Abstract

The invention relates to the purification of the switch of the dode 819 waste water of the ow and allowing and increasing the device ar 1-, separating the intake 3 lower part of the door 5. The mixing pan 7 discharges the concentrate position 11 and discharges the latter to the water. The signal pump 7 at the level and from it level of the contaminated and open concentrate turns on the waste water of livestock breeding complexes and allows to reduce energy consumption and improve the quality of water purification. The device contains a receiving tank 1-, divided by a partition 2 into the intake 3 and settling 4 chambers. There is a door 5 in the lower part of the partition 2. A mixing pump 6 is installed in chamber 4, in chamber 3 there is a pump 7, a level indicator 8, a concentrator 9 and a door position indicator 10. There are inlet 11 and outlet 12 pipelines, the latter is equipped with a water switch. The 8 level alarm device turns on the pump 7 when the water reaches the upper level and shuts it down when it reaches the lower level. When the level of water pollution exceeds a predetermined level and the door 5 is open, according to commands from the concentrator 9 and the alarm 10, the pump 6 is turned on. 1 sludge.

Description

The invention relates to wastewater treatment, in particular, to systems for managing the primary separation of wastewater from livestock breeding complexes, and can be used in agricultural, industrial and municipal sewage treatment plants.

The purpose of the invention is to reduce energy consumption and improve the quality of water purification.

The drawing shows the proposed device.

The device contains a receiving tank 1, divided by a partition 2 into the intake 3 and the settling chamber 4. In the lower part of the partition 2 there is a door 5. The device also contains a mixing pump 6 in the settling chamber 4, a pump 7, a liquid level gauge 8 and a concentrator 9 suspended solids, a door position indicator 10, a supply pipe 11 and a discharge pipe 12 with a water switch (not shown).

The device works as follows.

Pipeline 11 in the lower part of the intake chamber 3 of the receiving tank 1 receives waste water. The pump 7 pumps through the pipeline 12 the incoming wastewater to the subsequent purification facilities. The pump 7 controls the level indicator 8, which turns it on when the liquid reaches the upper level and turns off when the level drops to the minimum level. Simultaneously with the pump 7, the mixing pump 6 can work if the door 5 is open and the degree of water pollution in the chamber 3, controlled by the concentration meter 9, exceeds the set one.

If the supply of the original waste water

exceeds the capacity of the suction pump 7, the water begins to overflow through the partition 2 in the

a standing chamber 4. In the latter, the sedimentation of suspended particles, which accumulate in its lower part, occurs. The pump 6 is turned on by the signals of the concentrator 9 High pollution of the water and the alarm 10 The door is open and mixes the sediment. As the flow of water through conduit 11 decreases and the sediment from the settling chamber 4 is partially removed and more pure water flows through the door 5 in the partition 2, a moment comes when the degree of contamination of water below the threshold of the concentrator 9 and the last signal the pump 6 is shut off. The concentrator 9 is also connected to a water switch on the outlet piping, which allows the separation of strongly and weakly contaminated sewage by supplying them to different treatment plants. Invention Formula A device for automatic control of primary sewage separation, comprising a receiving tank with intake and settling chambers, separating their overflow partition with a door in the lower part, a mixing pump installed in the settling chamber, and a suction pump connected to the discharge pipeline and connected to The sensor in the settling chamber, characterized in that, in order to reduce energy consumption and improve the quality of water purification, it is additionally equipped with a suspension meter of suspended solids p intake chamber and a door position indicator associated with the stirring pump, as well as a water switch on the discharge pipe, wherein the switch is connected to a concentrator.
