Abstract

1. DEVICE FOR CLEANING WASTE WATER, including a body with a conical bottom, divided by a vertical partition with a bottom hole in the receiving chamber with liquid and a chamber, with a perforated partition on which the filter element is located, supplying the nozzle of the water to be purified and the discharge pipes of the clarified water and sediment It is distinguished by the fact that, in order to increase the cleaning efficiency, it is equipped with a device installed in the receiving chamber for collecting splashes and a cylinder, the upper edge of which olozhena below the liquid level, drainage chute -c conductive perforated wall adjacent to filtruk DeMouy element, wherein the inlet nozzle mounted tangentially treated water in the bottom of the cylinder. 2. The device according to claim 1, wherein the filter element is designed as a removable mesh box with granulated polyethylene mounted on a perforated partition.

Description

The invention relates to the purification of industrial wastewater, namely, the treatment of wastewater from suspended matter, and is intended primarily for the treatment of wastewater from the production of recycled polyethylene, where wastewater is discharged with a high concentration of suspended particles in the form of soil, sand and crushed polyethylene.

A device for natural and wastewater clarification is known, comprising a horizontal rectangular housing with a bottom, separated by two internal vertical walls with guide walls, high-speed filters with flotation chambers located above them, distribution pipelines of clarified water and water-air solution, a collection of wash water and Foam collectors C13.

A disadvantage of this device is its excessive bulkiness and complexity, which consists in the presence of numerous units of the device, which creates inconvenience in operation and increases the cost of water purification.

The closest to the proposed technical and corrosive essence and the achieved result is a device for wastewater treatment, including a housing with a conical bottom, divided by a vertical partition with a bottom hole in the receiving chamber with liquid and a chamber with a perforated partition on which the filter element is located. purified water and nozzles for drainage of clarified water and sediment 2}.

A disadvantage of the known device is the low cleaning efficiency due to the absence of the pop-up contaminant removal unit and the inconvenient placement of the unit for the removal of precipitated sediment.

The purpose of the invention is to increase the cleaning efficiency,

The goal is achieved by the fact that a sewage treatment device, comprising a housing with a conical bottom, divided by a vertical partition with a bottom hole in the receiving chamber with liquid and a chamber with a perforated partition, on which the filter element is located, supplying the nozzle of the water to be purified and the discharge pipe of the clarified water and sludge is equipped with a device for collecting populating substances installed in the receiving chamber and a cylinder, the upper edge of which is located below the liquid level, water a lead-in tray with a perforated wall adjacent to the filter element, while the inlet pipe of the treated water is installed tangentially in the bottom of the cylinder.

It is advisable to make the filter element in the form of a removable mesh box with granulated polyethylene mounted on a perforated partition.

FIG. Figure 1 shows schematically the proposed device for cleaning, waste water, a plan; in fig. 2 shows section A-A in FIG. one.

The device includes a horizontal rectangular housing 1 with a cone-shaped bottom 2 and a nozzle 3 for draining sludge. The housing is divided by a vertical partition 4 with a bottom opening 5 into a receiving chamber 6 and a filtration chamber 7 with a perforated partition 8 on which the filtering element 9 is located, made in the form of a removable mesh box 10 with granulated polyethylene 11. The primary camera 6 has a fixture located at the top 12 to collect supernatants and a cylinder 13, the upper edge of which is located below the liquid level. The cylinder 13 has a supply pipe 14 of the water to be purified tangentially installed in its bottom part and a pipe 15 for removing sediment. On the wall of the housing 1, adjacent to the filter element 9, is placed a drainage tray 16 with a perforated wall 17 and a branch pipe 18 for discharging clarified water. The mesh box 10 has a perforated cover 19, with which the filtering load 11 is closed on top, which prevents its separation during filtration.

The wastewater treatment device operates as follows.

Purified water through the pipe 14 is fed into the cylinder 13, placed in the receiving chamber 6. Since the pipe 14 is installed tangentially in the bottom of the cylinder 13, water flows into its lower part and at the same time receives a directional movement upwards, which creates in the cylinder 13
