Description

The utility model relates to the field of construction and can be used to drain and treat surface runoff of rain, melt and irrigation water from roads, railways, from built-up areas, industrial sites, etc.

A known system of drainage and surface runoff cleaning, including a drainage collector, a settling chamber, a separation chamber with an inlet, outlet and side outlet of the liquid to be cleaned, a filter chamber and a discharge manifold (SU 1776636 A1, C02F 1/00, C02F 5/10 11/23/92. )

The disadvantages of the known system of removal and treatment of surface runoff is the complexity of its design due to the presence of a large number of mechanical components that increase the likelihood of failure, and lower quality of wastewater treatment.

A known system of drainage and surface runoff cleaning, including waterproofing from the surrounding soil, successively communicated between a drainage collector, a settling chamber, divided into two sections of coarse and fine cleaning, respectively, a biological pond, consisting of a shallow bioplate and a deep-sea basin, located behind the last filter chamber separated from it by a filtering dam and a discharge manifold (RU 2137884 C1, 02.25.99. IPC 6 Ε03F 1/00).

The disadvantages of the known system of removal and treatment of surface runoff is that when the surface runoff flows through the bottom bypass into the fine section of the settling chamber, it becomes clogged and the remaining impurities of the surface runoff through the spillway crest, without filtering, fall into a shallow plateau. In addition, the overflow of surface effluents from the settling chamber to the biological pond occurs through the drainage, water-discharge channels and the drainage tray, which complicates the design of the drainage and treatment system and reduces the quality of surface water treatment.

The closest is the system of drainage and treatment of surface runoff, including water-insulated from the surrounding soil, successively communicated between a drainage collector, a settling chamber, divided into two sections of coarse and fine cleaning, respectively, a biological pond, consisting of a shallow bioplate and a deep-sea basin, located after the last a filter chamber, separated from it by a filter dam, and a discharge manifold, characterized in that it is equipped with additional filter chambers Here, one of which is placed in the settling chamber between the coarse and fine sections, and the other is in front of a shallow bioplate, each of the additional filter chambers made of filter materials laid in layers from top to bottom, with a decrease in the filtration coefficient of each subsequent layer relative to the previous one, while the coefficient the filtration of each layer of the chamber is not less than 1 m / day, and in the additional filter chambers their vertical walls and one of the upper layers are made of gabions and covered with morning geotextile side, as well as an additional filter system is equipped with a dam, installed in the biological pond between shallow bioplato and plunge pool (RU 2200802, E03F 1/00, C02F 1/00, 20.03.2003).

The disadvantages of the known system of drainage and treatment of surface runoff is that during the flow of surface runoff, the settling chambers clog it and the remaining impurities of the surface runoff through the crest of the spillway, without filtering, fall into a shallow plateau and the design of the drainage and sewage treatment system is complicated, which reduces the quality cleaning up.

The technical result of this utility model is to simplify the design and improve the quality of surface water treatment.

The technical result of the utility model consists in the fact that the drainage and surface drainage system, including those isolated from the surrounding soil, sequentially interconnected by a drainage collector, a settling chamber, divided into two sections of coarse and fine cleaning, respectively, a biological pond consisting of a shallow bioplate and a deep-water basin, located behind the latter, a filter chamber separated from it by a filter dam, and a discharge manifold equipped with additional filter chambers, one of which is placed in the settling chamber between the coarse and fine sections, and the other is in front of the shallow bioplate, with additional filter chambers made of vertical walls and filter materials laid in layers from top to bottom, with a decrease in the filtration coefficient of each subsequent layer relative to the previous one, when this filter coefficient of each layer of the chamber is not less than 1 m / day., and the vertical walls of the additional filter chambers are made of plastic frame and are covered with electric a fictitious tubular knitted fabric.

The implementation of the vertical walls of the additional filter chambers from a plastic frame covered with elastic tubular knitwear for weaving fangs provides additional cleaning of the surface drain from solid particles and suspensions, which increases the quality of the filter.

In this case, the execution of the vertical walls of the additional filter chambers from a plastic frame covered with elastic tubular knitwear for weaving fangs, as the pores of the elastic tubular knit become dirty, it can be easily removed from the vertical walls and regenerated by changing the pore structure of the elastic tubular knitwear (under tension).

The plastic frame in combination with elastic tubular knitwear for weaving fangs allows you to simplify and simplify the design of the filter chambers while maintaining their strength.

Figure 1 presents a diagram of the drainage and cleaning of surface runoff, figure 2 shows the design of the filter chamber, and figure 3 shows a graphical record of an elastic knitted fabric weave fangs.

