Detailed Description

The preferred embodiment of the solar advanced wastewater treatment system is described in detail below with reference to the accompanying drawings.

Fig. 1, 2 and 3 show the specific embodiment of the solar deep wastewater treatment system:

with reference to fig. 1, 2 and 3, the solar deep sewage treatment system comprises an intermediate water tank, an anaerobic filter tank and a BAF biological aerated filter tank which are sequentially connected through a pump and a water pipe, wherein a CLO2 generator is connected with the BAF biological aerated filter tank through an air blower, the BAF biological aerated filter tank is connected with a filtrate return regulating tank, the BAF biological aerated filter tank is sequentially connected with a mixed filter material tank and a discharge water tank through a pump and a water pipe, the discharge water tank is connected with the mixed filter material tank through a backwashing pump, and the discharge water tank is connected with the filtrate return regulating tank. All equipment in this solar energy degree of depth sewage treatment system adopt the solar energy supply, and the electric energy is cleaner, more energy-concerving and environment-protective.

The purpose of additionally arranging the middle water tank is to play a role in buffering. The effluent collecting tank of the original air floatation system is utilized. (volume about 100 m)³). 2 middle water pumps and 2 liquid level controllers are arranged in the middle water tank. The waste water in the middle water tank is pumped into the anaerobic filter, the BAF biological aerated filter and the discharge tank in the following sequence by a middle water pump.
