What should be done with the waste collected by the municipal sewage treatment plant?

Waste is collected at a specific collection point, and toxic and hazardous waste is put in special containers for landfill. Some waste is industrially filtered, omitting the residue and repeatedly filtered until it meets the emission standards.

There are many methods of sludge treatment and disposal at home and abroad, generally using concentration, digestion, dewatering, drying, effective utilization (mostly for agriculture), landfill and incineration, etc., or using several methods to combine disposal.

Of course, it can be transported to the garbage dump for disposal, after all, these garbage are general household garbage, and there is no harmful effect.

Hello, the waste liquid from the sewage treatment plant belongs to the industrial waste <>

According to the different ** and nature of wastewater, it can be divided into different types such as domestic sewage, industrial wastewater, and agricultural wastewater. In the process of sewage treatment, some sludge and waste liquid will be generated, which mainly include sedimentation tank sludge, biological tank sludge, filtrate, etc. These waste liquids contain a large amount of organic matter, nitrogen, phosphorus and other pollutants, and if they are not directly discharged into the environment after treatment, they will cause serious pollution to water bodies and soils.

Therefore, the waste liquid of the sewage treatment plant needs to be specially treated to remove the pollutants in it and can only be discharged after it meets the discharge standard. <>

The sewage treatment plant itself treats sewage and wastewater, where does the wastewater come from? Or what kind of wastewater do you mean?

In fact, many people have this problem, every day every building will produce a lot of wastewater, erection and feces, and finally go to **? I haven't seen a place to dispose of feces in the community, so today I'll explain to you what the feces in our city have gone.

The first level,Production of feces

There is nothing to say about this, it must be public toilets, household horses, buckets and other places.

The second level,Septic tanks

The first step of the wastewater and feces produced is here, and there is a slight difference here: the old community is generally a septic tank (Figure 1), and the new community is a biochemical tank (Figure 2).

<> whether it is a biochemical tank or a septic tank, the purpose is actually the same, to separate the feces and divide them into a silt layer and a clear water layer.

The third level. Municipal wastewater treatment plants

The wastewater from the clear water layer generated by the second pass is directly treated by the city's sewer to the city's wastewater treatment plant, and after treatment, it is generally discharged to wetlands and other places to return to nature.

The fourth level,Fertilizer processing plant

In the second pass, not only waste water but also sludge residue is generated, which needs to be sucked out by a suction truck and transported to the fertilizer processing plant, where the manure and other residues will be turned into agricultural fertilizer, and the wild slim boy will eventually return to nature.

At this point, all the feces and urine we produce have been processed, eating and drinking Lazar This is a must for people's lives, although the processing of feces feels disgusting, and it is indeed stinky, but someone has to do it, otherwise our city will not be able to live at allPlease do not need to discriminate against the staff concerned

Solid waste, sewage, air pollutants, etc., which need to be treated and disposed of for different types, and the following are the common treatment methods: travel marketing.

1.Solid waste treatment: Solid waste usually needs to be sorted, incinerated, and buried in a variety of ways.

Classification refers to the collection, classification, compression and other treatment of reusable waste, incineration refers to the treatment, reduction or conversion of waste into treatable or reusable substances through thermal energy, and landfill refers to landfill treatment of waste that cannot be incinerated or classified, which is the most commonly used disposal method in industrial countries.

2.Sewage treatment: Municipal sewage needs to be sludge treatment or sewage treatment.

Sludge treatment refers to the capture and treatment of suspended solids, organic substances and microorganisms contained in sewage; Sewage treatment refers to the gradual purification of wastewater through physical, chemical or biological methods to meet the standard of discharge level.

3.Air pollutant treatment: Air pollutant treatment mainly includes reducing emissions, controlling soot and dust, controlling industrial waste gases, and promoting clean energy to solve air pollution problems.

The above are some of the more common treatment methods for sewage in the city, of course, there are some other treatment methods, such as resource utilization, biotechnology treatment, etc., which need to be selected according to the type of sewage and the development of the corresponding treatment technology.
