Water-saving energy-saving utilizing system for improving septic tank

Abstract

Sewage of an urban septic tank can generate huge biogas new energy but unfortunately is not developed and used yet up to now. Metropolitan energy consumption accounts for 75% of the total energy consumption of the whole world, and the greenhouse gas emission accounts for 80% of the total greenhouse gas emission of the whole world. The existing urban septic tank cannot meet the social development need; a water-saving energy-saving utilizing system for improving the septic tank is provided, the basic principle of the water-saving energy-saving utilizing system is to improve an original septic tank, and after the sewage is biologically fermented to produce biogas, biogas new energy and a biogas slurry water resource are collected and utilized. The sewage is flushed into a fermentation tank of a biogas production system [2] capable of collecting and fermenting the sewage to generate biogas through a sewage discharge pipe [1], biogas is collected and utilized through a biogas energy collecting and utilizing system [3], and fermented biogas slurry sewage flows into and is stored in the original septic tank inside a biogas slurry sewage resource collecting and utilizing system [5] through a water pressure limit pipe [4]. Because biogas slurry is a precious organic fertilizer, tea growers, vegetable growers and fruit growers purchase the biogas slurry at high price, almost no biogas slurry is discharged from a raw sewage pipe network.

Description

(1) Technical field [0001] The invention relates to a building energy-saving and water-saving renovation, which converts sewage into biogas new energy and water resources, and collects and utilizes it, especially a septic tank renovation water-saving and energy-saving utilization system for converting existing septic tanks into biogas tanks . (two), background technology [0002] Decades ago, the Chinese government attached great importance to the development and utilization of biogas. Rural biogas was exhibited in the China Pavilion of the World Expo held in the United States as early as 1982. So far, the technology has been relatively mature, and has achieved considerable results, and has been promoted to a certain extent. However, in densely populated urban septic tanks, sewage can produce huge biogas new energy, which has not been developed and utilized so far. It is a pity that it is discharged into the atmosphere from the septic tanks downstairs and the sewage pipe ne...

Problems solved by technology

The current status quo is as follows: on the one hand, the growth of plants between urban and rural areas requires a lot of water and nutrients; What is worse is that septic tanks and pipe networks are often blocked, sewage flows across, and the smell is unpleasant, affecting the appearance of the city and environmental sanitation

In fact, so far there is no more convenient, effective, and economical solution for the reuse of sewage resources in buildings; nor is there a more convenient, effective, and economical solution that can directly provide green space around buildings. Plant growth on the need to provide water and nutrient solutions
