Abstract

This invention relates to the biological treatment of domestic waste water based on the attachment of microorganisms to glass fiber loading. The purpose of the invention is to increase the reliability of the device and reduce operating costs due to the use of natural hydrostatic energy of natural or artificial reservoirs. The device consists of a rectangular tank 1 with water to be cleaned and two glass-loading units 2 interconnected by two coaxial articulated parallelograms 4. The device contains two rectangular tanks 5, each of which has a bell type discharge valve 6 and in which nozzles 14 from a reversible tray 9, kinematically connected with vertically moving glass-glasses, enter. Under the force of gravity of the water flowing from the reservoir 23, the container 5 together with the block 2 is lowered. In the lower position, the valve 6 is activated, water is poured out from the tank 5. At the same time, tray 9 switches over due to the displacement tg 12, the water begins to flow into the tank 5, which is in the upper position. The cycle is repeated. The device can reduce operating costs and increase plant reliability. 1 silt, and fJ (L from 4 00 with SP about:

The invention relates to the biological purification of stationary waters on the basis of the attachment of microorganisms to a glass-finisher load, made in the form of a ruff-type cord, and can be used in rural areas in settlements where there are water bodies with hydrostatic drop of water relative to the water flow; | t; graded landscape line of the area e less than three meters, I The purpose of the invention - the increase by | Efficiency of operation of the device and reduction of operating costs due to IF 1 using natural hydrostatic energy of natural or 1 artificial water bodies. : The drawing shows a general view of the device in the intermediate-position (working condition state).

ruff biomass. The weight of the water in the tank must be equal to the maximum biomass, filling it with a block out of the water. All other moving parts of the stack are weighed by the symmetry of the hinge parallelogram. The biomass of the glass-ruff unit immersed in the water is balanced by extrusion by force.

The device works the next time.

In the mode of use of natural hydrostatic energy, vent-circuit 1 is closed and valve 16 is open. Due to the difference in the hydraulic pressure, water from gate 23, through gate 21, which provides the required mass flow rate, enters pr. 20 intermediate tank 20, and from it to tray 9, which is in one of the extreme positions (turned relative to vertical). axis or ow in or to the right).

ruff biomass. The weight of water in the tank should be equal to the maximum weight of the biomass by filling it with a block out of the water. All other moving parts are balanced due to the symmetry of the hinged parallelogram. The biomass of a submerged block of glass is balanced by the buoyancy force.

The device works as follows.

In the mode of using natural Hydrostatic energy, vent 17 is closed and valve 16 is open. From the reservoir 23, due to the difference in the hydraulic pressure, water through the valve 21, which provides the necessary mass flow, enters the intermediate tank 20, and from it into the tray 9, which is in one of the extreme positions (turned relative to the vertical axis). left or right). From tray 9 water by

wide parallelograms 4. These ke racks are rigidly attached to rectangular containers 5, which have bell-type exhaust valves 6, with pushers 7 resting in the Lower position at the bottom of the drainage tray 8. Positions 2–8 are located symmetrically relative to the vertical the axis of the working capacity, the passage through the middle of it.

Above the level of rectangular containers 5, a reversible tray 9 is installed, which is capable of turning around sharira 10 and having a double-arm lever 11, which is connected with the blocks of the glass coupler 2 by means of tubes 12.

Under the tray 9 is installed chute 13, at the ends of which are dressed flexible nozzles 14, lowered by the ends in the tank 5.

Drainage trays 8 are interconnected by a pipeline 15 having a valve 16 through which water can escape into the surrounding space, and a valve 17 connected to a pumping station 18 connected by pipeline 19 with an intermediate tank 2Q7. The valve 21 and pipe 22 connect an intermediate tank 20. with a reservoir 23. The device has an inlet 24 and an outlet 25 of the treated water.

The dimensions of the tank 5 are determined from the conditions of the system's motion with maximum filling of blocks g, glass

It flows into one of the containers 5, which, under the action of gravity of the incoming water, begins to descend. Together with it, the glass-case block is lowered, immersed in cleared water. At the same time, another tank and another block of glass windows are raised.

A container 5 with a necessary (adjusted) advance by the pusher 7 of the valve 6 rests on the bottom of the tray 8. The valve opens and releases water from the container 5. Due to the fact that it is made in the form of a bell, the air is pushed out holding it open until the container is completely empty. The water dispensed from the tank enters the drainage tray 8 and

through the valve 16 goes into the surrounding space.

Simultaneously with the actuation of the valve 6 due to the movement of the pull g 12 there occurs a reversal of the tray 9, as a result of which the water begins to flow.

top position. As a result of its filling with water under the action of the force of gravity of the latter, it begins to fall.

Further cycles are repeated.

When operating in the pumping station use mode, the valve 16 is closed, and the valve 17 is opened. R

In this case, water is pumped from the drainage trays 8 into the intermediate tank 20 with the help of a pump. The rest of the device is similar.

The use of natural gas hydrostatic energy of reservoirs in the device leads to a decrease in operating

costs and increase the reliability of working flexible with the blocks from the glass of the installation.
