Single-process water purification system

Abstract

The single-flow water purification system comprises a raw water treatment area, a clear water area and an air inlet area, the raw water treatment area is provided with a raw water inlet pipeline, a separation membrane pipe is horizontally laid, the clear water area is communicated with the water outlet end of the separation membrane pipe, an air distribution and mud separation partition plate is arranged below the separation membrane pipe, and a mud discharge filter head and an air flushing filter head are distributed on the air distribution and mud separation partition plate. The sludge discharging filter head and the air flushing filter head comprise a filter cap and a filter handle, the filter cap is located above the air distribution and sludge separation partition plate, the filter handle penetrates through the air distribution and sludge separation partition plate downwards, granular rough surface bodies are spread on the air distribution and sludge separation partition plate, a sludge collecting hopper is arranged below the air distribution and sludge separation partition plate, a sludge discharging pipe used for discharging sludge to the outside is arranged in the sludge collecting hopper, and a scum overflow groove is formed above a separation membrane pipe. The scum overflow groove is communicated with a scum overflow pipe for discharging scum to the outside, the air inlet area is communicated with the air inlet end of the separation membrane pipe, and the raw water treatment area is provided with an air inlet pipeline for feeding air into a hole in a filter handle of the air flushing filter head. The investment cost can be greatly reduced; the construction period can be greatly shortened, and the production water supply speed can be greatly advanced.

Description

technical field [0001] The invention relates to the field of environmental protection water supply and drainage treatment, in particular to a single-flow water purification system. Background technique [0002] At present, two types of water purification processes are generally used, one is conventional process treatment technology, that is, the "old fourth stage" conventional water treatment technology process: feed water (raw water or turbid water) --- "dosing (adding flocculation) agent system)---"Mixing (mechanical or mixer mixing)---"Reaction flocculation (reaction tank device)---"Sedimentation (sedimentation tank)---"Filtering (various filters)---" Effluent (clear water) ---" multi-process technology such as residential users. Its defects and disadvantages are: many process sections, complex processing, many structures, large area, high engineering cost, huge investment, long construction period, slow production, complex management, large number of operators, high ope...

AI Technical Summary

Problems solved by technology

Its defects and disadvantages are: complex process, many structures, expensive membrane price, short service life (generally about 4 years to update the membrane group), expensive project cost, huge investment, long construction period, slow production, complicated management, regular chemical cleaning, inevitable It will seriously affect water quality, high operation and maintenance costs, short membrane service life, expensive replacement costs and affect normal water supply. The chemical cleaning agent and the replaced waste membrane will seriously pollute the environment, etc.
