The role of johkasou in rural sewage treatment

The johkasou is a small domestic sewage treatment equipment used for the treatment of dispersed domestic sewage or similar domestic sewage, and different tanks have different roles, for example: the sedimentation separation tank is used for pre-treatment to remove particles of larger specific gravity and suspended solids, and to improve the biochemistry of the sewage; the pre-filtration tank is equipped with fillers, and under the action of the anaerobic biofilm on the fillers, the soluble organics are removed; the aeration tank is set with aeration, high filtration speed, The aeration tank integrates aeration, high filtration speed, retention of suspended solids and regular backwashing; the overflow weir of the sedimentation tank is equipped with a disinfection device to disinfect the effluent.

The function of the purification tank is to purify the domestic sewage, which is a kind of sewage treatment facility using physical and biological technology to effectively purify the domestic sewage, with strong sewage treatment effect. The johkasou mainly treats all domestic sewage such as kitchen, bathing, laundry and similar sewage including faecal sewage. The structure of johkasou is different, the function is also different, generally speaking, johkasou includes pretreatment, biochemical treatment, sedimentation, filtration and disinfection steps, after the johkasou treated water can be connected to the pipeline network or directly discharged to the creek or farmland.

What are the functions of johkasou and septic tank? Firstly, johkasou is a device for collecting and purifying sewage, used for collecting domestic sewage from toilet, kitchen, shower, etc. Septic tank only has the function of collecting sewage from toilet. Secondly, the johkasou mainly relies on physical and biological technology to effectively purify sewage, using aeration equipment to increase the amount of dissolved oxygen, accelerate the formation of biofilm, thereby enhancing the effect of sewage purification, septic tank is the use of sedimentation and anaerobic fermentation to deal with faecal wastewater.

In addition, the rural domestic sewage treated by the purification tank can reach the Class B standard in the Pollutant Discharge Standard for Urban Sewage Treatment Plants (GB18918-2002), and some purification tanks can even reach the Class A standard, and the quality of septic tank effluent is generally in the Class B standard in the Pollutant Discharge Standard for Urban Sewage Treatment Plants (GB18918-2002). -2002) in the class B standard or below. Most importantly, the price is different, the price of the purification tank should be at least 3,000 yuan, or even a few thousand yuan, and the price of the septic tank is generally ranging from 500-2,000 yuan.

So according to the different needs of the scene and the economic ability to pay, in the choice of equipment, you can choose according to their own reagent needs.
