1、 Process Description
1. Hydrolysis acidification tank
The purpose of hydrolysis acidification process is to provide pre-treatment for subsequent aerobic biochemical treatment. The retention of wastewater in the hydrolysis tank has an anaerobic fermentation effect, further improving and enhancing the biodegradability of the wastewater, which can increase the subsequent biochemical reaction rate, shorten the biochemical reaction time, reduce energy consumption, and reduce operating costs.
2. Contact oxidation tank
The water from the hydrolysis acidification tank flows to the oxidation tank for biochemical treatment. The oxidation tank is divided into two levels, where most of the organic matter in the original wastewater is degraded and purified. Aerobic bacteria use fillers as carriers and organic matter in the wastewater as food to decompose the organic matter into inorganic substances, thus achieving the purpose of purification. The survival of aerobic bacteria requires sufficient oxygen, that is, sufficient dissolved oxygen in sewage, to achieve the purpose of biochemical treatment. The air in the aerobic tank is provided by a fan, and a new type of combined biological filler is used inside the tank. The filler has a large surface area ratio, long service life, easy film formation, and corrosion resistance. The bottom of the tank is equipped with a rotary mixing aerator, which increases the transfer rate of dissolved oxygen. At the same time, it has advantages such as light weight, non aging, non clogging, and long service life.
3. Sedimentation tank
After being treated in a biological contact oxidation tank, the effluent flows into a sedimentation tank to further precipitate and remove the detached biofilm and some organic and inorganic small particles. The sedimentation tank is based on the principle of gravity, and when wastewater containing suspended solids flows from bottom to top, gravity acts as a force to precipitate the substances. The effluent after sedimentation in the sedimentation tank is clearer and more transparent. The lower part is equipped with a conical sedimentation zone and a sludge lifting device, and the settled sludge is lifted by air lift to the sludge aerobic digestion tank.
4. Sludge aerobic digestion tank
The remaining sludge discharged from the sedimentation tank is subjected to aerobic digestion and stabilization treatment in the sludge aerobic digestion tank to reduce the volume of sludge and improve its stability. The amount of sludge after aerobic digestion is relatively small. During cleaning, a suction truck can be used to extend from the inspection hole of the sludge tank to the bottom of the sludge tank for suction and transportation (cleaning once every six months).
5. Disinfection pool and disinfection device
At present, there are many disinfection methods, such as liquid chlorine method, ozone method, sodium hypochlorite method, chlorine dioxide method, etc. Although the sodium hypochlorite method has the advantages of convenient dosing, low price, and high reliability, it can combine with certain organic compounds in water to generate carcinogenic organic halides. Chlorine dioxide is an internationally recognized broad-spectrum and safe disinfectant. Its safety is listed as the fourth generation AI grade disinfection product by the World Health Organization (WHO), and its disinfection ability is 2.6 times that of sodium hypochlorite, far higher than other chlorine series disinfection products. (Disinfection device will be provided separately according to user needs)
