Abstract

The utility model discloses a building waste water secondary utilization system, which is composed of a building sewer pipe network. A water storage tank is arranged in the toilet of the building. The water storage tank is connected with the water supply pipeline of the toilet water tank from the bottom with the water storage tank sewer pipe behind the toilet water tank water supply pipe valve, and the water storage tank sewer pipe valve is arranged on the water storage tank sewer pipe, and the toilet under the toilet of each floor The water pipe is directly connected with the building sewer pipe. It is a building waste water secondary utilization system that can use part of the domestic waste water for toilet flushing water in the lower buildings without increasing any treatment costs.

Description

Building wastewater secondary utilization system

technical field

The utility model relates to a building sewer system, in particular to a building wastewater secondary utilization system.

Background technique

my country is one of the countries with serious shortage of water resources in the world, and saving water is one of the basic national policies of the country at present. Scientific utilization of domestic wastewater is one of the most effective ways to solve the current shortage of water resources in our country. At present, the building sewer system in my country basically discharges domestic waste water directly into the sewer pipe. This kind of building sewerage system is particularly unreasonable and unscientific for a country that is seriously short of water at present. Therefore, designing a secondary utilization system for building waste water is a technical problem to be solved at present.

Contents of the invention

The technical problem to be solved by the utility model is to provide a secondary utilization system of building wastewater that can scientifically utilize domestic wastewater.

The technical scheme that the utility model solves its technical problem is:

The secondary utilization system of building waste water is composed of the sewer pipe network of the building. A water storage tank is set in the toilet of the building. The sewer pipe of the water storage tank is connected with the water supply pipe of the toilet water tank behind the valve of the water supply pipe of the toilet water tank. connected.

The technical scheme that the utility model solves its technical problem can also be:

The utility model is provided with an overflow port on the upper mouth of the water storage tank, and the overflow port communicates with the building sewer pipe through the overflow pipe.

The beneficial effects of the utility model:

Compared with the downstream technology, the utility model can use part of the domestic waste water for toilet flushing water in the lower buildings without increasing any treatment costs.
