ECOLOGICAL SEWAGE WATER TREATMENT SYSTEM

摘要

PURPOSE: An ecological water treating system is provided to maximize the natural purifying capability of the system and to minimize the area required for installing the system. CONSTITUTION: An artificial wetland(2) includes a raw water tank, an ecological contacting bath(6), an ecological precipitating and filtering bath(9), and an underground flow wetland(26). The raw water tank stores contaminated water and sewage. The ecological contacting bath is composed of an aerating tube(8), string microorganism media(10), and an artificial plant island(14) and treats the organic materials of the contaminated water and the sewage. The ecological precipitating bath eliminates the organic materials based on a contact media which is the root of aquatic plants(18). The underground flow wetland implements an absorbing process, a filtering process, and a decomposing process with respect to the contaminated water and the sewage.