Figure 1 presents a system of drainage and treatment of surface runoff, which includes a drainage collector 1, a settling chamber 2, divided into sections of coarse 3 and fine 4, respectively, a biological pond, consisting of a shallow bioplate 5 and deep-water basin 6, a filter chamber 7, separated from the deep-sea basin by a filter dam 8, and a discharge manifold 9. The system for the removal and cleaning of the surface layer is equipped with additional fi liter chambers 10 and 11. The filter chamber 10 is installed in the settling chamber 2 between the coarse 3 and fine 4 cleaning sections, and the filter chamber 11 is installed in front of the shallow bioplate 5.

An additional filtering dam 12 is installed between the shallow bioplate 5 and the deep-sea pool 6.

Figure 2 presents the design of additional filter chambers 10 and 11, which are a plastic frame 13 covered with tubular elastic knitwear 14.

As the material of the plastic frame, polypropylene (PP) or copolymers of propylene, low pressure polyethylene (HDPE), polyethylene terephthalate (PET) or other plastic with sufficient strength and low toxicity are used.

Figure 3 presents a graphical record of an elastic tubular knitted fabric of weaving fangs - two knitted rows. Each row consists of simultaneously knitted in the loops of normal tensile 15 and elastomeric threads 16, drafts 17 of the same threads of normal tensile 15 and elastomeric threads 16.

At the same time, in the front row: loops of ordinary tensile threads 15 and elastomeric threads 16 are knitted on the rear needle bar 18, and the same threads 15 and 16 are made on the front needle bar 19; in the next row, on the contrary: the outline on the rear needle bar 18 of ordinary tensile threads 15 and elastomeric threads 16, and on the front needle bar - from the same threads 15 and 16, loops are knitted. Next, the rows alternate in the same order.

Elastic tubular knit fang knitwear is made by simultaneously knitting yarns of ordinary tensile strength 15 and elastomeric yarns 16 into loops on a double-loop circular knitting knit machine of class 22 by tensioning yarns of normal tensile strength 28-32 N fed into the loop-forming system, and elastomeric yarns 16-22 H, according to the method “Without conclusion” by setting the closing wedges in the cylinder in even loop-forming systems to the “incomplete conclusion” position, and in the rippshaybe in odd systems. The strength and bulkiness of the knitted fabric increases due to loop arches and loop sticks of the loop frame and drafts of ordinary tensile threads.

The system of removal and treatment of surface wastewater (rainwater, melt water, etc.) works as follows.

Surface runoff of rain, washing or melt water from the drainage section flows to the water supply collector 1 and flows by gravity to the coarse cleaning section 3 of the settling chamber 2, where it is freed from large mechanical impurities. Next, the surface drains are filtered through an additional filter chamber 10, which is a plastic frame 13 made of polypropylene or propylene copolymers (other plastics such as HDPE, PET, etc. can also be used) fitted with elastic tubular knit 14 and filled with layers of natural filtering material, and get into the fine cleaning section 4 of the settling chamber 2. When the drains pass through the layers of natural filtering material, additional filtering chambers and gabions of their vertical walls purification of effluents from suspended particles and associated petroleum products occurs. The coefficient of filtration of natural filtering material, filled in layers, should be at least 1 m / day, which ensures maximum performance of the treatment plant of this type.

The use of filtering filling with a lower value of the filtration coefficient will lead to a decrease in the productivity of the treatment plant and will require a more frequent change of filtering material.

In the fine section, fine impurities are deposited. From the fine-cleaning section, surface effluents are filtered through an additional filter chamber 11, which is also a plastic frame 13 made of the same materials, covered with elastic tubular knit 14 and filled with granular natural material with a filtration coefficient of at least 1 m / day, and enters shallow bioplate 5.

A shallow bioplate is a basin planted with higher aquatic plants (macrophytes) of one or several species: reeds, cattail, reeds, sedges, and pond. In a shallow bioplate, biodegradation of petroleum products contained in surface runoff occurs, compounds and ions of heavy metals bind. The thickness of the water layer in a shallow bioplate above the ground should be at least 30 cm. From a shallow bioplate, surface runoff flows through an additional filter dam 12, made of gabion structures, into a deep-water pool 6 with a depth of at least 1 m. Anaerobic processes occur in the deep-water part of the bioplate decomposition of the organic matter of effluents and oxidized derivatives of petroleum products, as well as the binding and accumulation of compounds of heavy metals. In addition, biological filtration of wastewater by zooplankton organisms occurs in the water column.

From the deep-sea part of the bioplate, water, filtered through a gabion filter dam, enters a full-flow filter chamber 7 filled with a natural sorbent, where the surface runoff is treated. The cleaned surface drain from the filter chamber is discharged along the discharge collector 9 to the topography or to the reservoir.

In case of contamination of the elastic tubular knitwear, it is removed from the plastic frame, stretched to increase the pore size and regenerated by washing with a reverse current of water.

Thus, the implementation of the vertical walls of the additional filter chambers from a plastic frame covered with an elastic tubular knitted fabric of weaving fangs simplifies the design of the drainage system and surface runoff cleaning and improves the quality of the cleaning.
