Description

The utility model relates to the field of sewage treatment plants, and more precisely to sanitary installations intended for biological wastewater treatment. The utility model can be used to treat sewage in houses that do not have a centralized sewage system.

Known local installation of biological wastewater treatment, containing a housing with a heat-insulating jacket, ventilation pipe and inlet and outlet pipes. The casing is a sectional container divided by a heat-conducting wall and a water trap into a drip biofilter and a digester with membranes in the middle part (see PM RU 43891 U1 according to class E03F 5/14 for 2004).

The disadvantage of this installation is the low degree of wastewater treatment.

The problem to which the proposed utility model is directed is to increase the degree of treatment of domestic wastewater.

The technical result from the use of the proposed utility model is to reduce the concentration of pollutants in wastewater.

The above technical result is achieved due to the fact that the biological wastewater treatment plant, comprising a housing with a heat-insulating jacket, a ventilation pipe and inlet and outlet pipes, which is a sectional tank divided by a heat-conducting wall and a water seal into a drip biofilter and a digester with membranes in the middle part , according to the proposal, is equipped with a bubbling device and precipitating brushes located on both sides of the membrane located closer to the heat conduit the wall, and the inlet pipe at the end is ⊥-shaped, and the drip biofilter is a three-layer loading of expanded clay, shungizite and geotissue, while the water seal is made elongated with an outlet located above the center of the surface of the drip biofilter, and the bubbling device of the drip biofilter is made of perforated tubes.

The applicants did not find information sources containing the same general set of features specified in the utility model formula, which allows us to conclude that the proposed technical solution

the criterion of "novelty."

A utility model is shown in the figure, which shows a longitudinal section of a local biological wastewater treatment plant.

The local biological wastewater treatment plant comprises a housing 1 with a heat-insulating jacket 2, a ventilation pipe 3 and a supply pipe 4 and a discharge pipe 5. The housing 1 is a sectional container divided by a heat-conducting wall 6 and a water trap 7 into a drip biofilter 8 and a digester 9 with membranes 10, 11, covered with a sealed cover 12, in which three hatches 13 are made.

The membranes 10 and 11 have openings 14 in the central part, and the membrane 11, located closer to the heat-conducting wall 6, is provided with settling brushes 15 on both sides.

The supply pipe 4 at the end is made ным shaped for uniform distribution of incoming wastewater.

The drip biofilter 8 is a three-layer loading of expanded clay, shungizite and geotissue, in the lower part of which there is a bubbling device 16 made of perforated tubes 17.

The nozzle of the hydraulic lock 7 is made elongated with an outlet 18 located above the center of the surface of the drip biofilter 8.

The installation works as follows.

Waste water from the plumbing fixtures of a country house flows by gravity through pipes through the inlet pipe 4 to the digester 9. Incoming effluents are evenly distributed throughout the first section of the digester 9 due to the ⊥ shape of the end of the nozzle 4. All solid sediment fractions that enter the digester 9 with water are accumulated at the bottom in the form of sediment.

In the first section of the digester 9, the incoming wastewater is clarified and the gradually accumulating sludge is processed by fermentation. The second and third sections of the digester 9 serve to separate the clarified water from the non-clarified water, which passes through the holes 14, while the brushes 15 serve to additionally capture contaminants. From the third section of the digester 9, the clarified water through the outlet 18 of the water trap 7 enters the drip biofilter 8. Pouring into the center of the drip biofilter 8 from the elongated nozzle of the water trap 7, the effluents of the clarified water are evenly distributed over the surface, thereby increasing the working area of the biofilter 8. In the biofilter 8 drains are finally cleaned, passing through layers of expanded clay, schungizite and geo-fabric, which is facilitated by a bubbling device 16 made of perforated tubes 17. The draft created by the ventilation ruboy 3, enables air passing through outlet pipe 5 and the perforated tube 17, sparging apparatus 16, to penetrate all layers of the boot, which speeds up occurring in the biofilter 8 biological and biochemical processes.

From the bottom of the biofilter 8, the treated effluent flows through a discharge

branch pipe 5 into the water intake well (not shown in the figure).

To create the most favorable conditions for the treatment processes, the body 1 of the biological wastewater treatment plant is made monolithic, which excludes the possibility of untreated wastewater entering the soil. The outer surface of the housing 1 is covered with a heat-insulating jacket 2, providing a constant temperature inside the installation, which is necessary for the cleaning process. The heat-conducting wall 6 between the drip biofilter 8 and the digester 9 serves the same purpose.

The upper part of the digester 9 and biofilter 8 is hermetically closed by a reinforced concrete cover 12, in which three reinforced concrete hatches 13 are provided for cleaning sections of the digester 9 and replacing the loading of the drip biofilter 8.

Using the proposed utility model will improve the quality of wastewater treatment.
