Novel water treatment system

Abstract

The invention discloses a novel water treatment system, which comprises a filter mechanism consisting of a plurality of independent filter units, a water inlet pipe for introducing raw water, a water outlet pipe for leading out filtered water and a drainage pipe for draining back flush sewage, wherein each filter unit comprises a filter and a channel switching valve which is provided with a waterinlet part connected with a water inlet pipe, a water outlet part connected with the filter and a drainage part connected with the drainage pipe, and when the water inlet part and the water outlet part are connected, the filter unit is in a back flush state, and the water inlet part and the water outlet part as well as the drainage part and the water outlet part are connected and disconnected alternately for realizing the switching between the filtering state and back flush state of the filter unit. The system has the advantages that: the pipe arrangement is simple and reasonable; the cost islow; the filtering state and the back flush state can be performed at the same time without influencing each other; and the water treatment efficiency can be improved effectively, and the treatment effect is saved.

Description

technical field [0001] The invention belongs to the technical field of water treatment, in particular to a water treatment system with filtering and backwashing functions. Background technique [0002] With the progress of industry and social development, water pollution is becoming more and more serious, and it has become the world's number one environmental governance problem. Water pollution affects industrial production, increases equipment corrosion, affects product quality, and even makes production impossible; at the same time, it affects people. Living, destroying ecology, directly endangering people's health, and causing great damage. For this reason, raw water generally needs to be filtered, precipitated, and disinfected by a water treatment system before it can be supplied to industry and civilian use. For example, the filtration device of the current large-scale industrial filtration system is often composed of multiple filtration units to meet the demand for in...

Problems solved by technology

The disadvantages of the above two cleaning methods are: both need to be carried out in the shutdown state, and it takes a certain amount of time to clean the system before restarting the system. The filtration state and backwash state of the water treatment system cannot be carried out at the same time, and the treatment efficiency is low.

The State Intellectual Property Office of China published a patent with the patent number "200920204257.3" and the name "Sewage Treatment System" on 2010-06-16. Two pipelines are established in the system for water intake during normal filtration and water intake during backwashing water, and both pipelines are powered by a water pump, but setting up two pipelines will still bring inconvenience to the pipeline layout of the system. Although filtering and backwashing can be carried out simultaneously, they are all based on unfiltered Raw water is used as the water source, and raw water is used to flush membrane components during backwashing, which is likely to cause secondary pollution, low flushing efficiency, and ineffective effect
