Liquid household waste disposal, export rules, norms and pumping

Liquid household waste is water with impurities used in sewage systems. As a rule, these are drains from the kitchen, baths and toilet. In the private sector, the category of liquid waste is added by wastewater from a bath or sauna.

The danger of liquid waste

In general, liquid waste of domestic origin does not carry a serious danger. However, if they are not disposed of in time, adverse processes may begin: rotting, highlighting a pungent odor, attracting rats and flies.

The problem of disposal of liquid waste is absent in city apartments, since all the drains are sent to the sewer riser, and then go through a whole system of pipes for treatment facilities. In a private house, everything is somewhat different. Modern individual construction increasingly uses septic tanks large underground containers, where sewer drains accumulate from the house. Next, they are sucked in as an ascension machine (a car with a specialized tank and pump) and taken to a centralized collector.

Disposal of liquid waste in the city

The city sewer system is a complex engineering structure consisting of many kilometers of pipes of different diameters. The waste path starts from the sink, bath or toilet. On intraapartment communications (flexible plums, corrugations, etc.D.) They fall into the pink riser a castiron pipe of large diameter, “piercing” the apartments located above the other. In the basement, risers are introduced into the house collector, which is a pipe collecting drains and sending them outside the house.

There are many communications in any city underground, among which there are necessarily sewer collectors. These are systems of pipes of different diameters, which, cunningly connecting to each other, form a network. On this network, everything that residents merge in the sewer is going to the main collector. And already this particularly large pipe is conducting waste for treatment facilities.

City sewage systems in many ways by gravity. That is, due to a small inclination of pipes, drains on their own flow in the direction. But the slope can be provided not everywhere, so sewer pumping stations are used to promote wastewater. As a rule, these are small technical buildings where powerful pumps are installed that promote the volume of waste further, in the direction of treatment facilities.

How liquid waste disperses?

Household waste, as a rule, does not contain potent chemical components. Therefore, their disposal, or rather, processing, is engaged in treatment facilities. This term is called special enterprises, which receive wastewater from the sewer network of the city.

Classical technology for processing liquid household waste is their lease through several stages of cleaning. As a rule, it all starts with sandwriters. These units distinguish sand, land and solid particles from the eminent volume of effluents. Then the drains pass through devices separating water from any other particles and objects.

The selected water is directed for disinfection and then merges into any reservoir. Modern purification technologies allow you to achieve such a composition of output water that does not harm the environmental system of the reservoir.

A variety of huts remaining after filtering the drains is driven to silt fields. These are special sites where the remnants of the processing of drains are defended in the cells-abrupts. As it is on silt fields, moisture remains evaporated, or removed through the drainage system. Further, the dry overwhelming mass is distributed through the silt fields, mixing with the soil.
