Zero-discharge water purification system for high-rise building

Abstract

The invention discloses a zero-discharge water purification system for a high-rise building. The zero-discharge water purification system comprises a water purifier, a wastewater storage tank, a central controller, a terminal controller, a heater and a hot water heat preservation tank; a water inlet of the water purifier and a water inlet of the wastewater storage tank are respectively communicated with a tap water pipeline; a purified water outlet of the water purifier is communicated with the heater through a purified water pipeline, a water outlet of the heater is communicated with a hot water inlet of the hot water heat preservation tank, and the hot water heat preservation tank is communicated with a purified water hot water port; a wastewater port of the water purifier is communicated with the wastewater storage tank through a wastewater pipeline, the top of the wastewater storage tank is communicated with a drainage pipeline, the bottom of the wastewater storage tank is communicated with other water pipelines, other water ports are formed in the other ends of the other water pipelines, and a purified water cold water port is further formed in one end, away from the water purifier, of the purified water pipeline; the central controller is electrically connected with a water pump on the tap water pipeline, and the terminal controller is electrically connected with the heater. The purpose of saving water in the high-rise building is achieved.

Description

technical field [0001] The invention relates to the technical field of water purification systems, in particular to a zero-discharge water purification system for high-rise buildings. Background technique [0002] There are three main methods of conventional water supply systems for high-rise buildings. The first is to place water tanks on the roof. Users use the water in the water tanks and rely on potential energy to form water pressure to meet water demand. The second is to use a booster pump to control the pump motor through the frequency conversion system to control the speed of the pump according to the change of the water supply pressure. The water pump absorbs water from the municipal pipe network and directly supplies it to high-level users. The third is the air pressure tank water supply device. The water pump absorbs water from the municipal network pipe and supplies it to the air pressure tank. The compressed gas in the air pressure tank is used to press the wate...

AI Technical Summary

Problems solved by technology

Due to the long-term operation of the water pump, the wear and tear is serious, and problems often occur, which increases the maintenance cost

Moreover, due to improper water supply methods and operating procedures, they are often affected by water hammer from high-level water supply, and the service life of water pumps, valves and pipelines is greatly reduced.
