BACKGROUND OF THE INVENTION 
     Technical Field 
     The invention relates to water treatment equipment, in particular to a primary filter and storage system. 
     Description of Related Art 
     Existing fresh water resources which can be easily utilized by humans are mainly from rivers, lakes and shallow groundwater; the fresh water resources are deficient due to large consumption, and clean water resources in places with abundant electricity and energy are also relatively deficient and need to be saved and protected due to serious pollution and extremely imbalanced regional distribution; water resources have already been precious resources for humans, and water resource problems even become a major strategy concerning sustainable development of the national economy and society, and lasting political stability. 
     In certain remote arid and distressed areas where clean water resources are extremely difficult to obtain and water resource shortages exist, it is hard to lay long delivery pipelines for long-distance supply of drinking water, or to transport drinking water back and forth through transportation facilities without considering transportation costs, or to mount large water quality optimization systems, and consequentially, the cost of safe drinking water becomes extremely high; besides the high drinking water cost, water quality changes or secondary pollution can be caused by long-distance delivery or transportation, and consequentially, water cannot be directly drunk by people safely. 
     Although the personal demand for drinking water of people in daily life is not large, the requirements for the sanitation, cleanliness, sterility and non-toxicity of the drinking water are high; drinkable pure water can be obtained through air purification and condensation, however, the pure water obtained simply through air purification and condensation still cannot reach the standard of high-quality drinking water and needs to be further optimized to reach the water quality standard of the high-quality drinking water. 
     BRIEF SUMMARY OF THE INVENTION 
     For solving the technical problems, the invention provides a primary filter and storage system which can pre-treat water when pure water obtained through air purification and condensation is further optimized.

     According to the primary filter and storage system, the filter device comprises a fiber mesh filter, a PP cotton filter, a quartz sand filter, a particle carbon filter and an active carbon filter. 
     According to the primary filter and storage system, the fiber mesh filter, the PP cotton filter, the quartz sand filter, the particle carbon filter and the active carbon filter are sequentially connected in series, the fiber mesh filter is connected with the water source through the water pump, and an outlet of the active carbon filter is connected with the ultraviolet sterilization device. 
     According to the primary filter and storage system, the control circuit comprises a controller, the water storage device comprises a plurality of water containers, each water container comprises a water level alarm device, a water inlet electromagnetic valve and a water outlet electromagnetic valve, and the signal output end of each water level alarm device, the control end of each water inlet electromagnetic valve and the control end of each water outlet electromagnetic valve are all connected with the controller; the control end of a water pump driving circuit is connected with the controller. 
     According to the primary filter and storage system, the power source is a solar power source. 
     The primary filter and storage system of the invention can be used for primary optimization and storage of pure water obtained through air purification and condensation, and thus the pure water can be further optimized by the next-stage water purification system conveniently to reach the standard of optimal drinking water.

     DETAILED DESCRIPTION OF THE INVENTION 
     The FIG. shows the structure of a primary filter and storage system of an embodiment of the invention, and the primary filter and storage system comprises a power source, a high-pressure water pump, a filter device, an ultraviolet sterilization device, a water storage device and a control circuit, wherein an inlet of the filter device is connected with a water source, and an outlet of the filter device is connected with the ultraviolet sterilization device; an outlet of the ultraviolet sterilization device is connected with the water storage device. 
     Wherein, the filter device comprises a fiber mesh filter, a PP cotton filter, a quartz sand filter, a particle carbon filter and an active carbon filter. The fiber mesh filter, the PP cotton filter, the quartz sand filter, the particle carbon filter and the active carbon filter are sequentially connected in series, the fiber mesh filter is connected with the water source through the high-pressure water pump, and an outlet of the active carbon filter is connected with the ultraviolet sterilization device. 
     The control circuit comprises a controller, the water storage device comprises a plurality of water containers, each water container comprises a water level alarm device, a water inlet electromagnetic valve and a water outlet electromagnetic valve, and the signal output end of each water level alarm device, the control end of each water inlet electromagnetic valve and the control end of each water outlet electromagnetic valve are all connected with the controller; the control end of a high-pressure water pump driving circuit is connected with the controller. 
     In the embodiment, the power source is a solar power source. 
     The primary filter and storage system of the embodiment of the invention can collect the water source of a plurality of air purification and condensation water-production systems, for avoiding the influence on the water-production quantity and the increase of the size of a machine body, only simple filtration is conducted by the water-production systems, and the primary filter and storage system is responsible for major water source filtration and purification after water-production; all water source filtration, purification and sterilization work of the system is promoted through the high-pressure water pump, the operating condition and information of the system are monitored through the controller of the control circuit of the system in each procedure, and the operating information, the system working condition and alarm information are summarized and synchronously transmitted to a master control system of a central control room through the controller.
