Embodiment 1

[0012] The content of iron and manganese in the groundwater of a certain village in southern my country seriously exceeds the standard, the iron content is 3.58-33.78mg / L, and the manganese content is 0.95-4.52mg / L. The drinking water purification system includes polysilicon thin-film solar cells, lead-acid batteries, solar controllers, sine wave inverters and reverse osmosis membrane separation equipment. The specific workflow is as follows:

[0013] (1) Polysilicon thin-film solar cells are irradiated by sunlight and convert light energy into electrical energy through the photoelectric effect;

[0014] (2) The electric energy generated by the solar battery enters the solar controller, and a stable current is obtained through digital adjustment, and then enters the lead-acid battery to charge it. When the battery power reaches full value, the solar controller automatically stops charging to prevent the lead-acid battery from being charged. overcharge;

[0015] (3) When the le...

Abstract

The invention discloses a drinking water purification system powered by solar energy, which comprises a solar cell, a storage battery, a solar controller, an inverter and membrane separation equipment. The solar controller is respectively connected with the solar cell and the storage battery; electric energy generated by the solar cell enters the solar controller first, is digitally adjusted and then charges the storage battery; current generated in the discharging process of the storage battery flows into the solar controller first and the direct current output by the storage battery is converted into alternating current (AC) through the inverter, so that the AC is conveniently used by AC electromechanical equipment in drinking water purification treatment; and the system can automatically switch to mains supply when the storage battery is short of power, and the normal operation of drinking water purification equipment is guaranteed in case of continuous cloudy and rainy days. The membrane separation equipment can remove organic pollutants, heavy metal ions, bacteria, viruses and other harmful substances from water, the water quality of effluent is stable, and high-quality healthy drinking water can be obtained. The system is energy-saving and clean, and high-quality drinking water can be obtained.

Description

technical field [0001] The invention relates to a direct drinking water purification system powered by solar energy, in particular to a direct drinking water purification system using solar cells to provide power. Background technique [0002] At present, surface water and groundwater, which are drinking water sources, are polluted to varying degrees. In the vast rural areas without tap water pipe networks, industrial and mining enterprises and troops far away from urban areas, it is difficult to guarantee the quality of drinking water. The conventional treatment technology of drinking water is the "old three-stage" process of coagulation sedimentation, filtration and disinfection treatment, which can effectively remove suspended solids, colloidal substances and bacteria and other pollutants in water, but it is harmful to metal ions, organic pollutants, dissolved chemical The removal of substances is limited, and the harm caused by water pollution cannot be completely elimin...
