Drinking water treatment system

Abstract

The invention relates to a drinking water treatment system, which comprises a water inlet lift pump, wherein the water inlet lift pump is connected with an electromagnetic flowmeter; the electromagnetic flowmeter is connected with a pre-ozonation contact tower; the pre-ozonation contact tower is connected with a mixing flocculation settling pond; the mixing flocculation settling pond is connected with a sand filter; the sand filter is connected with a disinfection pond; a sand filter water lift pond is mounted below the disinfection pond. The drinking water treatment system has the benefits that the cost is low, and the effect of removal of organic substances and particles is excellent.

Description

technical field [0001] The invention relates to a drinking water treatment system. Background technique [0002] According to the "Summary Report on Water Quality Analysis Data of Source Water Monitoring Points at Shakou Water Inlets for the Year 2004 by Foshan Monitoring Station of the National Urban Water Supply Water Quality Monitoring Network", the annual change range of several major pollution indicators in Shakou water quality in 2004 is as follows: turbidity Degree 1.33-48.2NTU, odor and taste level 1, ODMn1.38-2.78mg / L, BOD5<0.03-2mg / L, CODCr<5-26mg / L, TOC3.14-6.57mg / L, DO5.9- 8.9mg / L, ammonia nitrogen <0.02-0.49mg / L, nitrite nitrogen 0.007-0.018mg / L. The raw water quality is good, close to the surface water environmental quality standard II, and meets the standard of centralized drinking water surface water source. However, there is a lot of rain in this area in summer, and high turbidity often occurs, with a maximum turbidity of more than 1000 NTU; accid...

AI Technical Summary

Problems solved by technology

However, there is a lot of rain in this area in summer, and high turbidity often occurs, with a maximum turbidity of more than 1000 NTU; accidents such as sewage, shipwreck, or oil spills caused by some upstream enterprises will cause intermittent pollution of water quality, resulting in organic pollutants, ammonia nitrogen, phenol, etc. In 2005, a total of 67 inspections of water sources were conducted, and a total of 14 sewage discharges were found at the coastal sewage outlets from Shiwan to Xinhuagang.
