Zero-discharge environmental-protection water extracting and purifying device

Abstract

The invention relates to a zero-discharge environmental-protection water extracting and purifying device, wherein a pedestal is arranged in a well body, a well bore is arranged on the pedestal, and one water feeding space is arranged between the baseboard of the well bore and the lower part of the well body; a sand and water separation tube passes through the baseboard of the well bore and is provided with a through hole; a multi-layer flow guide clapboard is arranged between the outside of the well bore and the well body and filled with a filler; a converging well is connected with the well bore by a flow guide pipe. The positive effect of the zero-discharge environmental-protection water extracting and purifying device lies in that: water clarity, turbidity and matters seen by the unaided eye can reach the drinking water standard of the National Health Ministry after water is treated by the device, and the bacterial content is also reduced by a few times; in operation, waste water, waste residue and chemical residue cannot be discharged; zero discharge is achieved to the waste water; the device is totally buried below the beach surface to draw off floodwater and navigate, and the original landform and ecology cannot be damaged; what's more, by the device, the water can be safely extracted so as to solve the water crisis of the urban people and save the vast investment cost for the government.

Description

technical field [0001] The invention relates to a water intake device, which is suitable for the technical renovation and new construction of water plants for taking water sources from rivers; the daily water production capacity can be 300,000 m 3 The above devices are widely applicable to various water intake units. Background technique [0002] For a long time, the water plants and other water intake units adjacent to the river have followed the operation method for many years: directly take the water source of the river to the follow-up equipment for water purification treatment, and the treated water quality meets the standard before being used for drinking or industrial use. [0003] Such water purification treatment method has led to the following disadvantages: [0004] 1. At present, the water purification treatment of domestic water plants uses coagulants such as polyaluminum chloride and chlorine disinfection. There must be chemical residues in the treated water,...

AI Technical Summary

Problems solved by technology

[0005] 2. On average, 10%-15% of the sewage discharge after water purification treatment in the water plant, this part of the sewage discharge not only wastes the power consumption and water consumption in the extraction process, but more importantly, greatly pollutes the water resource environment

[0006] 3. The existing water plant occupies a large area, wasting land resources

[0007] 4. The water intake of the water plant has a large part of the protruding building on the river, which hinders flooding and navigation

[0008] 5. When sudden water pollution incidents occur or natural disasters such as landslides and mudslides cause the turbidity of raw water to exceed the limit of water control, water intake must be stopped, and the entire water supply system is paralyzed, resulting in a water crisis in the city

[0009] 6. The overall operating cost is high, which increases the water price burden of ordinary people
