Abstract

The invention relates to the construction of biological wastewater treatment plants and can be used in water treatment systems of small settlements. The purpose of the invention is to increase the cleaning efficiency by ensuring an even supply of effluent, reducing capital investments and energy costs. The apparatus contains chambers 1,2 and 3 of biocoagulation, primary sedimentation and averaging. Using the float device 4, the effluent is uniformly supplied to the aeration chamber 8 connected to the secondary lag chamber 10. The original wastewater is supplied to the biocoagulation chamber 1, where it is subjected to pre-aeration with the addition of sludge from the secondary settling zone. Through the float device 4, the waste water enters the aeration chamber 8 and is discharged from the plant through the secondary settling chamber 10. The invention makes it possible to increase the reliability and efficiency of wastewater treatment while at the same time reducing power consumption, material consumption and operating costs. 1 il.

Due to the fact that the flexible nozzle 5 of the float device is attached through a rigid rod 7, a certain column of liquid is formed above its inlet, and a constant pressure is created in the exhaust pipe that ensures even removal of fluid from the averaging chamber 3 to the aeration chamber 8. The float 6 freely moves (located in the zone of the settling tank). When the liquid level drops to 3.20 m, the flow is stopped automatically and sewage sludge in the aeration tank 8.Obem zone located below 3.20 m remains unchanged and corresponds to the estimated time required for effluent clarification.

Aeration chamber 8 is designed as a classic aero tank. The mixture of wastewater and activated sludge from the aeration chamber enters the secondary settling chamber 10. In order to trap particles of sludge with air bubbles, the waste water before entering the secondary sedimentation zone passes through: the dehumidification chamber 9. In KaHCfii, second secondary (upholding occurs, separation of sludge and biologically purified waste liquid is given.

Taking into account that the installation is intended for DPN of rural objects, the flow of water from which differs not only in large irregularities in the inflow, but also in the concentration of contaminants, the presence of a bio-coagulant allows the operation of facilities in various modes: WPC-turn on the supply of air and excess sludge Q bio-coagulant, with a decrease in concentration - turn off, while all excess active sludge is fed into the chamber 12 of aerobic stabilization.

Investigations carried out at the existing sewage treatment plants have established that the capacity of the averager can be taken in the amount of 10% of the daily performance of the facilities.
