Description

The invention relates to various industries and can be used to purify water from suspended thin-layer particles, petroleum products, metals and other impurities.

A known method of clarification of process water in underground water collectors with mechanized treatment [1]. The method is carried out in three stages in a uniformly moving stream of water along the length of the path of deposition of particles. At the first stage, floating foreign objects are selected in the zone of pulp reception to exclude their falling into transport mechanisms. At the next stage, the process of natural deposition of solid suspended particles of various sizes and specific gravities is intensified. At the last stage, clarified water is accumulated before it is discharged to the surface or for reuse of sludge in underground water collectors, to accelerate clarification of water for reuse, to reduce energy consumption when releasing underground water to the surface, and to reduce the laboriousness of cleaning underground water collectors.

The disadvantage of this method is the limited application.

A complex method of non-reagent wastewater treatment and sludge briquetting [3] is known, which is carried out in two stages. At the first stage, the following operations are performed: distributed discharge of water into the receiving section of the sump, in which suspended particles and immiscible liquids are separated by a density higher and lower than the density of water, accumulated and retained suspended particles and immiscible liquids with a density higher than the density of water at the bottom of the sump; suspended particles and immiscible liquids with a density higher than the density of water are precipitated intensively to the bottom of the sump in subsequent sections; conduct physical and electrical processing to intensify the deposition of contamination on sequentially installed clarifiers, located along the length of the sump with mechanized unloading of settled sludge with a scraper dewatering conveyor into the mixer, to which a binder, filler and neutralizer are added, mixed and subjected to compression, and the resulting briquettes are disinfected in microwave ovens. At the second stage, which is implemented sequentially by a number of technical devices, additional physical and electrical treatment of water, sedimentation of suspended particles, aeration and ozonation of water, collection of sludge deposited in the devices, which are sent to the dewatering part of the scraper conveyor, are carried out.

The disadvantages of the integrated method are the large capital and operating costs, the complexity of the design and large dimensions of the equipment.
