The process of sewage treatment and the equipment used

See how sewage turns decay into magic?

Nowadays, it is generally a small sewage treatment plant project. Generally, it includes regulating tanks, hydrolysis acidification tanks, anaerobic tanks, aerobic tanks, secondary sedimentation tanks, sand filter tanks, and chlorine dioxide disinfection equipment. The regulating tank is a pool, calculated according to the stay, with a few walls in the middle, hydrolysis acidification and anaerobic pools are mainly sealed, and there are hanging fillers, like feather dusters, or stirred.

The difference between the two pools is the time when the water is off. The aerobic pond has surface impeller aeration and blast aeration, etc., which must be stirred. A secondary sedimentation pond is a pool.

Sand filter tank chlorine dioxide disinfection equipment, you check it. These are the basics that you need to apply for or something.

Different sewage treatment processes will also be different, such as yours in the construction of the treatment plant, first of all, to know what kind of sewage is being treated, and then to see what kind of process and equipment is better.

Depending on the water quality, the process flow is mainly three-stage, pretreatment, biochemical treatment, and advanced treatment, and the equipment is matched accordingly.

I can only work with you on the sludge dewatering machine, and I don't know much about the rest.

It's available in environmental engineering textbooks and water pollution control engineering textbooks.

Integration of sewage treatment

Advanced oxidation technology

The index of the treated water is not the same, the process equipment is different, such as the treatment of soft water (higher than the tap water standard) requires RO equipment, medium speed filter, multi-media filter and other main equipment, the equipment listed by the upper brother is commonly used auxiliary equipment, not core equipment.

Too many things for people to write for you? It's not realistic, unless people who are full and have nothing to do, labor must be paid.

First of all, it is necessary to know the water quality and quantity of sewage, and it is best to have a water quality test report. According to the plan and the specific situation of the site, the construction drawings will be made, which will also involve a lot of equipment.

Different processes are selected according to the requirements of different water quality and treated water quality.

Different sewage processes are different, see what type of sewage it is.

Grid, Conditioning Tank, Hydrolysis Acidification Tank, Contact Oxidation Tank, Sedimentation Tank, Intermediate Pool, Quartz Sand Filter, Activated Carbon Adsorber, Disinfection Tank.

**It has a lot to do with the equipment you choose, non-standard equipment** and the quality is very different, the investment should be about 600,000 (this is difficult to say), and the choice of process has a greater impact on investment

What sewage? Different water quality has different treatment processes and construction costs.

For example, 20 tons of TNT wastewater will have an investment of more than 500,000 yuan. The operating cost is also about 100 yuan tons.

The investment of the easiest 20 tons of domestic sewage is more than 100,000. The operating cost is more than 1 block per ton.

It depends on how the sewage enters and what the effluent labels are.

I don't seem to see you talking about sewage!

There are many types of pollutants in sewage, according to the concentration of different pollutants equipped with a relative treatment process to meet the requirements, simply summarized chemical method (that is, adding chemicals to produce chemical reaction to form a precipitate, after precipitation removal), biochemical method (through chemical reaction + biological reaction to remove pollutants in the water), physical method (usually using filtration, the general chemical treatment time will be equipped with the same physical principle to implement). The specific process also needs to be determined according to the characteristics of the wastewater.
