The partition wall, through which the upward flow filter passes.

The technical principle of the utility model: the raw water enters the downward flow filter tank through the water inlet, and under the action of the filter layer of the downward flow filter tank, the larger suspended matter in the raw water is absorbed and captured, and is passed through the long handle by gravity. The filter head goes to the water passage of the downward flow filter; the raw water enters the water passage of the upward flow filter from the water passage of the downward flow filter through the water hole and the air hole of the first partition wall, and passes through the downward flow There are fine suspended solids in the raw water, and then the fine suspended solids are captured and intercepted by the fiber filter layer in the upward flow filter, and the raw water flowing out of the upward flow filter layer passes through the upward flow filter and The second partition wall between the clear water pools overflows into the clear water pools, and the whole filtration process is completed. When the interception and capture efficiency of the filter layer of the integrated equipment filter reaches the limit, and the filter layer penetrates, backwashing is required. When backwashing, the backwashing system at the bottom of the clear water pool starts to work, and the filtered water is backwashed upwards and downwards. Flow filter, upward flow filter, the backwash effluent is drained from the backwash outlet on the upper part of the side wall of the downward flow filter and the upward flow filter respectively. When the backwashing water changes from dirty sewage to clean water, the backwashing of the filter layer is over, and the entire backwashing is over, and the filtration will start again.

Compared with the prior art, the beneficial effects of the utility model are:

① The integrated equipment for the combined use of the filter tank and the clean water tank combines the filter tank and the clean water tank into one body, and has a simple structure and low manufacturing cost.

②When treating water, the combined effect of the downward flow filter and the upward flow filter can treat the water quality more thoroughly.

③Filtered water directly enters the clear water tank, eliminating the need for intermediate transmission of the pipe network.

Below in conjunction with accompanying drawing and embodiment the utility model is described further.
