a pure water machine

Abstract

The invention relates to a water purifier comprising an electrolysis unit and a film filtering unit. The electrolysis unit comprises a first electrode pair, a second electrode pair, an electrolysis power source, and a water tank. The water tank is provided with a first water inlet and a first water outlet, a first water permeable film and a second water permeable film made of non-conductive materials are arranged between the negative electrodes and the positive electrodes of the first electrode pair and the second electrode pair. Agglomerate porous adsorption materials are filled between the negative electrode of the first electrode pair and the positive electrode of the second electrode pair, and a first water outlet is arranged on the porous adsorption materials. The film filtering unit is provided with a second water inlet and a second water outlet, and the first water outlet is communicated with a second water inlet. During use, the negative electrode of the first electrode pair and the positive electrode of the second electrode pair directly contact with water in the water tank. The positive electrode of the first electrode pair, and the negative electrode of the second electrode pair contact with water seeping from the first water permeable film and the second water permeable film only. The water purifier can effectively remove pollutants in the water source and thoroughly sterilize the water source.

Description

technical field [0001] The invention relates to a pure water machine, which belongs to the technical field of drinking water terminal water quality treatment. Background technique [0002] At present, the water environment is deteriorating, and drinking water quality and safety accidents occur frequently, which has seriously endangered human survival. Water pollution is mainly caused by pollutants produced by human activities, including industrial pollution sources, agricultural pollution sources and domestic pollution sources. Increasing water pollution has posed a major threat to human survival and has become a major obstacle to human health, economic and social sustainable development. According to the investigation of the authoritative organization in the world, at least 20 million people in the world die every year due to drinking unsanitary water. Therefore, water pollution is called "the number one killer in the world". [0003] Most waterworks at home and abroad st...

Problems solved by technology

However, the protection of the filter membrane is not enough. Some organic matter is adsorbed on the filter membrane and cannot be decomposed, causing the membrane to fail. Activated carbon is easily contaminated by bacteria and becomes saturated and fails, and even becomes a breeding ground for bacteria to further block the filter membrane, etc.

The pre-treatment is unqualified, so that the reverse osmosis membrane or ultrafiltration membrane is seriously polluted and damaged.

The post-electrochemical treatment process will also bring many new problems, such as cathode reduction will generate nitrite, heavy metal ions cannot be filtered out, resulting in excessive heavy metals, etc., which will eventually lead to substandard water purifiers
