of soil matrix, water distribution pipe disposed on bottom of soil matrix, wrapped with water-permeable nonwoven cloth and configured to deliver wastewater, and reeds with root systems growing on an inner side of wall of water distribution pipe, stems growing on outer side of wall of water distribution pipe and length being greater than thickness of soil matrix; and surface flow artificial wetland is composed of soil matrix, reeds growing on matrix, water, winter aquatic salt-resistant cold-liking plants, block-stocked fishes, shrimps, crabs, mussels, Mytilus edulis, oysters or clams and artificial sand dam.
