Bacteria filter for urban rainwater collecting

Abstract

The invention discloses a bacteria filter for urban rainwater collecting. A filtering medium layer is mounted in a bacteria filter body; a transition medium layer supporting the filtering medium layer is arranged under the filtering medium layer; a compost covering layer covers the upper surface of the filtering medium layer; plants are grown on the compost covering layer; a water drain pipe for draining treated rainwater is arranged at the lower part of the bacteria filter body; an overflow pipe enabling untreated rainwater to overflow is arranged at the upper part of the bacteria filter body; and a rainwater retention zone is arranged above the transition medium layer in the bacteria filter body. The bacteria filter is reasonable in structure, can treat and collect rainwater, provides a large amount of high-purity water sources to be selectively used in cities, and meanwhile, solves the urban environment problem caused by storms. Viewed from the ecology, the bacteria filter for urban rainwater collecting can serve as or replace existing urban greening well, and has the characteristics of environment friendliness and strong compatibility.

Description

technical field [0001] The invention relates to a biofilter used for rainwater treatment and collection. Background technique [0002] With the process of urbanization, industrial development, and population increase, our traditional water resources are being threatened step by step and becoming scarce. The urban water crisis has actually become an important obstacle to the development of our cities and the improvement of people's living standards. On the other hand, the global climate warms, the frequency of rainfall becomes smaller, but the amount of rainfall increases greatly. It caused serious waterlogging problems to the city. People living in modern cities and our city planners are all faced with the above two dilemmas. [0003] In the recent stage, the concept of urban water-sensitive design has quietly emerged, which advocates the integration of urban water cycle management into urban design and planning. The urban water cycle includes: urban drinking water, urba...
