Description

The invention relates to the field of wastewater treatment, in particular, to devices for controlling the primary segregation of wastewater from livestock breeding complexes, and can be used in agriculture as well as in industrial use of valuable impurities from wastewater. The aim of the invention is to reduce power consumption and increasing degree

water treatment .- .;

Fig; 1 shows a diagram of the device; FIG 2 is a functional block diagram of the control unit.

The intake chamber of the receiving tank 2 is used to receive waste water. The suction pump 3 is pumped over. It goes to the separator 4, where coarse impurities are released, which are conveyed by the conveyor system 5 to the vehicles 6 and then transported to the floor (to quarantine platforms). Separated from coarse impurities, waste water is collected in primer h 7, from where it is supplied by pumps 8 and feed respectively to the sludge tank 10 or ne primary vertical sump 11 Counters 12 and 13 control the number of working hours per day of pumps 8 and 9, respectively, mounted in settling chamber 14 the receiving tank 2, the bubbling pump 15 mixes the liquids there; and d) the tank (to remove it) at the moment of waste water disposal into the silo reservoir 10, controls the process of fading 16 controls. The level of the liquid in the receiving tank 2, in mark 7 and the level of the sump in the sump 11 are controlled respectively by level gauges 17-19. A partition 20 with a door separates the intake 1 and the settling chamber 14 of the receiving tank 2. The concentrator 21 controls the degree of contamination of the waste water, for example, by: its optical density proportional to the content of suspended matter in the waste water. conduit 22 equipped with an electrified gate.

The control unit 16 (FIG. 2) contains a timer, a timer 23, a divider 24, a comparison element 25, a dial 26, a regulator 27, a threshold element 28 and a switch 29 o

The management of the process of primary wastewater separation is carried out as follows.

With a sufficient level of wastewater in the receiving tank 2, controlled by the level gauge 17, the pump 3 is pumped out of the wastewater to the separator 4o. If the flow of wastewater into the intake chamber 1 exceeds it. the flow rate, the collecting chamber 1 is overfilled and the water is poured over the water. the partition 20 into the settling tank 14, otherwise the water level in the intake chamber 1 is lowered and water from the settling basin r: ame 14 through the valve in the lower part of the partition 20 When the receiving tank 2 is completely pumped out by the level indicator G / pump 3

In the separator, 4 drains are separated from the coarse suspension.

The degree of contamination of wastewater in Primka 7 during the day varies significantly. The pumping of effluent from Primer 7 into the silo reservoir 10 is carried out when the concentration of suspended solids in them exceeds the set value. the sludge tank 10, as well as the pump 15, which barges the waste water in the settling chamber 14 of the receiving tank 2 °. If the concentration of contaminants in the waste water is less than the installed one, the pump 9 will supply the wellness to the settling tank ki 11 of

Adjustment to a predetermined threshold of operation of the concentrator 21 is carried out manually and corrected automatically with respect to the volumes of wastewater supplied for a certain period of time (1-7 days) for cleaning and c. sludge tank VO avoid feed to the last: too much. A small or too large amount of wastewater. In the first case, there is an under-utilization of the production capacity of the sludge accumulator and a decrease in the overall quality of treatment, since additional masses of significant contaminated waste water are supplied to the purification, in the second case, the preconditioning filling of the accumulator with low-concentration waste water As a result, the cyclical operation of the sludge tanks is disrupted, which may cause environmental pollution.

The control unit 16 performs the correction of the response threshold of the concentratometer 21 as follows, (FIG. 2);

Counters 12 and 13 count the volume of wastewater, fed respectively to the silo reservoir 10 and to the sump 11 during the period of time specified by the timer 23, the first output of which is connected to the third (gating) divider input. After this time, the signals from counters 12 and 13 are applied to the first and second inputs

the divider 24 and further on the comparison element 25 The signal from the setting device 26 comes here, and a signal equal to the difference of the input signals is generated at the output of the comparison element. This signal goes to the regulator 27, and from its output to the first input of the threshold element 28, changing accordingly its threshold. On the second

the input of the element 28 receives the signal of the concentrator 21 and, if it is below the response threshold, the switching unit 29 connected at the output of the threshold element 28 disconnects the signal to turn on the pump. 9 If the signal of the concentrator 21 exceeds the response threshold of the element 28, the switch 29 sends a signal to turn on the pumps 8 and 15, the counters 12 and 13 reset also by the signal of the timer 23

(

If, for example, over a week in Ilona: support 10 receives too much wastewater, then regulator 27 will increase the response threshold by one step and during the next week a smaller amount of wastewater will enter the sludge tank.
