Problems solved by technology

On the other hand, the increasingly complex water quality conditions and higher standards of drinking water quality requirements have also become a major contradiction, which drives water treatment researchers to devote themselves to the exploration and improvement of filtration technology, so scholars still Carry out research work on filtration technology and theory to seek more cost-effective filtration technology
[0004] In the existing technology, the filtration speed of water treatment is slow, and the design of the filter tank is too short, which blocks the increase of the flow rate of the filter device, and the actual operation effect of the filter tank is not good.
The design of the filter in the prior art has a small amount of water, the effluent quality is not up to standard, and the connection with the front-end structure is unreasonable. The form of the filter is single. etc.) cannot be adjusted and cannot be guaranteed to fully play its role in changing sewage

Abstract

The invention discloses a vertical type rapid water purifying device and a water purifying method thereof. The vertical type rapid water purifying device consists of a raw water tank, a water feeding device, a filter tank, a water outlet pipe, a backwashing device, a clean water tank, a sludge discharge pipe, a bracket, a sludge collecting tank, a stirring water distribution device and a control system; raw water in the raw water tank is conveyed to the upper part of the front of the filter tank by the water feeding device, enters the filter tank, then, is subjected to dispersed flowing from top to bottom by the stirring water distribution device and finally is drained into the clean water tank from the water outlet pipe located at the left side of the bottom of the filter tank; after a system runs for two hours, valves on the water feeding device and the water outlet pipe are manually closed, then, clean water is conveyed to the bottom of the filter tank from the clean water tank by the backwashing device, slowly rises from the bottom of the filter tank and finally is drained through the sludge discharge pipe; twenty minutes later, valves on the backwashing device and the sludge discharge pipe are closed, the valves on the water feeding device and the water outlet pipe are opened again, and the device is in cycle operation in this way. The vertical type rapid water purifying device and the water purifying method thereof, disclosed by the invention, are reasonable in design and good in treatment effect and are applicable to the refiltering treatment of water treated by various sedimentation devices.

Description

technical field [0001] The invention belongs to the field of water purification devices, in particular to a vertical fast water purification device. Background technique [0002] Filtration is an essential and critical link in the water treatment process. Filtration is a process of further purifying water through the interception and adhesion of suspended impurities in water by granular filter material layers (quartz sand, anthracite) in the conventional processes of coagulation, sedimentation, filtration, and disinfection. The filter is placed after the sedimentation tank or clarification tank in the surface water purification plant that uses river water or lake water as the water source, as the last process of removing suspended solids. The important role of the filter is reflected in the removal of suspended solids and colloidal substances in the water. The filter can effectively reduce the turbidity in the water, which means that some bacteria, viruses, insects, and org...
