Abstract

Device is intended for wastewater treatment. The invention aims to increase the efficiency of water-treatment equipment. In the proposed device at least part of a settling tank is made of expanded-clay and/or of no-fines* concrete.

Description

The invention relates to liquids in suspension ^; materials, petroleum products, and can be / used for surface wastewater treatment. i _; 5 There are known anti-fitration equipment _: · Constructions; : consisting of a sand blast, a polyethylene film and a sand blast.

These structures fitting protective layer of sand is only a constructive element and not used for additional cleaning of wastewater (Priešfiltracinių devices from polyethylene plėvelėsdirbtiniams: _water bodies in the design and construction instruction SN551 - 82, M., 1983, p. 6).

The closest to a technical solution is a stormwater storage and purification unit consisting of / '-' '.' '/ A multi-section planter that is supported. consists of a polyethylene film, a protective filtration layer and a ..circular circuit, as well as feed and drain piping (USSR / Application No. 5002570/26, CO2F1 / 00,

1991).

The disadvantage of the known device is the inadequate utilization of the individual elements into the elements, since special elements are required for the introduction of partially purified water, into the protective sand layer, and the concrete circuit as: the filtration element is not used. It is an object of the present invention to make more efficient use of elements of a device. and the simplification of the complex of purification plants. This is achieved by the fact that at least part of the concrete cone is made of expanded clay concrete and / or beige concrete. .

The newly stated technical solution has - another arrangement of elements and new connections between them, and a purpose

thanks to these new ones.

of the signs referred to

The drawing shows the proposed device: Fig.1 - plan, 'V .. λ. , FIG. 2 - A fall according to A-A in FIG. ; The unit consists of sections of a multi-section planter 1, a concrete outline 2 (Fig. 2) equipped with back filters. and laid drainage pipelines 3, which are connected to a common collecting pipeline which has spouts 4 in all sections. At least part of the concrete outline 2 is made of expanded clay or concrete, or it can be used together.

, In the proposed technical solution, the reinforced aerated concrete is laid in strips in the less recessed part of the planter.

The total area of the concrete outline lined with expanded clay concrete is calculated as the passage of the water to be treated (this is equal to the passage through the filtering material).

Below the concreted circuit 2 there is an anti-friction device consisting of a protective filter layer 6, a polyethylene film 7 and a preparatory layer. Calculate the thickness of the sand for the passage of water to be cleaned to protect the water from the protective layer

The section has sloping entrances for 8 excavation technicians to enter, using it to remove drained sediment from the planter sections

Each section of the planter also has water drainage piping 9, pre-treatment filters, oil collection and discharge facilities (Figure -'-

· ^{; 3} not shown). In the deeper part of the planter are provided back-filters 10, where laid drain pipes 11 are used for drainage of purified water.

• ·

The device is working. yes. The rainwater drainage pipeline 9 enters the planter section 1 where it settles. The wastewater passes through the pre-treatment filter and the expanded concrete or loam concrete strips 5 to a protective filtration layer 6, where the purified water is supplied through the back filter 10 and the drainage pipe 11 is supplied to the consumers. The protective filtration layer 6 can, if necessary, be cleaned by introducing a biological preparation '* Degradoil. ·

After the water has settled in the appropriate section of the planter, the partially decontaminated water is removed as described above and the precipitate is dried by switching on. to the drainage piping 3, which feeds to a neighboring filled section for cleaning.

Drain sediment is removed from the section by means of an excavation through the entrance 8.

In the proposed installation, partially purified water is further treated in the protective filtration layer of the installation by introducing it through a non-piping network. o directly through a concrete circuit, at least part of which is made of expanded clay or concrete. As a result, the construction of feed pipelines becomes redundant, and the concrete outline of the accumulating tank sections is actively exploited.
