(54) METHOD FOR DISINFORING WATER

g631456

a biological pond, and the first one is the culture of algae, which ensures the e-continuity of the process of mass development of wild species of algae,

. With the mass development of algae in the biological pond, the amount of nutrients in water sharply decreases and the algae cells, due to the lack of nutrients, again pass to the rest stage, while others, not having time to settle in the first JQ pond, go to the second pond and , settling to the bottom or lysirus, stimulate the development of not flagellated forms of algae, but from the order of the esoccaE .es, 15

The water in the second pond is more than one day ;; as in the first, and two, and here in the mass algae of the genera diEoveeea, Scenedesmus.Ah-kistfcdesmuSjLageftieimia and others develop. In this period, the density of algae in plankton is 30–40 ppm, cells / ml, the water is supersaturated with dissolved Oxygen and in vivo algae, which cause the belle of all pathogenic bacteria. 5 If algae from PäeEatci and BaYeBa r-ioptivtci develop in the first pond, which feed on ready allochtonous organic matter, then in the second pond algae of species 30 PfOiococca e5, KOTOpb M develop, mineralized food is necessary for survival. The mass development of algae from the Protococcal ones releases water from mineral substances and 35 B11K, 5 pond waters during this period is 3-5 mg O / l, which is typical of natural water bodies. This water, entering the third biological pond, and, after 40 days, passes through 40 days, is released from algae by invertebrate organisms intensively vegetating in it.

At the exit from the third pond, the density of algae in the water is 5 not more than 1 mln.kl / mp, and the MIC rises to 6-7 mg O / l due to organic excreta of the invertebrates, although the oxygen content in this water is still high. The JQ output from the third biological pond, when algae are introduced into biological ponds, is 1-0.1, and the causative agent of the Siberian ulcer is not sown not only from 0.1, but also from 1 to 5 ml of purified water. The above indicators confirm the fact that water that is decontaminated in the same way can be considered epidemiologically safe when entering natural water bodies. °

Example 2. Disinfecting wastewater in biological ponds that are unsuccessful for Siberian drivers at a temperature below + 10 ° C.65

The method of implementation is the same as in the first example, only here a culture of green algae A „FdEcatus is grown, which is introduced into the first biological pond at the rate of 1.5-2 liters of culture of algae per 1 m of wastewater.

The introduction of such a culture of algae into the pond causes mass development of wild-growing cold-loving algae species from Pliacus diEofogoniumjNitzsctMa, No (vicuCa, Trac1iiEomonas, Lepocincece, etc.) The water is saturated with dissolved oxygen to 10-12 mg O / L and transferred to the second pond. 1) Fo eetatci species settle in the first pond or go to the second pond, where they no longer have enough nutrients, settle to the bottom or lyse, thereby stimulating the mass development of wild species of algae from diEot-offoniow.Cti & oreCa in plankton and BaciEEoMoptistaB bent pond Algae, which are adapted to the growing season at 4-6 s from CtiEorog-onium, Lag-erhehifa.ScenedestTios, a also HaNitzschia.NanicuEa.CsmbeEta.PinuEaria, and others, also developed to a density of 30-35 ppm. / ml in plankton and up to 4-5 mln.kl. 1 cm in the benthos saturate the water with oxygen and in vivo secretions and provide water disinfection in the second

-WILLING

When disinfecting water at a temperature below, the depth of the third pond should be at least 120140 cm, which ensures complete deposition of algae in the pond or at the outlet in front of the natural pond, micro filters are installed on which the algae are captured. All indicators obtained in the second example are similar to the results at low temperatures and water enters epidemiologically safe natural reservoirs, and supersaturation of purified water with dissolved oxygen to some extent contributes to the healing of natural waters.

From the examples it is clear that the introduction of algal cultures causes the directional development of wild-growing species of algae, which are adapted to specific conditions of habitat in ponds.

Having developed in bulk, they in the process of photosynthetic aeration supersaturate the water with dissolved oxygen, as well as physiological secretions that have a detrimental effect on the pathogenic microflora and, in particular, on the Siberian ulcer.
