Description

The invention relates to filters for the purification of water contaminated with suspended substances that can be used in the mining industry, namely in the coal, ferrous and non-ferrous metallurgy, chemical industry and building materials industry for the treatment of wastewater. mineral deposits.

The purpose of the invention is to reduce costs in the manufacture of the filter.

FIG. 1 shows the filter plan; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 - filter, the bottom of which used undisturbed waterproof indigenous rocks; in fig. 5 shows a section B-B in FIG. four; in fig. 6 - section G-Y in FIG. four; in fig. 7 - the filter, in the quality of the bottom and the walls of which unbroken waterproof bedrocks are used; in fig. 8 is a section d-d in FIG. 7; in fig. 9 shows section EE of FIG. 7

The filter includes the bottom 1, which uses undisturbed waterproof bedrock (Fig. 4-9) or waste rock formed during the development of coal deposits (Fig. 1-3), the filter wall 2, made of empty bedrock, is used as a filter. Waste from open-pit mining of coal deposits and forming a waterproof layer when interacting with a liquid (Fig. 1-6), or made of non-permeable, water-proof bedrock (Figs. 7-9); filtration chamber 3 filled with waste rocks formed during the development of coal deposits — sandstones; logo 4 for introducing water into the filtration chamber 3, located across the width of the filtration cell along the back wall of the filter; clean water collector 5, pipeline for supplying raw water 6 , a pipeline for collecting purified water 7, a transverse dam 8 made of porous bedrock, which is waste in the development of coal deposits (Fig. 8), which, when interacting with a liquid, form waterproof layer.

The method of making the filter is carried out as follows.

Select a place for the construction of the filter, align the platform under the bottom 1 and make it (Fig. 1-3). At the same time, waste rocks are used that are formed in the process of open-cast mining of mineral deposits. Their interaction with water is carried out. This forms a waterproof layer. Level the bottom and create a bias to the side.

the collector of purified water 5. Then pour out the steppes of the filter 2. To do this, use the empty bedrock formed in the process of open-cast mining of coal deposits and which, when interacting with the liquid, form a waterproof layer. A filter layer 3 is placed in the filter. For this purpose, waste rock formed during the development of coal deposits is used, for example sandstone. When this.m form a tray 4, which is placed along the rear wall of the filter. Thereafter, a pipeline 6 is laid for supplying contaminated water and a pipeline 7 for collecting purified water.

Undisturbed, water-proof rocks can be used to construct a filter 1 (Fig. 4-6).

The place for the construction of the filter can be chosen with the same calculation so that the bottom 1 and side walls of the filter 2 are untouched, water-resistant, native rocks of natural excavations, logs, ravines, beams, Bb coxuiHX rivers, etc. (Fig. 7-9).

As a filtering material for loading the filter, empty bedrocks are used, which are formed in the process of opencast mining of coal deposits.

Then a catchment tray 5 is made for purified water by dumping dam 8. Dumps are used as material for damming, which form in the process of open-cast mining of mineral deposits, which, when interacting with the liquid, form a waterproof layer.

The filter manufactured by this method works as follows.

Water to be cleaned is supplied either by gravity or forcibly through pipeline 6 to the receiving tray 4. Water from the receiving tray 4 gets into the layer of filtering material from the filtration chamber 3. As the water moves, the mechanical impurities settle in the pores of the filtration chamber 3 3. The movement of the cleaning water with my water directs the U-shaped arrangement of the wall of the filter 2. The purified water is collected in the water collector 5, from where it is supplied either by gravity or by pressure, through the pipeline 7 to the place of consumption.

As the lower layers of the filter chamber 3 are silted, the level of treated water in the primary tray 4 rises, and the overlying layers of filter-ni.ero material enter the work and so on until the silting chamber is completely silted. The filter can work 10 --- 15 years without stopping. After the volume of the filtration chamber is silted, the filter is stopped and another filter is put into operation.
