Two-stage single-process water treatment for temporary accommodation centers for people affected by accidents, catastrophes and natural disasters

摘要

The invention relates to water treatment systems and technology selection rational deployment temporary accommodation (ISD) of population affected by accidents, and natural disasters, particularly to a hydraulic engineering, in water treatment systems.; The technical result - an increase of reliability and efficiency of production of pure water from the source.; This is achieved in that the single-process two-stage water treatment system comprising the cleaning system disposed between the pump stations of the first and second lift, there is a microfilter, which is connected with a pumping station of the first lift on one side and with a vertical mixer to the other, wherein the input to the mixer from the microfilter carried out from below, and reagents are supplied in the reagent management lateral conical part of the riser mixer, the output of which is situated in its upper part is connected to the input contac Nogo brightener in its lower part, a device for disinfecting water located on the line connecting the contact clarifier and the clean water tank which is connected with a pumping station of the second lifting microfilter consists of a housing box form in which the channels for collecting wash water and Channels for its withdrawal and delivery, wherein the housing is mounted in the drum with the filter elements, which is connected with a drain pipe and funnels for water, and in the upper housing portion is set above the drum spray Device ystvo with an independent drive, consisting of a collector plate sprinklers and protective casing, the inlet of microfilter is located in the right channel to the wash water, and the tube is designed to completely empty the enclosure, - the left, each of the nozzles comprises a housing in which is molded screw fitting and the fluid supply, wherein the housing consists of two concentric, interconnected, cylindrical bushings bushings larger diameter and smaller diameter of the sleeve, the inside diameter of smaller sleeve coaxially e Located screw rigidly connected to its inner surface, for example pressed into it, the outer surface of the screw is a helical groove, and inside the screw has an opening with a screw thread and in the sleeve of greater diameter, coaxially located nipple rigidly mounted therein such as by a threaded connection, through the sealing gasket, the inside fitting coaxially formed cylindrical hole passing axially disposed in a diffuser, which is connected with the cylindrical second chamber formed inner surface of the smaller diameter sleeve and the end surface of the screw and the screw thread direction of the hole formed within the screw is opposite to the outer helical screw groove and the screw injector is made of hard materials: tungsten carbide, ruby, sapphire.
