The principle of the process flow of integrated sewage treatment equipment mainly adopts the contact oxidation method of biochemical treatment technology. The design of the combined integrated domestic sewage treatment equipment mainly calculates the water quality parameters of domestic sewage and similar industrial organic sewage treatment according to the general domestic sewage quality, and calculates the influent BOD5 at 200mg/L. Main components: 1. Hydrolysis acidification tank; 2. Contact oxidation tank; 3. Impurity sedimentation tank; 4. Disinfection treatment; 5. Aerobic sludge digestion tank.

　　1. Hydrolysis acidification tank

　　This process mainly deals with pre-treatment of sewage before treatment, which involves anaerobic fermentation of the wastewater in the water to improve its biodegradability. This is an important step before sewage treatment, which can directly affect the efficiency and treatment time of later sewage treatment, and can maximize the efficiency of sewage treatment and reduce consumption.

　　2. Contact oxidation tank

　　Oxidation tanks are classified into several levels based on the degree of pollution in water treatment, including ordinary and reinforced types. Generally judged based on the processing time. If the processing time is no more than four hours, use a regular oxidation tank, and if the processing time is between 4-6 hours, use a reinforced oxidation tank. The main method is to use the effluent from the hydrolysis acidification tank to flow automatically to the contact oxidation tank for biochemical treatment. Most of the organic matter in the original sewage is degraded and purified here. Aerobic bacteria use fillers as carriers and utilize the organic matter in the sewage as food to decompose it into inorganic salts, thereby achieving the purpose of purification. The survival of aerobic bacteria requires sufficient oxygen, that is, there is enough 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 elastic three-dimensional packing material is used in the tank. The packing material has a large surface area ratio, long service life, easy film formation, and corrosion resistance. The bottom of the tank adopts a rotary mixing aerator, which increases the transfer rate of dissolved oxygen, and has the advantages of light weight, non aging, non clogging, and long service life. The gas to water ratio of the contact pool is around 12:1. (0.5-5m3/h contact tank is secondary).

　　Price of integrated sewage treatment equipment

　　The price of integrated sewage treatment equipment is about tens of thousands of yuan, because the price of integrated sewage treatment equipment is very expensive because it can treat water quality very well and prevent water pollution in our rivers.

　　3. Impurity sedimentation tank

　　After being treated in a biological contact oxidation tank, the wastewater flows automatically into a sedimentation tank for further sedimentation and removal of detached biofilms and some organic and inorganic small particles. The sedimentation tank is based on the principle of gravity. When the wastewater containing suspended solids flows from bottom to top, the substances are precipitated by gravity. An adjustable weir is installed on the upper part of the sedimentation tank to regulate the water level of the effluent; The lower part is equipped with a conical sedimentation zone and a sludge gas device. The gas source is provided by a fan, and the sludge is transported to the sludge aerobic digestion tank by gas.

　　4. Disinfection treatment

　　According to the TJ14-74 standard, the disinfection pool should last for 30 minutes. If it is hospital sewage, the disinfection pool should increase the residence time to 1-1.5 hours. Our company uses chlorine dioxide disinfection equipment, and the disinfection pool and equipment can continuously change the dosage according to the water output, achieving the goal of adding more water and more medicine, and adding less water and less medicine. Other equipment can be separately prepared if needed.

　　The price of integrated sewage treatment equipment for industrial wastewater, disinfection tanks, and disinfection varies from tens of thousands to hundreds of thousands, with prices ranging from several million. The specific price depends on the size of your daily drainage volume, as well as your discharge standards! You can ask the sewage treatment equipment factory to calculate the price of the device based on your standards.

　　5. Aerobic sludge digestion tank

　　The remaining sludge discharged from the sedimentation tank is subjected to aerobic digestion and stabilization treatment in the tank to reduce the volume of sludge and improve its stability. The amount of sludge after aerobic digestion is relatively small. When cleaning, a suction truck can be used to extend from the inspection hole of the sludge tank to the bottom of the tank for suction and then transported outside (cleaning once every six months). A supernatant reflux device is installed on the upper part of the aerobic digestion tank for sludge, allowing the supernatant to overflow to the hydrolysis acidification tank.
