INSTALLATION FOR DEEP biological treatment of domestic and industrial wastewater

摘要

The invention relates to biological wastewater treatment with activated sludge in suspension, in particular for biological purification plants (UBS) and is intended for cleaning wastewater of residential and industrial buildings. UBO comprises a housing with an equalizing and activation chambers, a system of aeration (CA) with the means of aeration and pumping of water and sludge, connected to the compressor, connected to the control unit to supply compressed air inclusions in the aeration system of at least two sequentially alternating process cycles purification, waste water processing cycle with recycling of activated sludge and treated water output from the plant and the active water treatment cycle, according to the utility model, UBO is further provided with a camera stabilization aktivnog silt and cam post-treatment with filter and active means for cleaning the filter with the tap of contamination, as well as means for input and output of treated water, wherein CA is in the form of two aeration subsystems (AP) with the respective groups of means for pumping and aeration (HS), each of which is designed to work in only one of said waste water cleaning cycles and connected to the corresponding compressor, wherein the compressor is one of the AP is connected to the control unit, with inclusion in the work cycles only act implicit water purification, AP and the other compressor is connected to the control unit, with its switching into operation only in cycles of wastewater treatment with recirculation of the activated sludge and treated water output from the plant, wherein the installation body is formed from sheet polymeric material. In preferred embodiments, a filter is configured at least two-layer with the lower sand layer disposed on the supporting grid and upper gravel bed, with the space between the post-treatment chamber bottom and the base grid is located an active filter cleaning means arranged in a distribution pipe connected to the CA through pulsator pressure, means for removing contaminants from post-treatment chamber is in the form of airlift with switchblade line connected to an equalizing chamber, both compressor connected AP emergency distributor ensuring the possibility of switching the air supply to one or other heavy CA from one compressor, at failure of the other compressor, wherein the emergency valve is designed as a solenoid valve, as the resin material used polyethylene, or vinyls, or other such materials.
