What does sewer mean, and what does it mean to go up and down?

A: Sewer girls are a group that is even poorer than slum girls.

What do you mean by sewer girl?

Sewer girl, as an Internet term, is usually used by girls to laugh at and ridicule their limited financial ability. For girls, in addition to the daily expenses of food, clothing, housing and transportation, more chopping operations are used in skin care products and cosmetics, which are essential necessities of life, so the daily expenses are very large, so the term "sewer girl" is used by girls to complain that they can't afford to consume too much, and it is an exaggerated statement to complain about their poverty.

Upper water: The tap water that you usually drink is the upper water.

Sewerage: Domestic sewage and industrial wastewater are collectively referred to as sewerage.

For example, it is used as cooling water in thermal power plants, car washing, toilet flushing, watering lawns, etc. There are many interpretations of the definition of reclaimed water, which is called "reclaimed water" in sewage engineering, and "recycled water" or "reclaimed water" in factories, which is generally marked by water quality requirements.

Water supply technologyThe water supply system draws its water from a variety of locations, which are properly treated, including groundwater, surface water (lakes and rivers), and desalinated seawater. Water treatment steps typically include purification, chlorination, and sometimes the addition of fluorinating agents.

The treated water is collected into the reservoir by gravity or pumped by water and passes through water towers or through surface facilities**.

Once water is used, wastewater is generally discharged into the sewer system and treated in sewage treatment plants before being discharged into rivers, lakes, oceans, or reused for landscaping, irrigation, or industrial use.

Launching into the water has multiple meanings. It generally has the following six meanings:

1. Drain water. 2. Put it in or slide into the water.

For example: the launch of a ship.

3. It is a metaphor for joining the gang to do bad things.

For example: she pulls him into the water with a hue.

4. Edible livestock offal.

For example: pigs in the water, sheep in the water.

Drainage generally refers to the internal organs of animals, or generally refers to other animal organs other than muscles. Due to the different customs and eating habits of different places, the specific scope of the water is also very different. And there are huge differences in the status of water in different food cultures:

In some cultures, all organs other than animal meat are among the wastes that should be discarded; In other cultures, water may be a more valuable food than meat. Sometimes the water is also called offal, but offal can also have different meanings.

5. Geographical noun refers to rain, snow, hail, etc.

6. Cantonese literal translation of "falling into the water".

The sewer leads to the sewage treatment plant. It is purified and discharged into the river and sea by the sewage treatment plant. Sewers are a type of urban public facility that has been used as early as the ancient Roman period.

The prototype of the modern Shinto Ferry and Sailing originated in France, which still has the largest urban sewer system in the world.

Sewerage: Generally speaking, the sewer system is used to collect and discharge domestic wastewater generated in the city and industrial wastewater generated in industrial production. The most magnificent sewers of the ancient world left by the Idalarians to the Romans later

Maxim sewers. Around the 6th century B.C.E., The Idalarians dug the sewers that drained into the Tiber River, the main channel of which was more than 16 feet wide, and was later expanded by the Romans. The 7 branches of the sewer flow through the city streets and eventually flow into the main road, the Maxim sewer.

Get into the waterDrain dredging refers to the blockage of sewers in everyday life, including toiletsFloor drains, sewer pipes for sinks, vegetable sinks, etc. Some of these pipes are clogged due to accidental drops or installation errors.

Some pipelines will be scaled during use, which will make the inner diameter of the pipeline thinner and affect the normal sewer discharge. In the above two cases, it is generally easy to deal with the use of pipeline dredging machine to dredge directly or the use of pipeline dredging particles, which is really not possible to replace the pipeline.

If cement is entered during the renovation process, it is very difficult to dredge, and there are very few people who can effectively deal with it, so the cost is also very high. In practice, the largest workload is municipal pipeline dredging.

The sewer is clogged with a quick unclogging method:

1. After the sewer is blocked, we can use water pressure dredging and other methods to quickly dredge the sewer, if the objects in the sewer are relatively small, then you can use a wide tape to seal all the sewers, to ensure that there is no gap at the edge. After sealing, the sewer can be unclogged after a while, at this time we can open the faucet and flush the sewer a lot.

2. You can also use acid and alkali things for dredging, if you feel that it is too disgusting to use a leather puff, then we can also use baking soda.

Mix some vinegar, mix it in a ratio of 1:2, stir it well and then slowly add some water, pour it into the sewer, wait for a while, we pour it down a few more times, and the sewer can be dredged by us after repeating for more than ten minutes.

3. If there is hair or objects in the sewer, we can use the wire to dredge, the wire dredge slowly stretches into the sewer, and constantly rotates to lift up, at this time the hair and other solids in the sewer pipe will be pulled up by us, and the sewer will be dredged by us.

4. Caustic soda can also be used.

Pour it into the sewer and it can also be quickly unblocked.

5. It is recommended that the sewer must be dredged in time after the sewer is blocked, because if the grease, hair and vegetable residue in the sewer are not dredged in time, the sewer will be deodorized for a long time, affecting some fresh air indoors, and there will be parasites.

It's also a disservice to yourself.

General flow direction: sewage flows into septic through indoor drainage pipes, and then discharges to municipal sewage pipes, collects through the combustion leakage of municipal pipelines, and flows to urban sewage treatment plants. After treatment, it is discharged into rivers or used for irrigation of farmland.

1. If there is a reclaimed water reuse system in the community, it means that the sewage is collected into the community water treatment structure through the pipeline, and then used for greening water or toilet flushing after advanced treatment.

2. If there is no sewage treatment plant in the city, it will be discharged directly into the river.

According to the statistics of the 2015 Annual Report on Environmental Statistics, the national wastewater discharge in 2015 was 100 million tons, an increase over 2014. 100 million tons of industrial wastewater discharge, less than in 2014; accounted for the total amount of wastewater discharge, a decrease of one percentage point compared with 2014.

100 million tons of urban domestic sewage discharge, an increase over 2014; accounted for the total amount of wastewater discharge, an increase of one percentage point over 2014. Centralized pollution control facilities discharge 100 million tons of wastewater (excluding urban sewage treatment plants, the same below).

The sewer is generally in two places, one is near the bathroom, this sewer is mainly used for the discharge of domestic water in the bathroom, and the other is near the kitchen, which is used for the discharge of domestic water from kitchen waste.
