LT3037B - Device for accumulation and treatment of rain-water - Google Patents

Abstract

Device is intended for surface discharge treatment. The invention aims to increase the efficiency of accumulation and water-treatment devices. The main point of the invention is as follows: drainage pipelines for sediment dewatering are put into the broken line bottom sinks of sections. The pipelines are interconnected and it creates a possibility of washing an empty section of drainage from the water filled one.

Description

The invention relates to liquids containing suspensions; materials, petroleum products, and can be used for surface runoff. Y

The following equipment: / is missing! Nipple / cleaning efficiency due to the periodic filling of the sections and the hydromechanical removal of sediment.

According to the technical solution / the closest is a multi-section planter with a broken bottom line for laying / drainage / tubing with filters, as well as feed; and drainage piping with fittings and inlets (USSR a.l ·. No. 962210, C02F1 / 00, 1982). '

Such a plant has operational drawbacks because the unresolved removal of non-drained sediment required for drainage of flotation as well as technical water / drainage flushing requires additional construction and operating costs.

The object of the invention is to increase the operating efficiency of the device.

This is achieved by the fact that drainage pipelines with filters are located in broken bottom-bottom depressions, which allows the sediment to be drained on site and easily removed by tillage machines. This is further achieved by the fact that the drainage pipelines are interconnected, that is. ² ·.

Allows drainage of the emptied section to be flushed with water from another filled section, which does not require the technical construction of a water pipeline and the use of utility water.

The proposed new technical solution contains another arrangement of elements and new, interrelated relationships between them, and it is through these new features that the goal is achieved.

The proposed device is shown in Figure 1, where the device is a top view; Fig. 2 is a sectional view taken along the line A-A in Fig. 1;

The unit will consist of a multi-sectional sump • / section 1 with a bottom 2 in the form of a broken line and drainage piping 3 with “backfill filters made of gravel, sand and fiberglass” in its recesses. · '?' one or more, having valves 4 and connected to one another by a common outlet pipe 5.

The unit is equipped with a feed line 6 and a purified water drain line 7.The slope entrances 8, as well as oil collection and removal facilities (not shown) are provided for the access of the tillage equipment to the sections. Other water purifiers which are not shown because they do not touch, may also be the subject of the invention.

Rainfall runoff; feed line 6 enters sections of planter 1 where sedimentation is carried out and residual petroleum products are disposed of via oil collection and removal facilities. Divided water is discharged via a purified water pipeline 7 for further purification if necessary. The remaining water below the pick-up level of pipe 7 · is removed through the filter and drainage pipe 3 until the sediment is completely drained in this section.

'

The drained sediment is removed as the soil tillage machines enter sloping entrances to the sections. The drainage of any section can be flushed from any section filled with water by opening the flush and flush section valves 4 and closing the common drain pipe 5.

Drainage of the planter's broken bottom bottom recesses drainage of the sediment, which facilitates removal of sediment from the planter and eliminates the need for additional drainage.

e Connecting drainage pipelines can be flushed by using tap water from adjacent sections and not used on technical water, which means that no additional capital injections are required and

Claims (1)

Rainwater storage and purification unit with a multi-section planter with a square line 5, bottom, drainage piping with filters, feed and outlet piping with fittings and entry sections, characterized in that the drainage piping is located in the recesses of the rectangular bottom and interconnected.
