Description

The invention relates to the field of water supply, and is intended for the collection of water from surface water sources and its preliminary treatment in the channel of a watercourse.

A water treatment plant is known which comprises a cylinder flooded in a source under a water level with an open bottom, a covered net and a lid, inside which a thin-layer sump, a filter with a floating charge, and a production pipe with a pump and holes for receiving the filtrate are placed (put , decision on application No. 4809520/33 dated 5.03.90).

However, such a construction does not exclude the need to build a special clean water tank and an installation for its disinfection on the shore, and complicates the operation of a complex of water intake, treatment and storage facilities.

The aim of the invention is to expand the functions of the designation of the structure and simplify operation. The goal is achieved in that the structure is additionally equipped with a clean water pressure tank located between the pump lifting pipe and the water conduit, a bactericidal installation for disinfecting the water is mounted inside the tank, and an automatic pump and bactericidal control unit is installed on its outer side surface.

The drawing shows the proposed structure.

It consists of a water treatment unit made in the form of a thin-layer sedimentation tank 1 and a filter with a floating charge 2 with a receiving chamber 3 of a filtrate, an electric submersible pump 4, a pressure tank 5 of clean water with a bactericidal lamp 6 inside it, an automatic control station 7, and a pressure head a water conduit 8 connected to a removable lid of the tank 9, a water outlet h СО О 00 00

Guy of the water tower and pontoon platform 10.

The construction works as follows.

According to the signal from the time relay of control station 5, a pump 4 is turned on, which, taking water from the chamber 3, ensures the forced passage of water from the water source, first through the mesh 14 and a thin-layer sump 1, and then the filter 2. 10 Purified water through a perforated surface the top of chamber 3 is assembled inside the chamber. When the pump is running, resistance is overcome in the grid, sump and riser. The pumped water is supplied to the tank 5 by pumping it with a pump 15, where it is disinfected with bactericidal lamps 6, and then water consumers are located along the water supply system 8 and the distribution network located along the regulating circuit. Reservoir 6 is designed as regulating and reserve, which makes it possible to even out uneven water consumption and water supply, as well as to store the water supply in case of fire. At the end of the filter cycle with 25 set duration, the relay of control station 7 gives a command to simultaneously turn off the electric pump and bactericidal lamps for 5-6 minutes. After that, due to the excess pressure of water 30 inside the pressure tank over atmospheric, water from the network and the tank returns to the chamber 3 by a reverse current, and from there through the holes of the mesh to the top of the filter 2.35

Rushing from top to bottom, pure water expands the floating load, while washing away the pollution from the load, sump and mesh into the channel of the watercourse.

At the end of the flushing with “adank 40”, the time relay of station 7 gives a command to turn on the electric pump and bactericidal lamps. The cycle of water intake, treatment, disinfection and water supply to consumers is repeated. For the 45th shutdown period, the network is supplied with water from a water tower.

An analysis of patent information confirms that the distinguishing features are significant.

A comparative analysis of the known and declared structures shows that when the latter is introduced, its functions are expanded, the costs of construction and installation of a clean water tank on the shore are reduced, the compactness, manufacturability of the installation is increased, the connecting pipelines of the piping are reduced, and there is no need to build collection facilities and purification of wash water and disposal of sludge from a water treatment unit onshore, the number of operating personnel is reduced, the construction is fully automated Wan. The reliability of fish protection is improved.

The degree of water disinfection is monitored by analyzing the water taken at the starting point of conduit 8 on the shore, and a possible breakdown of the lamps or a pump malfunction is controlled by the automatic station using thermal relays and communicated to personnel by electrical or audible alarms to the control room. With such a system, the alienation of land for the construction of structures on the shore is significantly saved.

The performance of purified water and the reliability of the system are controlled by the number of water intake-treatment-pumping units connected to one tank.
