The storm water drainage system

 

(57) Abstract:

The invention relates to the protection of waters, in particular to the prevention of pollution of surface waters by rain water, which is diverted from the urban area. The goal is to simplify the design and improve the quality of wastewater treatment. The technical result is achieved by the fact that the system of storm water drainage, including take rain pit wells, collector probatova sewers and collector drainage of rain water in the reservoir, provided with a tank for sewage treatment, divided into reception, an overflow, a settling chamber and a chamber for collecting oil, while settling chamber is connected to the collector probatova sewage sludge pipeline, includes side sawtooth Weir separating the intake chamber from settling, the camera for collecting petroleum products equipped with float valves at the inlet and mine discharge at the outlet from the chamber; the system is supplemented filter stone prism installed at the outlet of the tank. 5 Il.

The invention relates to the protection of waters, in particular the prevention of pollution of surface waters by rain water, which is diverted from the urban area.

In the amount of garbage products of demolition and soil settled emissions from road transport, industrial processes, petroleum products. The intake of these substances in water bodies leads to blockage, deterioration of the oxygen regime and organoleptic characteristics of water.

A device for separation of liquid light and heavy fractions. C. Germany 2848629, class E 03 F 5/16, 1980), contains a partition dividing it into chambers for the deposition of solid fractions and collect on the surface of the light fractions, followed by taking them to the outside of the device.

A disadvantage of the known device is that it cannot be applied for wastewater treatment due to the lack of output of clean water.

Most similar to that proposed by the technological nature is a system of storm water drainage.with. USSR N 1142607, class E 03 F 5/10, 1983), containing take rain pit wells, collector probatova sewers and collector drainage of rain water in the reservoir, provided with a reservoir for cleaning streams containing vertical septum, which divides it into reception, overflow and sucky camera, and the settling chamber is connected to the collector probatova sewage sludge travoprost large sizes. In addition, through a tank of water purification are not all rain water, which makes it possible to discharge into bodies of water pollutants. Operation structures complicates the presence of valves, floats, hooks, etc. in Addition, part of the rainwater runoff containing petroleum products, after filling of the receiving chamber may be discharged without treatment into the pond.

The technical solution is simplifying the design and improving the quality of wastewater treatment.

The task is achieved by the fact that the system of storm water drainage, including take rain pit wells, collector probatova sewers and collector drainage of rain water in the reservoir tank for sewage treatment, divided into reception, an overflow, a settling chamber and a chamber for collecting oil, while settling chamber is connected to the collector probatova sewage sludge pipeline, characterized in that it has lateral sawtooth Weir separating the intake chamber from settling and Luggage for collecting petroleum products equipped with float valves at the inlet and mine discharge at the outlet from the chamber, the system includes filter stone prism, installed at the outlet of the tank for sewage treatment.

ravnomernoe distribution of water flow in the settling chamber, float shutter allows you to skip to the camera for collecting oil water layers containing petroleum products, and maintains the water level at the entrance to the chamber 4 mm, which prevents the outflow of oil through the mine discharge, which in turn ensures the pass of the settled water without oil from the chamber for collecting oil in the overflow chamber, filter stone prism prevent streambed scour pond discharged waste waters and acts as a filter that increases the degree of purification facilities in General.

According to the patent and scientific literature not found a similar technical solution that allows to judge about the level of invention proposals.

The invention is illustrated by drawings, where Fig. 1 shows a General view of the rainwater drainage system of Fig. 2 - section a-a in Fig. 1 (cross-section of the tank and filter stone prism), Fig. 3 - tank effluent in Fig. 4 - section b-b of Fig. 3 (a camera for collecting oil), Fig. 5 - section C-C in Fig. 3 (camera to collect suspended solids).

The rainwater drainage system includes take rain pit wells 1, located in a catchment area is obscene with the tank for wastewater treatment 4, at the outlet of which is located a filter stone prism 5.

The tank 4 contains side sawtooth Weir 6, which divides it into reception 7 and 8 sucks the camera. Also the tank 4 contains a vertical wall 9, which separates the overflow chamber 10. Settling chamber 8 contains a vertical partition 11, which separates the chamber for collection of suspended solids 12.

Tank 4 also contains a chamber for collecting oil 13, provided with a floating gate 14 and shaft outlet 15.

Receiving chamber 7 includes overflow hole 16 for the passage of the maximum water flow in the overflow chamber 10 that contains perforated wall 17.

The bottom of the settling chamber 8 is made with a bias towards educated in the bottom chamber of the collection of suspended solids 12 sludge sump is attached to the slurry pipe 18 having a valve 19, the other end of the slurry pipeline 18 is attached to the observation well 20 collector 2 probatova sewage.

Tank for wastewater treatment 4 topped with plates, some plates are equipped with a removable sealed hatches.

The rainwater drainage system works as follows.

the s 1 and from them through pipelines into the collector 3 drainage of rain waters, by which waste water fall through the manhole 21 by two pipelines in the tank for wastewater treatment 4.

Untreated water enters the receiving chamber 7, in which there is a transition of the flow of water from the turbulent condition in the calm. From the inlet chamber 7 through the side of the sawtooth Weir 6 water shimmers in the settling chamber 8, in which there is loss of sediment. The oil emerges at the surface of the settling chamber 8, proceed by gravity into the chamber for collecting oil 13 through the floating gate 14, a constant water level in the Weir - 4 mm From the chamber 13 of the settled water without oil through the shaft outlet 15 flows into an overflow chamber 10.

At the end of the settling chamber 8 is provided with a vertical wall 11, which delays the removal of oil and water from the bottom gets in the chamber for collecting suspended solids 12, which contains a pit. From the chamber 12 through the vertical wall 9 purified water flows into an overflow chamber 10. The water transit through perforated wall 17 and filter stone prism 5 flows into the reservoir 22.

The proposed system storm drainage will significantly reduce the amount of beginning the mA rainwater drainage, including take rain pit wells, collector probatova sewers and collector drainage of rain water in the reservoir tank for sewage treatment, divided into reception, an overflow, a settling chamber and a chamber for collecting oil, while settling chamber is connected to the collector probatova sewage sludge pipeline, characterized in that the system has a side sawtooth Weir separating the intake chamber from settling and Luggage for collecting petroleum products equipped with float valves at the inlet and mine discharge at the outlet from the chamber, the system includes filter stone prism mounted at the outlet of the tank for sewage treatment.
