Inquisitive minds often ask the
Inquisitive minds often ask the questions that not every layman would think. For example, where sewage is flowing? And this is really extremely interesting.
Rumors about this go variety. Someone said that all the city's sewage flows directly into the river, so to bathe on city beaches is not recommended.
Others claim that liquid waste goes into the ground for special wastes, and there are absorbed into the bowels of the soil.
However, if you imagine how many millions of cubic meters emit every day, residents of Moscow, so no soil is not enough to "suck" in itself.
First of all, I must say that for companies there is a different, individual cleaning system. That is, with a city-wide sewage waste from large plants are not related.
Typically, such a system has a cycle: the water used for technical purposes, then she goes for treatment and then returns to the shop for the next use.
It's all clear. And what about the city sewer? As an example, take Moscow.
Often nowadays you can hear the indignation over the fact that soon the Moscow river is becoming a swamp due to the fact that it almost directly drain millions of tons of sewage waste from cities and even companies.
In fact, all is not so simple. If this were true, then the Moscow river long ago would be a real sump, and all who bathed there, were infected by different STDs.
Immediately it should be emphasized that household waste of human life in liquid form are flocking to special treatment facilities that are available in each city. This is a key point.
When the liquid waste from city sewers flow into sewage treatment plants, they undergo an initial purification step, which resulted in the precipitate falls Il.
You will be surprised, but it is a really interesting fact: from this sludge then make... gas.
Schematically, the process of purification of sewage as follows:
So, in the beginning there is a flow of sewage to the treatment system through a giant pipe. Traffic is equal to approximately 2, 5 million cubic meters per day:
Next, the first treatment stage filtration special grates waste that are larger than 10 mm:
Now the water enters the sump, where it is located exactly two hours. During this time, the settled organic matter is sent to biogas production, and the rest – on the system:
This is the second sump:
In General, there is a constant analysis of water coming from the drains of the town, and purified water:
And only after such a thorough cleansing water flows into the Moscow river directly from this tank:
Now you know where flows all the sewage of Moscow and what happens with sewage and other impurities. Approximately by the same principle of cleaning work to all cities of the world.
Otherwise, the very existence of cities would be impossible.
