DETAILED DESCRIPTION - An integral water purifying device of solar photovoltaic power supply comprises a solar power supply system, a chemical agent mixing and feeding system, and a water treatment system. The solar power supply system is formed by a solar battery array (13), a photovoltaic controller (16), an accumulator battery (15), an inverting control cabinet (17) and alternating (AC) load. The solar battery array is supported by a battery bracket (14), and directly absorbs sunlight, and converts the light energy into electricity. The accumulator battery comprises an accumulator battery and a battery rack. The accumulator battery is an energy storing device of solar photovoltaic power supply system, each 48 V/500 AH is one group provided with a battery cabinet that measures voltage and current of accumulator and single section battery. The photovoltaic controller is respectively connected with solar battery array and accumulator battery, which is to adjust and control the direct current (DC) power energy generated by the battery, on the one hand, the adjusted direct current is used for providing electricity for load, on the another hand, the redundant energy is sent to the accumulator battery for storing. The inverter control cabinet is connected with photovoltaic controller and the AC load, which converts the DC power supply into AC power supply for AC load device. The chemical agent mixing and feeding system comprises polyaluminum chloride (PAC) agent feeding tank (36), PAC metering pump, polyacrylamide (PAM) feeding tank (38) and PAM metering pump. After PAC (35) is doped in the PAC feeding tank, it is put in a lower solution layer through agitating and mixing with water on upper layer chemical agent dissolving pool of PAC feeding tank by PAC agitator (4), then it is pumped to PAC pipeline mixer (6) by PAC metering pump (5) to mix with sewage (1). In the same way, after PAM (37) is doped in PAM feeding tank, it is put in a lower solution layer through agitating and mixing with water on upper layer chemical agent dissolving pool of PAC feeding tank by PAM agitator (7), then it is pumped to PAM pipeline mixer (9) by PAM metering pump (8) to mix with the sewage. The inverter control cabinet is respectively connected with sewage pump (3), PAC agitator, PAC metering pump, PAM agitator and PAM metering pump via lead wire. The water treatment system comprises a sewage tank (2), a sewage pump, an integral purifying device, a clean water tank and an outlet pipe. The sewage flows to the sewage tank and is pumped in an integral water purifying device (10) by the sewage pump (3), the water outlet (11) is communicated with an integral water purifying device and a clean water tank (12). The qualified water through processing is stored in the clean water tank. The sewage tank is provided with a sewage liquid level sensor (33), and the clean water tank has a clean water liquid level sensor (34).
