Today, according to experts, there are a great variety of diverse, and most importantly, effective methods of water purification, including biological, chemical, and mechanical.
In this article, we will consider in more detail such an issue as biological wastewater treatment. Today it is the most popular and at the same time effective.
Biological wastewater treatment is practiced exclusively in one type of existing treatment plant - the so-called autonomous sewers. Of course, this method is innovative, based on the use of special bacteria, which, in turn, decompose organic compounds into carbon and water.
It is important to note that the microorganisms used in this method are conditionally divided into two small groups: aerobic and anaerobic. Their main difference is that the first type requires oxygen-rich water. In the second case, the presence of O2 is not necessary at all.
How is biological wastewater treatment carried out?
Firstly, after the waste enters a special station, it settles for some time, resulting in the process of fermentation and clarification.
At the next stage, already clarified waters enter another chamber, where the process of active fine bubble aeration takes place.
At the last stage, the final cleaning takes place due to the presence of sludge, which is already saturated in an oxygen environment.
It is important to recall that biological wastewater treatment mainly implies the almost complete absence of extraneous unpleasant odors. According to experts, this method has a large number of positive aspects, among which it is necessary to note the possibility of reusing the liquid. But in this case, already pre-purified water can be used exclusively for economic purposes, for example, for watering plants.
On the other hand, chemical wastewater treatment is no less popular. This method is usually carried out through the use of three methods: neutralization, oxidation and reduction. Of course, such a solution is very effective, however, due to the high cost of electrochemical oxidation, it is used quite rarely.
In conclusion, it should be noted that today such an issue as water disposal and wastewater treatment is considered very relevant. Otherwise, if everyone pollutes nature, in the near future humanity will face a terrible ecological crisis.catastrophe. Moreover, when using, for example, the biological method, everyone has the opportunity, as noted above, to reuse the resulting liquid for economic purposes, which indicates the saving of natural resources. Already today, experts are sounding the alarm and calling for the use of the biological method, which is the most reasonable and at the same time effective solution.

2017 has been declared the year of environmental protection in Russia, and therefore environmental education is one of the tasks for this year. Wastewater generated during the economic activities of enterprises contains a large amount of pollutants in concentrations exceeding the permissible and normative ones. As a rule, we are talking about heavy metals (iron, nickel, copper, lead, mercury, cadmium, etc.), oil products, suspended solids, aluminum, and surfactants. These substances, getting into water bodies, violate the norms
