Coarse pretreatment building

The coarse preliminary cleaning building is a new two-storey pavilion-type building with plan dimensions of 37,6x16,2m. The building is being erected on the site of the dismantled facilities of the existing treatment facilities (mechanical cleaning systems). The height of the building is about 12 m, with a flat roof on two high-rise levels with attics. The walls of the first floor are reinforced concrete walls with a gabion structure, an earthen embankment is adjacent to the rear transverse wall, connecting the level of the "Primary Settling Tanks" with the second floor of the "Rough Pre-Cleansing". On the ground floor, at el. + 3,630 there is a place for placing two containers, a pit for acidic hydrolysis of primary sludge, an electrical panel room with a separate entrance and a space for shut-off and control valves at the distribution facility at the end of the building are also designed. On the second above-ground floor, there are in series: a platform for a deodorization unit, under which there is a reinforced concrete inlet channel. In this channel, wastewater flows from the pressure chamber (located at the outer wall of the building) to two reinforced concrete gutters with multi-grid cassettes (grids) , further to two sand traps located symmetrically, and further from them to the distribution facility. From the distributor, wastewater flows through the pipeline through the basement reinforcement room from the facility to up to four primary clarifiers. On the second aboveground floor, in addition to the technological water treatment line, there is a bathroom, space for two sand washers and utility rooms. The outer walls of the 2nd floor will be self-supporting from TrimoRaster system sandwich panels, 120 mm thick with non-combustible mineral wool insulation, with factory enamel painting RAL 9006, which are attached to a reinforced concrete frame of columns and rails). The basement of the building is made of monolithic reinforced concrete, with a GK gabion structure, 500 mm thick. up to the level of the second floor, the foundation is a monolithic reinforced concrete slab. Window structures - PVC profile with insulating double-glazed window, painted in dark gray, RAL 7026. Gates - sectional aluminum, with plastic trim, painted in dark gray, RAL 7026. Visible parts of the front surfaces of concrete structures will be made of high quality concrete. The appearance of these concrete surfaces must meet aesthetic requirements. Why should boards made of laminated plywood be used in the construction of the formwork. To ensure the necessary working conditions for workers, a bathroom is provided on the second floor of the building. Natural lighting of the building is adopted according to SNiP 23-05-75 * "Natural and artificial lighting". The use of fluorescent wall lamps and windows in the outer walls of the facility is envisaged. The use of window blocks is envisaged, allowing them to be opened for airing the facility and cleaning windows. The noise and vibration levels of the process equipment do not exceed the maximum allowable values ​​established by the current sanitary rules and other regulatory documents of the Russian Federation.
