Khoz - domestic wastewater from the domestic premises of the reconstructed incubator 12.B.11.04.I.12.003 for OJSC "Kaluga Poultry Farm" according to the gravity network with separate 110 mm releases are discharged into the existing 200 mm sewage network passing next to the industrial incubator building.

The consumption of domestic waste water is: 2.55 m3/day; 2.61 m3/h 1.23 l/s.

Annual consumption of household wastewater by industrial incubator is: Qday = 2.55 m3/day x 365 (days) = 930.75 m3/year.

The water disposal rate per worker is 25 l/day. as per SNiP 2.04.0185 *.

The concentration of BPK5 and suspended substances in domestic wastewater is not more than 270 mg/l and 325 mg/l, respectively. The pH is in the range - 6.5 sound7.5.

The production sewage system provides for drainage from process equipment through floor siphons and floor grilles.

Drain from process equipment is provided to the existing 200 mm sewage network, passing next to the reconstructed incubator 12.B.11.04.I.12.003 for OJSC "Kaluga Poultry Farm," located at the address: the village of Leo Tolstoy, Dzerzhinsky District, Kaluga Region.

At the outlets of the sewerage network (4 points), inspection sewage wells of 1000 mm are provided, which are made of prefabricated reinforced concrete elements according to the typical design. 9020922.84

c) Description and characteristics of the water supply system and its parameters.

For the reconstructed incubator 12.B.11.04.I.12.003 for OJSC "Kaluga Poultry Farm," located at the address: the village of Leo Tolstoy, Dzerzhinsky District, Kaluga Region, the following water supply systems were designed:

combined system of domestic and potable - industrial and fire-fighting water supply B1;

hot water supply system T3;

Water cooling and humidification systems of incubation and switching-off stations AirStreamerPlus developed using Hartmann technology.

The CCSC compact central refrigeration unit is used to produce cold water for incubators and hatcheries.

A separate internal pump station with high-performance centrifugal pumps provides consumers with cooling water.

A highly efficient water cooling system with copper coils provides cooling of the incubation machine. Forced air cooling is not necessary. This allows operation of the incubation machine with cooling water from 12 to 20 0C. Flow start and stop are controlled by Danfoss solenoid valves.

Humidification is achieved by means of nozzles which spray a mixture of fine water droplets into a rotating pulsator fan. There is one nozzle per central air mixing zone. Nozzle is located in tunnels of central zone of air mixing and is connected to line of water and supply of compressed air. Operation is controlled by solenoid valves. The nozzles are self-cleaning and do not require maintenance.

The source of water supply for domestic, fire-fighting and industrial needs is the existing on-site water supply networks of 200 mm.

To connect the reconstructed building of the industrial incubator to the water supply system of Kaluga Poultry Farm OJSC, a dead end water supply from PE100 SDR 17 110x6.6 mm polyethylene pipes is designed according to GOST 185992001 "potable," which is connected to the existing 200 mm water supply network.

The depth of the network is taken 2.20 m from the planned surface of the earth to the bottom of the pipe.

At the site of the tie-in, a 1500 mm water pit with shut-off valves according to the typical design 9010911.84 is installed.

External fire extinguishing of the reconstructed incubator is provided from two existing fire hydrants, which are installed on the designed water supply network. Fire hydrants are arranged on the site of two fire hydrants in accordance with SP 8.13130.2009.

Fire hydrants are located at a distance of not more than 2.5 m from the edge of the roadway, but not closer than 5 m from the walls of the building. Location of fire hydrants is marked in accordance with the requirements of GOST 12.4- 026-76.

Indication signs for fire hydrants are painted in identification colors in accordance with the requirements of GOST 12.402676.

Indication signs for fire hydrants are illuminated by general outdoor lighting. Signs are located on the designed supports.
