Common types of small sewage treatment equipment
There are many kinds of small-scale sewage treatment equipment, which can be divided into powered and unpowered sewage treatment equipment according to power. Unpowered sewage treatment equipment is mainly driven by no power or micro-power, which can achieve automation and low cost. Micro-powered sewage equipment is generally suitable for small-scale sewage treatment. For example, Kinglv environmentally-friendly rural wastewater purification system is widely used in village sewage treatment projects.

Micro-powered sewage equipment is generally suitable for small-scale sewage treatment. For example, Liding environmentally-friendly micro-powered sewage treatment equipment is widely used in village sewage treatment projects.
The power sewage treatment equipment is relatively stable, consumes less, and has less work in operation and maintenance management. It can not only realize sewage treatment quickly, but also has reliable water quality and convenient installation of equipment. However, the cost is relatively high and requires a certain amount of management personnel, which is suitable for domestic sewage treatment projects or industrial sewage treatment with large water demand.
1. Power sewage treatment equipment workflow
The process of this type of equipment is to first treat the sewage in the first-stage digester and then to the secondary digester, followed by the anaerobic filter, the contact oxidation tank, and finally the water can be discharged normally through ventilation and disinfection. When the sewage flows to the first-stage digester, it will be acid-fermented under the stimulation of the acid-producing bacteria to effectively degrade, and the alkaline decomposition can be achieved by the secondary impact of the secondary digester. In this way, the pollutants in the sewage are decomposed, and the residual organic substances can be degraded again under the action of anaerobic bacteria to enhance the dissolved oxygen content of the water body. At the same time, the disinfection method again disinfects the effluent.
2. Powered sewage treatment equipment workflow
The process of such sewage treatment equipment is firstly passed through the functions of coarse grid, grit chamber and regulating tank, then lifted by the pump, transferred to the primary filter tank, the machine room, and finally effectively disinfected in the discharge, secondary Biochemical treatment, primary biochemical treatment. The coarse grid stainless steel cage structure intercepts the floating material in the water body, precipitates the solid object, and can also perform the descaling effect in the adjustment tank. The sewage parking time is kept for half an hour to remove the organic pollutants in the water body. . The oxidation pond is a biological carrier, and the biological filter is a nude organism. Under these two cooperations, the sludge is directly oxidized. The secondary living treatment will once again work together with the primary biological treatment to improve the water quality of the sewage treatment, increase the dissolved oxygen content of the water body, and discharge it after disinfection.
