This device is the closest in technical essence to the claimed utility model and is taken as a prototype for the proposed utility model.

The disadvantage of this device is the lack of ease of operation of the deep biological treatment plant for domestic wastewater, due to the fact that when installing the pump it is necessary to break the power line at the intersection of the station building, the same inconvenience occurs when replacing the pump or during its preventive maintenance. In addition, during maintenance work at the station it is inconvenient to service the pump directly, since it is located in the upper part of the station building. It must be placed on a special shelf. After opening the cover of the station building, it is necessary to perform additional operations to remove it. Moreover, if the pump is not fixed, then it falls during operation, and it is very difficult to fix it not in the factory.

Disclosure of a utility model.

The present utility model, based on this original observation, mainly aims to propose a station for deep biochemical treatment of domestic wastewater, which allows at least one of the above disadvantages to be smoothed out, namely, to increase the usability of a station for deep biological treatment of household wastewater water

To achieve this goal, the station for deep biological treatment of domestic wastewater additionally includes a sealed module for the placement of electrical elements attached to the wall of the plastic housing. The housing cover has a rigid suspension for mounting the circulation pump

Due to this advantageous characteristic, it becomes possible to repeatedly disconnect the electrical connectors for all electrical equipment located at the station without violating the integrity of the electrical wires, while ensuring the integrity of the further connection and the possibility of use in the thickness of the earth and in the presence of groundwater. As well as the ability to simultaneously remove the circulation pump when opening the station cover.

There is a variant of the utility model in which the sealed module for placing electrical components is adapted to accommodate at least one outlet for connecting a circulation pump and at least one connector for connecting an external power supply.

Thanks to this advantageous characteristic, it becomes possible to connect the main electrical module of the station - the circulation pump, and to connect its plug to a standard outlet. At the same time, the integrity of the circulation pump is not violated, which is especially important while maintaining its warranty properties.

There is a variant of the utility model in which the sealed module for placing electrical components is further adapted to accommodate the on / off timer of the circulation pump.

Thanks to this advantageous characteristic, it is possible to provide the possibility of placing inside the sealed module of the device, which provides periodic on-off of the circulation pump, which increases the convenience of operation of the station - expands its operational capabilities.

An ultraviolet (UV) disinfection unit can be additionally integrated in the system. (Not shown in the figures).

It is also possible to equip the station with an SMS notification system and remote control of the treatment facilities. (Not shown in the figures).

Implementation of a utility model.

Station deep biochemical treatment of domestic wastewater works as follows:

Wastewater flows through the first, second and third chambers of the sump sequentially. The circulation pump 8 picks up the settled water from the third section 6 and sprays it repeatedly through the nozzles of the sprayer 11 above the bio-charge 14 - filter filler. The filter is the habitat of microorganisms that accelerate the decomposition of organics contained in wastewater, after which nitrates are oxidized and the precipitate is finally released and nitrogen is removed in the first chamber of station 4. The inclusion of the circulation pump 8 is on the instructions of the timer 18, which is included in the configuration of the system.

If an ultraviolet (UV) disinfection unit is integrated in the system, then the purified water after the bioreactor enters the pressure filter with a special charge and then for disinfection using a UV lamp. (Not shown in the figure). In the pressure filter of the unit, the final purification of water occurs to the values of the concentrations of suspended solids in it, corresponding to the requirements for discharge into reservoirs of fishery and household purposes. Water is supplied to the pressure filter by pumps organized in a group. A six-way valve may be located on the filter to flush the charge. The flushing time is determined by the values on the pressure gauge. The UV disinfection unit allows you to almost completely destroy pathogenic microorganisms. In bactericidal plants, sources of continuous ultraviolet radiation can be used, which act on the aqueous medium through a special material in the wavelength range of 180-300 nm.

Thus, an additional sludge disinfection system contributes to the destruction of helminth eggs and ensures the safety of direct contact with sludge during station maintenance and allows the use of sludge, for example, as fertilizer. The dosage of the ovicidal preparation for sludge disinfection can be organized automatically and is strictly synchronized with the actual productivity of the station, which allows not to reduce the level of disinfection at peak loads and saves the reagent with insufficient drainage.

To improve the usability of the deep biological treatment plant for domestic wastewater, the following operations are also carried out during the installation of the station:

- in the wall of the housing 2 cut a hole for the size of the sealed module 15 for the placement of electrical elements;

- fasten in a slotted hole, seal the gaps, for example, with a sealant;

- from the outer end of the housing 2 set the external insert 192 with the hole 28;

- in the electrical wire 20 with the plug 17 insert the sealing ring 29;

- in the electrical wire 20 with the plug 17 insert the locking sleeve 32;

- clamp the wire 20 with two inserts 30 and 31;

- both inserts are inserted into the sealing ring 29;

sealing the gaps between the electric cable 20 and the sealing ring 29 with a sealant;

- the sealing ring 29 with the inserts is inserted into the locking sleeve 192;

- the locking sleeve 32 is inserted into the external insert 192;

- insert a wire with a pressure seal 33 and with a connector for the plug 16 into the inner insert 191;

- fix the pressure seal 33 in the inner insert 191 and seal the gaps between them;

- insert the inner insert 191 into the housing of the module 26.

Without loss of generality, the installation order of the device may be different, as it allows the permutation of the steps, as well as the introduction of new steps, for example, the installation of additional sealing rings or additional sealing of the joints.

In addition, the following operations are added:

- 3 vertical rods 22 are rigidly fixed to the cover 3;

- rigidly attached to the vertical rods 22 platform 21 adapted for placement on it of a circulation pump 8;

- place the circulation pump 8 on the site 21;

- connect the vertical rods 22 to each other with a jumper 23 through connections 25. In this case, the jumper 23 is passed through the handle 24 to carry the pump 8.

- fix the circulation pump 8 to the site 21 using the jumper 23.

If you need access to the electrical connectors on the inside of the station building and disconnect the electrical connector, you must take the following steps:

- disconnect the inner insert 191 from the housing 26;

- disconnect the electrical connector.

If you need access to the electrical connectors from the outside of the station building, you must take the following steps:

- provide access to the housing 26;

- remove the sealing ring 29 with liners 30 and 31 from the retaining sleeve 32;

- disconnect the electrical connector.

If access to the circulation pump is required, the following steps must be taken:

- open the cover of 3 stations;

- remove the circulation pump 8 together with the cover 3, to which the pump is rigidly attached.

If it is necessary to dismantle the circulation pump, the following steps must be taken:

- open the cover of 3 stations;

- remove the circulation pump 8 together with the cover 3, to which the circulation pump 8 is rigidly attached;

- expand the vertical rods 22 so that the jumper 23 exits though from one connection 25 and thus releases the handle 24 of the circulation pump and the pump itself.

- remove the circulation pump 8.
