Abstract

A three-chamber biological waste water treatment plant comprises: (a) an inlet chamber which incorporates a basket (1) which prevents the onward movement of faeces; (b) oxygen is introduced to the inlet chamber through a submerged tube (10); (c) the second chamber has a lid which incorporates a propeller (8) and drive shaft (7) linked to an external motor, an air compressor (9) and inlet (10) to the first chamber; (d) the second chamber incorporates a chalk dosing assembly (12); (e) the assembly is operated by a monitoring and control system (11) which also documents the processes including temperature, pH values and chalk doses (12); and (f) the assembly has a final biological filter (13).

Description

According to the invention in the generic term, biological-mech anical activation kit for domestic wastewater treatment, cleaned and clarified.

To improve wastewater disposal and the associated relieving the waters to make our earth viable received, it is inevitable an optimal, natural, not bring incriminating solution.

The biological measure of the treatment lies according to the invention in the field of psychrophile and mesophile microorganisms, through the mechanical treatment.

This system requires a 3-chamber device (3 stages), Fig. 1, Fig. 2, Fig. 3. Wherein in the pre-settling tank Fig. 1 there is a retention basket 1 or a retention grille, faeces - floating parts - are more difficult to remove Parts are held back to rot. By supplying air oxygen 10 there is already a split, dissolution and decomposition. The bacteria do the preparatory work so that the sludge, after taking the pH value into account, can be removed with the basket, dried and returned to the soil.

According to the invention, the core of the system lies in the Belebungskam mer Fig. 2. Here the rules of natural science are observed. In order to ensure thorough mixing of the activation chamber, while at the same time supplying sufficient atmospheric oxygen, to promote bacterial cultures and microorganisms, there is a geared motor 4 on the clarification chamber cover 3 , for driving and mechanical circulation by means of a propeller 8 . By a compressor or high-performance cooling fan 9, air is the oxygen in the line 10 to the chambers FIG. 1 and FIG. 2 performed to.

The operation is carried out in time intervals according to the Chamber loading, leaving a latent period for development phase of the bacterial strain is given.

Due to the mechanical circulation and the simultaneous air supply leadership, a humane, gentle methodology is achieved which Revitalization guaranteed. Ammonia and toxins become neutral  lized.

A metering device 12 can be used both in the activation chamber in FIG. 2 and in the secondary clarification chamber in FIG. 3. Lime can be added in doses according to the required pH value.

According to the invention, the biological mechanical retrofitting can can also be installed in liquid manure pits (liquid manure). With the help of mechanical circulation, no fixed Place components on the chamber floor.

To comply with the rules, a monitoring station is set up 11 (control cabinet). A time counter (operating hours), an electricity meter, a timer, and a fault detector are arranged especially for precise control and monitoring by the authorities.

On the other hand, in the monitoring station (switch cabinet) 11, the control for the dosing system 12 , the sensor 14 determines the temperature and the pH value. In the sewage sludge retention basket ( FIG. 1) 1 , the sewage sludge ( FIG. 1) 15 is displayed in the monitoring system 11 after a maximum height has been reached.

According to the invention, if an optimal clarification is not achieved, a filter bag 13 is inserted in the secondary clarification chamber FIG. 3. In this filter bag 13 , a filter system can be brought, such as. B. sand.

If larger post-cleaning is required, an additional Sand filter shaft can be connected downstream.  

TITLE - TOP CONCEPT

Fully biological wastewater treatment for individual properties with mechanical stirring device and atmospheric oxygen supply.

USE

According to the generic term, the system is considered to be retroactive Aeration kit for existing 3 chamber sewage treatment plants used, but also in connection with new plants and this system can be used for agricultural slurry plants be used.

TASK

The invention has for its object organic house water to clean logically, with the revitalization of microorganisms and bacterial cultures.

SOLUTION TO THE TASK

The system is based on the generic term for small sewage treatment plants (Sedimentation pits - septic tanks - 3-chamber pits). In the antechamber (sedimentation pit) the fixed and floating components. In the 2nd chamber (aeration chamber) takes place by means of a mechanical agitator in the Ship's screw system intensive mixing - um Rolling with simultaneous supply of atmospheric oxygen to revitalize the microorganisms and bacterial cultures.

STATE OF THE ART

Small sewage treatment plants without mechanical agitation and movement direction with high air supply.

DISADVANTAGES OF THE PRIOR ART

Due to the high air supply to the activation chamber, a large ventilation device given that the turned brought air must escape again and thereby also unreleased worked odors (e.g. ammonia) in the environment be transported.
