Embodiment 1

[0051] like Figures 1 to 2 As shown, this embodiment provides a method for urban water storage, water supply and drainage without a municipal sewage pipe network, including the following steps:

[0052]S1. Set up sewage sedimentation ponds, sewage artificial wetlands, sewage treatment equipment, reservoirs, urban water pipeline networks, water purification equipment, river canal artificial wetlands, urban canals, lakes, lake artificial wetlands and rivers; wherein, the sewage treatment The equipment is MBR membrane bioreactor sewage treatment equipment. The MBR membrane bioreactor sewage treatment equipment can effectively treat urban domestic sewage and industrial wastewater and other industrial equipment, and meet the domestic water standard to prevent sewage and pollutants from directly flowing into the water area. Improve the ecological environment and improve the utilization rate of water resources;

[0053] S2, using the sewage sedimentation tank to remove suspended so...

Embodiment 2

[0066] like figure 2 As shown, this embodiment provides an urban water storage, water supply and drainage system without a municipal sewage pipe network, including a sewage sedimentation tank, a sewage constructed wetland, sewage treatment equipment, a water storage tank, an urban water pipeline network, water purification equipment, and river channels. Constructed wetlands, urban canals, lakes, lake constructed wetlands and rivers.

[0067] Among them, the water purification equipment can be selected from general water quality processors, mineralized water devices and reverse osmosis water treatment devices.

[0068] A general water quality processor refers to a drinking water quality processor that uses municipal tap water or other centralized water supply as the water source and is further processed to improve the quality of drinking water and remove certain harmful substances in the water.

[0069] The mineralized water purifier refers to the drinking water purifier that...

Embodiment 3

[0076] Based on Embodiment 1, this embodiment provides a method for removing the municipal sewage pipe network, using the urban water storage, water supply and drainage method without the municipal sewage pipe network described in Embodiment 1, to remove the municipal sewage pipe network in the town, and in the removal After the municipal sewage pipe network in cities and towns, the on-site treatment of urban sewage, on-site storage and on-site recycling and utilization, has been achieved, and the purpose of using rivers, canals and lakes for storage and utilization to meet urban water resources; urban communities or parks or scenic parks or woodlands are realized The recycled rainwater and remaining grey water are shared with the fresh water of rivers and lakes.

Abstract

The invention relates to an urban water storage, water supply and drainage system and method without a municipal drainage pipe network, and the method comprises the steps: preliminarily purifying sewage discharged by urban users through a sewage sedimentation tank to obtain primary clean water; purifying the primary clean water and municipal rainwater through a sewage constructed wetland to obtain secondary clean water; purifying the second-stage clean water by using sewage treatment equipment to obtain third-stage clean water, and storing the third-stage clean water into a reservoir; purifying water discharged from the urban canals by utilizing the canals constructed wetland to obtain canals clean water; conveying the clean water of the canals and/or the three-stage clean water in the reservoir into the urban canals and/or a water supply system of urban users by using an urban water conveying pipe network; water in the canal and the lake is purified by utilizing the canal and lake constructed wetlands respectively and then is discharged into the river; according to the invention, on-site treatment, on-site storage and on-site recycling of town sewage are realized, and the purposes of removing a town sewage discharge pipeline system and perfecting water storage, water supply, flood control and water drainage in cities and towns are achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment technology and municipal water supply and drainage pipe network, in particular to an urban water storage water supply and drainage system and method without a municipal sewage pipe network. Background technique [0002] The urban domestic sewage, industrial wastewater and rainwater basically enter the urban sewage pipeline after being discharged, and are treated in the urban sewage treatment plant, and then discharged from the urban underground drainage pipeline after treatment. The municipal sewage pipe network in cities and towns not only requires a large investment, but also cleans the sludge every year, and also regularly treats the sludge of the sewage treatment plant. [0003] Urban canals are only drainage channels, lakes can only rely on rainwater to replace water quality, and domestic sewage cannot be connected to lakes. It is used to connect the remaining reclaimed water with r...
