Problems solved by technology

It can be seen that the current scheme only recycles part of the wastewater, and the recycling method is mainly in the form of reclaimed water reuse. Therefore, it is necessary to develop a comprehensive reclaimed water reuse system, which is conducive to solving the current shortage of water resources and The problem of pollution discharge and environmental protection pressure

Embodiment 1

[0058] Example 1: An example of reclaimed water reuse project - MBR water treatment system.

[0059] According to the requirements of different discharge water quality and process water, this example realizes highly automatic control through the combination of multi-media filtration, ultrafiltration, nanofiltration, reverse osmosis and other processes, and realizes the recycling of water resources while reducing sewage discharge for enterprises. The water cost is further reduced, which has significant economic and social benefits.

[0060] In the MBR water treatment system, the sewage water supply pump, fan, suction pump, MBR tank circulation pump (and aerobic tank circulation pump), and reclaimed water supply pump can all be started manually (with switches). The suction pump acceleration and deceleration time is 10 seconds. There are 3 electronic flowmeters on the MBR water treatment system to be transmitted to the PLC for display. There is an electronic flowmeter on the pu...

Abstract

The invention discloses a sewage reuse system and a sewage treatment method. The sewage reuse system comprises a sewage treatment system and a reclaimed water reuse system, wherein the sewage treatment system comprises a primary water treatment system and a secondary water treatment system, the primary water treatment system is used for treating domestic produced sewage to form wastewater and reuse water, and the secondary water treatment system is used for treating the reuse water to form residential domestic water and reclaimed water; and the reclaimed water reuse system is used for conveying treated waters from the sewage treatment system to different use occasions according to the quality of waters. The treatment method comprises the following steps: treating the domestic production sewage by the primary treatment system to form wastewater and reuse water, and treating the reuse water to obtain domestic water consumption standard reaching water used as the residential domestic water and domestic water consumption standard unreaching water used as the reclaimed water. The above technical scheme alleviates the shortage of water resource and the pressure of pollution discharge and environmental protection.

Description

technical field [0001] The invention relates to a sewage treatment system, in particular to a sewage reuse system and a sewage treatment method. Background technique [0002] The shortage of water resources and the environmental pressure of sewage discharge restrict the development of my country's economy and society. Therefore, various industrial enterprises and municipal sewage plants have tried to carry out advanced sewage treatment and reuse of reclaimed water in order to realize the utilization of sewage resources, better protect the environment, and solve water problems. [0003] figure 1 Shown is a schematic diagram of the utilization of water resources in the prior art. Natural water or groundwater is transported to the water supply company, and after being treated by the water supply company, domestic water or industrial water is transported outward. The domestic water is used by municipal sewage The treatment station conducts treatment, and part of the treated wa...
