System for treating waste water discharge in three-flow-merge mode by using collection pipelines and discharge pipelines

Abstract

The invention relates to a waste water treatment system, in particular to a system for treating waste water discharge in a three-flow-merge mode by using collection pipelines and discharge pipelines, which comprises light pollution water discharge pipes, heavy pollution water discharge pipes, light pollution water collection pipes, heavy pollution water collection pipes, a three-way valve, a bending head, a control valve and a main water drain pipe, wherein vertical pipes of the three-way valve are arranged at the vertical sections of a plurality of light pollution water discharge pipes, the lower ends of the vertical pipes of the three-way valve are connected with the light pollution water collection pipes, transverse pipes of the three-way valve are connected with the heavy pollution water collection pipes, control valves are arranged at outlets of water discharge pipes of the light pollution water collection pipes, and the heavy pollution water discharge pipes are connected with the main water drain pipe through the heavy pollution water collection pipes and the heavy pollution water discharge pipes. The waste water treatment system of the invention has the advantages of simple technology, smooth water discharge, large light pollution water collection amount, high utilization rate, good water saving effect and low construction design installation cost.

Description

1. Technical field: [0001] The invention is a technical solution for wastewater reuse, which belongs to an indoor drainage device system, and in particular relates to an indoor wastewater discharge, recovery and reuse pipeline system. 2. Background technology: [0002] The best way to save water is to improve the efficiency of water use, from one-time use of water to multiple use, and the water discharged after one use is called waste water discharge. Discharge after reuse, we call it discharge after reuse of wastewater. [0003] Domestic wastewater is recycled and collected, and after simple treatment, it is used as a secondary water source for car washing, toilet flushing, greening, irrigation, and industrial water, which will save a lot of primary water sources. There are many technical solutions and methods for wastewater reuse, no matter what kind of solutions and methods , there must be classification, diversion, confluence, collection and drainage of these links; a w...

AI Technical Summary

Problems solved by technology

[0004] At present, there are mainly two methods for the discharge of domestic wastewater commonly used in general: 1. One collection pipe and one confluence; 2. Two collection pipes and two confluence methods; the first method uses one collection pipe to connect all sanitary ware The water pipes connected to the utensils and the drains are connected in series, and the polluted water is discharged together regardless of whether it is light or heavy. , the light polluted water is sent to the reclaimed water treatment plant or other purification equipment or directly used for flushing after the collection and discharge pipes merge. When the drainage is not smooth, light polluted water cannot be discharged, some appliances cannot be used, and maintenance is inconvenient
