Embodiment Construction

[0025] An integrated treatment process for treating drinking water exceeding the standard in rural areas, comprising the following steps:

[0026] (1) The raw water exceeding the standard is subjected to conventional sedimentation treatment in the water storage buffer tank to remove large particles of impurities and coagulation, reduce the turbidity exceeding the standard, and obtain water with a turbidity ≤ 100 NTU.

[0027] (2) Put water with turbidity ≤ 100NTU into the multi-media filter through the feed pump to remove colloidal substances, suspended solid particles, sediment, some macromolecular organic substances and microorganisms, and obtain turbidity ≤ 1 NTU and SDI < 3 of water.

[0028] Among them: multi-media filter refers to a multi-level filter composed of one layer of quartz sand and one layer of anthracite, arranged from large to small, and from bottom to top.

[0029] (3) Add scale inhibitor to water with turbidity ≤ 1 NTU and SDI < 3 through the dosing system...

Abstract

The invention relates to an integrated treatment process for treating rural drinking water exceeding the standard. The process comprises the following steps: (1) performing conventional precipitation treatment on the exceeding standard raw water in a water storage buffer tank to obtain water with turbidity ≤ 100 NTU; The water of ≤100NTU enters the multi-media filter through the feed pump to obtain water with turbidity ≤1NTU and SDI<3; (3) Add scale inhibitor to the water with turbidity ≤1NTU and SDI<3 through the dosing system. After mixing, add hydrochloric acid to make the pH value of the mixed solution 6.8-7.2 to obtain acid-adjusted water; (4) pass the acid-adjusted water through a precision filter and a pressure pump in turn and enter the membrane module filtration system for filtration , to obtain fresh water; (5) after the fresh water is sterilized by an ultraviolet sterilizer, standard drinking water is obtained. The present invention comprehensively utilizes advanced and applicable water treatment technologies and devices such as filtration, adsorption, and disinfection, as well as membrane technologies such as microfiltration, ultrafiltration, nanofiltration, etc., to process safe drinking water in rural areas.

Description

technical field [0001] The invention relates to the field of drinking water treatment, in particular to an integrated treatment process for treating drinking water exceeding the standard in rural areas. Background technique [0002] 70% to 80% of the human body is water. Long-term drinking of poor water quality will lead to poor physical fitness and naturally weakened resistance. All diseases are inevitable. Moreover, when the long-term accumulated pollutants reach the body's unbearable, no matter how clever No matter how effective the medicine is, it may not be effective, so there is a saying that "water is the king of all medicines". According to the "Rural Drinking Water Safety and Sanitation Evaluation Index System", the overall level of rural water supply in my country is not high, and more than 300 million people still have unsafe drinking water, which seriously affects the health and normal life of the masses. Due to the increasingly serious pollution of water bodies...
