Building sewage treatment and stereo-greening system

Abstract

Energy consumption in a large city is 75% total energy consumption of the world, and a greenhouse gas discharge amount is 80% total greenhouse gas discharge amount of the world. In China, the building gross area is more than 40 billion square meters and buildings having the area of 2 billion square meters are built each year and thus building energy-saving and low-carbon city transition development is extremely urgent and city space stereo-greening gets attention more and more. The invention discloses a building sewage treatment and stereo-greening system. The building sewage treatment and stereo-greening system comprises a sewage biogas energy utilization system, a sewage resource utilization system and a building roof greening system. Life sewage is fed into a fermentation tank [2] from a sewage discharge pipe [1], biogas is collected and used, and the biogas slurry goes through a water-pressure spacing pipe [7], a water collection tank [9] and a water pipe [10] and irrigates artificial soil layer vegetation [3] on a water proof layer [4] of a building roof tower [5]. The building sewage treatment and stereo-greening system is a simple and convenient building greening energy-saving ecological system, realizes transition of sewage into novel biogas energy and a sewage resource and is one of the cost-optimal building energy saving and emission reduction engineering projects. The building sewage treatment and stereo-greening system has the advantages of water saving, energy saving, economical efficiency and environmental friendliness.

Description

(1) Technical field [0001] The invention relates to sewage treatment in high-rise buildings and three-dimensional greening on roof terraces to utilize reclaimed water. It integrates building energy saving and greening, sewage treatment and utilization as a whole, and consists of sewage biogas energy utilization system, sewage resource utilization system and building In-building sewage treatment and three-dimensional greening system composed of roof greening system. (two), background technology [0002] In September 2011, the three-dimensional greening group of the China Urban Science Research Association and the Green Building and Energy Conservation Committee was established in Beijing, indicating that Chinese architecture is transforming towards the development of green buildings, and the transformation and development of building energy conservation and low-carbon cities is imminent. According to the "Economic Daily" report on January 29, 2012 entitled "Three-dimensional ...

AI Technical Summary

Problems solved by technology

So far, there is no more convenient, effective, and economical solution for recycling sewage resources in high-rise buildings; nor is there a more convenient, effective, and economical solution that can directly grow three-dimensional greening plants for high-rise buildings. Solutions that provide water and nutrients are needed; there is no example of biogas treatment of sewage in high-rise buildings
