Description

The invention relates to the purification of natural waters and the purification of wastewaters, and can be used primarily for the preliminary purification of water before it is fed to filtering facilities. Known clarifier with suspended sediment, comprising a circular case in terms of, divided by two horizontally installed partitions from which the top is made perforated, and the bottom is deaf, into three compartments. The upper compartment communicates with the lower through vertically installed pipes. In the well-known clarifier, the lower compartment plays the role of precipitator C. The disadvantage of the clarifier is the difficulty of removing sediment from the precipitator, which is associated with the necessity of emptying the clarifier. clarity, complicates its operation. A suspended sedimentation clarifier is also known, which includes a circular case with a vertical, divided vertical-type partition wall into two compartments, communicating through one-level openings in the partition. The water being cleaned enters the outer compartment through obliquely arranged distribution pipes. In this clarifier, the conditions for removing deposits from sediment seal 21 are simplified. However, the presence of stagnant zones in the outer compartment, which make up to half of its volume, significantly reduces the technological and economic efficiency of the clarifier. In addition, the above illuminators with a suspended sediment in the plan are inconvenient when arranging and placing structures in a water treatment plant. The closest to the invention in terms of technical essence and effect achieved is a clarifier with suspended sediment, including a rectangular case, divided by vertical partitions into working chambers, between which a sludge compaction chamber with sediment-receiving windows in the side walls 3 is located. A disadvantage of the known clarifier is the uneven flow of water from the working chambers into the sludge compaction chamber. This leads to a deterioration of the precipitation of the suspension and clarification of the water in the chamber of the compacted sediment. The purpose of the invention is to increase the cleaning efficiency by increasing the uniformity of the intake and distribution of the sludge enters it from the working chambers from the working chambers. . To this end, a suspended sediment clarifier, including a rectangular case, divided by vertical partitions into working chambers, between which a sludge compaction chamber with sediment receiving windows in the side walls is located, is fitted with windows of opposite walls of the sludge compaction chamber. It is advisable to perforate pipes in their lower part. The drawing shows a clarifier with suspended sediment, a cross-section. The clarifier includes a housing 1, divided by two vertical partitions 2 into two working chambers 3 and 4, between which a sludge compaction chamber 5 is placed, communicating with the working chambers through perforated pipes 6. The ends of the perforated pipes 6 are mounted and embedded in windows V located on one level in partitions 2. Windows 7 on the side of chambers 3 and 4 are protected by peaks 8. In the lower part of chambers 3 and 4 distribution pipes 9 are laid for lightening the treated water, and in the upper part there are prefabricated chutes 10. In the lower part A part of chamber 5 is provided with perforated pipeline 11 for sludge removal, and in the upper part below the level of the gutter edge 10 (chambers 3 and 4) pipeline 12 for collecting and draining clarified water. The clarifier works as follows. The purified water with the necessary reagents introduced into it is fed through distribution pipes 9 into chambers 3 and 4. Passage through a layer of suspended sediment formed above distribution pipes 9; water is clarified, collected by chutes 10 and discharged (if necessary, j for further purification. To maintain a layer of suspended sediment at a constant level, a continuous passage of part of the water and sediment from chambers 3 and 4 to chamber 5 is performed. The overflow is carried out by means of perforated pipes 6. In chamber 5, water is clarified by sedimentation of the incoming sediment. Clarified water is collected by pipeline 12 and discharged, mixing along the way with water collected by troughs 10. The water level in chamber 5 is maintained below the water level in chambers 3 and 4, l.agodar
