Abstract

The invention relates to the biological treatment of water on the slopes of a river gorge, in particular, surface polluted waters, which are discharged into mountain rivers. The purpose of the invention is to increase the efficiency and intensification of water purification. The device contains channels 3 with plants 4, bounded by blocks 5 and laid on gabion masonry 8. The bottom of the channel is a soil layer 9 on the filter 10 of sand and gravel material. The water that flows through the channels 3 is filtered through the layer 9, the filter 10 and the gabion wall 8. The channels 3 communicate with each other through a gabion fan-shaped weir. Gabion 8 works as a biofilter. The invention will reduce operational, energy and capital costs, as well as improve the quality of surface water flowing into the river. 2 Il.

The invention relates to the biological purification of water on the slopes of a river gorge, in particular, surface zag- / p known waters, which are discharged into mountain rivers.

The purpose of the invention is to increase the efficiency and intensification of water purification.

Fig. 1 shows a device for biological purification of water (frontal projection); FIG. 2 is a section, A-A in FIG. one ,

A device for the biological treatment of contaminated water entering through channel 1 contains a terrace 2, channels with full-flow bioplato 3 with aerial plants 4, bounded on one side by l-shaped blocks 5 fixed by anchors 6,

and on the other, frontal, side 7 - with a gabion masonry 8. The bottom of the channel represents the soil layer 9 on the reverse filter 10 of sand-gravel material. At the end of each channel there is a fan-shaped spillway 11 of gabion laying.

The device works as follows.

The surface flow of polluted waters is drained at the beginning of channel 3 from the first stage of terrace 2. Water, flowing through a full flow bioplate 3, is successively filtered through soil layer 9, the return filter 10 and gabion laying 8 Last, due to the small flow of infiltration flow and contact with the air from the frontal side of the 7 gabion clutch, located above the canal water mirror, works as a biological filter.

The flow at the end of each kg.

A different gabirin spillway 11 into the next channel 3 and mixed with the infiltration flow of the previous stage. The overflow works as a filter dam and aerator.

The device is placed on. relatively small squares, in unsuitable areas of relatively cheap, mostly local materials.

Washing of biological filters is not required due to the possibility of self-regulation in natural conditions, which reduces operational performance. There are no drainage pipes and other special parts, as well as equipment and energy costs for the supply of water and air. For the root system of plants, favorable conditions are created when they come into contact with air. ,

The proposed device allows effective water treatment and improves the quality of the surface water flowing into the river.

Claims (1)

Invention Formula I I A device for the biological purification of water, containing a terrace, channels located one below the other with full-flow bioplato, filtering base and load, which are provided with In order to increase efficiency and intensify water purification, the load is completed in the form of gabion masonry, and the filter base is in the form of a soil layer and sand and gravel material, while the channels are communicated by means of a weir and gabion masonry, which is the base of the previous and ; walls of the subsequent channels. .
