WASTE WATER TREATMENT ECO-B

The utility model relates to the field of biological treatment, namely, devices for the purification of natural, industrial and wastewater, and to be / used to treat domestic or close to them by the content of industrial wastewater where there is no centralized sewage: individual houses, roadside motels and hotels, cafes, administrative buildings, rural schools, hospitals and social welfare institutions, industrial enterprises.

Known installation for biological wastewater treatment according to the application No. 99117237/12 of the Russian Federation, class. From 02 F 3/00, 2000, containing aeration tank in the form of a corridor closed in a horizontal ring. In this case, the aeration tank is divided by vertical partitions with the formation of sections so that in each section the water moves vertically. Each section is equipped with an aerator, and at least some sections are equipped with elements for attaching aerobic microflora. The installation also contains a sump located in the center of the indicated ring along its vertical axis. The central tube of the sump is equipped with elements for attaching aerobic microflora and is hydraulically connected to the input nerve and output second pipelines of the installation, as well as to the first section of the aeration tank. The last section of the aeration tank is hydraulically connected to the inlet third and outlet fourth pipelines of the installation. With open pipelines, the first and second, the installation works in the forward direction. With open pipelines, the third and fourth, the installation works in the opposite direction.

However, this installation has a complex and expensive design that does not allow /: to treat wastewater with a sufficient degree of purification.

The technical task of the utility model is to create a plant that is simple in design and reliable in operation with a high degree of purification.

The problem is solved in that in the proposed solution, a riser for sludge pumping is installed in the primary settler, and an aeration section and a biological treatment section are made between the primary settler and the treated water section, and the aerators are installed in the aeration section, and the biological treatment section is filled with a biological load and equipped shaking aerator

The drawing shows a General view of the installation in working position. Installation for wastewater treatment "ECO-B contains a housing 1 made of cylindrical shape and placed horizontally. In the housing 1, a primary settler 2, an aeration section 3, a biological treatment section 4 and a purified water section 5 are sequentially placed.

An inlet sewage supply pipe 6 is connected to the primary sump 2, and along the wall 7 separating the primary sump 2 and the aeration section 3, a riser 8 for pumping or 9 is installed vertically, the lower end of which is located at the bottom, and the upper end is led out through the inspection hatch 10 to surface. In addition, an overflow pipe 11 is installed in the primary sump 2 for supplying clarified water to the aeration section 3.

At the bottom of the aeration section 3, aerators 12 and airlift 13 are installed, the perforated section 14 of which is located on the bottom of the aeration section 3, and the horizontal section 15 parallel to it is brought into the primary settler 2. In addition, an overflow pipe 16 is installed in it, which goes into the biological treatment section 4. In the biological treatment section 4, at some distance from the bottom, a lattice 17 is horizontally placed, on which the biological load 18 is filled, and installed under the lattice 17. shaking aerator 19 of the biological load 18. In addition, an airlift 20 is also installed in it with access to the aeration section 3.

The purified water section 5 is interfaced with the biological treatment section 4 and is equipped with an outlet pipe 21 for purified water and an inspection hatch 22. The aeration section 3 is also equipped with an inspection hatch 23, and the biological section

Installation for wastewater treatment is as follows. ; Through the incoming pipeline 6, the effluent flows into the primary settler 2, where

settle and lighten, i.e. the sludge settles to the bottom, and water accumulates from above and is pumped through the overflow pipe 11 to the aeration section 3. Here, the wastewater is mixed and saturated with oxygen from the air and biological i is destroyed by activated sludge 9, which consists of aerobic bacteria. Active sludge 9 is generated from wastewater as a result of 15-25 day aeration. Air

;,;: 3 enters the aeration section through aerators 12 with a bubble size of 2-3 mm. Excess activated sludge 9 is pumped into the primary sump 2 by airlift 13.

After aeration section 3, treated wastewater through an overflow pipe 16

enter the biological treatment section 4 with a biological load 18, which is a plastic product. On the surface of the biological charge 18 in the course of wastewater treatment, a biologically active film consisting of bacteria grows. This film is created as a result of irrigation of the biological load 17 with water saturated with oxygen for 15-25 days. For

 periodically shaking the biological load 18 and removing unnecessary. biologically active film shaking aerator 19 operates, which include: once every 30 days for one hour.

The precipitated biologically active film is pumped by an elevator 20 to the aeration section 3, and the treated wastewater enters the purified water section 5-, from where they by gravity leave the unit through the outlet pipe 21. At a time when there is no influx of urgent water, they circulate through the unit.
