Method for filtering various water sources into drinking water

Abstract

The invention discloses a method for filtering various water sources into drinking water. In the method, a first-level biological purification water preparation unit is added before the conventional water treatment process according to a water purification principle; pollutants harmful to a human body are removed from water without performing sterilization by using ozone and chlorine; a water purification device manufactured by the method has a simple structure and low water preparation cost and is reliable to operate; and people in vast rural areas and rural towns can drink and use the purified water produced by the device. The method is implemented by the following technical scheme: the public biological purification water preparation unit and the conventional water purification treatment unit are designed and manufactured into standard combined filter element modules; according to the sequence of a water purification treatment process, the combined filter element modules are buckled from top to bottom into a tower-shaped water purification device; according to requirements of different water sources and different clients, the modules of the combined filter elements by different processes are replaced only according to the local water quality condition, so that various water sources are filtered into the driving water.

Description

technical field [0001] The invention relates to a water purification and filtration method, and more specifically, the invention particularly relates to a method for filtering various water sources into direct drinking water. Background technique [0002] At present, the conventional preparation method of all kinds of direct drinking water sold in China's market is to remove the residual pollutants and bacteria in the tap water through ozone oxidation, activated carbon adsorption, ultrafiltration, reverse osmosis filtration, chlorine disinfection or ozone disinfection. , viruses, improve the quality of tap water, and then seal it into bottled water or barreled water through a filling machine, or send it to the community through pipelines for residents to drink; this conventional method of purifying and filtering water mainly uses the addition of coagulants The coagulant reacts with impurities in water to remove impurities, mainly colloids and suspended solids in water; the p...

[0002] At present, the conventional preparation method of all kinds of direct drinking water sold in China's market is to remove the residual pollutants and bacteria in the tap water through ozone oxidation, activated carbon adsorption, ultrafiltration, reverse osmosis filtration, chlorine disinfection or ozone disinfection. , viruses, improve the quality of tap water, and then seal it into bottled water or barreled water through a filling machine, or send it to the community through pipelines for residents to drink; this conventional method of purifying and filtering water mainly uses the addition of coagulants The coagulant reacts with impurities in water to remove impurities, mainly colloids and suspended solids in water; the properties of fine suspended solids are similar to those of colloids, so removing colloids in water is the main purpose of water treatment; When most of the water is removed, most of the bacteria generated by using it as a carrier will also be removed; adding a coagulant or flocculant to the water to destroy the stability of the colloid in the water and flocculate the colloid and suspended matter in the water To form larger flocs in order to separate them from the water and achieve the purpose of water purification, but the essence of adding coagulants is that they cannot kill bacteria and often have a strong odor in the water, so chlorine or ozone should be added to the water. Disinfection, add activated carbon equipment to remove peculiar smell, so that drinking water often contains carcinogenic residues of ozone and chlorine disinfection; due to the use of high-end technology equipment with dosing, operation management becomes very complicated, water treatment equipment is expensive, and it is harmful to influent water High water quality requirements, high energy consumption, high cost of water production, large floor area, inconvenient operation and management, has been unable to meet the needs of more than 80% of the country's rural, township population, and direct drinking water
