That is, the sewage waste heat recovering and filtering apparatus according to the present invention is characterized in that sewage is filtered through a sand filter in another reverse tank while the waste water is filled in one of the reverse tanks and filtered through the heat exchanger in the other reverse tank The waste heat is recovered by supplying water, and the heat-exchanged water is discharged to the outside, whereby the waste water can be purified and the waste heat of the sewage can be recovered.

Although the waste water heat recovery and filtration apparatus according to the present invention has been described in terms of three reverse tanks according to the present invention, it is described as a minimum unit, and it is possible to increase the number of reverse tanks according to the flow rate of sewage discharged from the collection It will be appreciated that it is within the scope of the claims of the present invention to increase the number of reverse tank installations.

Here, the second valve V2 and the third valve V3 are closed while the first valve V1 is opened such that sewage is supplied to the first reverse tank RT1 from the collection tank 10. Similarly, when the second valve V2 is opened, the first valve V1 and the third valve V3 are closed. When the third valve V3 is opened, the first valve V1 and the second valve V3 V2) are closed.

The fifth valve V5 and the sixth valve V5 are opened so that the sewage filled in the first reverse tank RT1 is supplied to the sand filter 20 by the third pump P3 while the fourth valve V4 is opened. V6) are closed. The eleventh valve V11 and the twelfth valve V10 are opened while the tenth valve V10 is opened so that the filtered water in the sand filter 20 can be supplied again to the first reverse tank RT1 for circulation. V12) are closed. Thereafter, when the filtration process of the first reverse tank RT1 is completed, while the thirteenth valve V13 is opened so that the filtered water is supplied to the heat exchanger 30 from the first reverse tank RT1, And the fifteenth valve V15 are closed.

The sewage is filled in the second reverse tank RT1 and the third reverse tank RT3 and is filtered by the sand filter 20. During the process of the filtered water being supplied to the heat exchanger 30, Opening and closing of the valve described above with respect to the first reverse tank RT1.

The collector 10 is equipped with a roller type crusher 11 and a sieve 13 so that the sewage is sequentially passed through the crusher 11 and the sieve 13 when the sewage is supplied to the sump.

By this, a large volume of dirt contained in the sewage is finely crushed by the roller type crusher 11, and the volume of the dirt passing through the crusher 11 is still large is filtered by the filtering net 13.

The roller-type crusher 11 and the screen 13 are already known, and a detailed description thereof will be omitted.

A third pump P3 and a fourth pump P4 are mounted in parallel in the sewage supply pipe L8.

As a result, when the third pump P3 fails, the fourth pump P4 is driven, and the third pump P3 can be repaired while the fourth pump P4 is driven.

The flocculant supply pipe L17 is connected to the sewage supply pipe L8 supplied with sewage to supply the sewage to the sand filter 20 and the fifth pump P5 is installed to the flocculation pipe L17, And is supplied to the sewage supply pipe L8 by the pump P6.

As a result, the dirt particles included in the sewage can be greatly aggregated, and the sand filter 20 can filter the dirt contained in the sewage better.

The construction, operation and backwashing of the sand filter 20 are described in detail in Korean Patent No. 10-1509615 (registered on Apr. 1, 2015) of the present applicant "sand filter" .

The first pump P1 and the second pump P2 are arranged in parallel in the hot water supply pipe L16.
