1. The ability to resist impact load is strong, and the average residence time of contact oxidation method is over 6 hours.
2. It has the ability of denitrification and phosphorus removal and can be used to deal with industrial wastewater, domestic sewage and
urban sewage by adjusting the structure of the equipment. ;
3, most of the fillers in the contact oxidation tank are composed of soft packing, light weight, high strength, stable physical and chemical
properties, large specific surface area, strong biofilm adhesion ability, high contact efficiency between sewage and biofilm.
4, the aerator is used for aeration in the contact oxidation tank, so that the fiber bundle is constantly floating, aeration is uniform, and the
growth of microorganism is mature, which has the characteristics of activated sludge process.
5. The water quality of the effluent is stable, and the production of sludge is less and easy to be treated.
6. The submersible pump can be installed in the equipment to reduce the investment of the project.
7. The equipment can be located on the ground or buried in the ground. When buried in the ground, the upper cover can be used for greening,
less area and less ground structures in the factory.
8. It is easy to complete automatic control and simple management operation.
9. The equipment can be connected to a car to make a mobile integrated sewage treatment equipment.
Main ingredients: 1. Hydrolysis acidification pool. The contact oxidation pond. The impurity of the sedimentation tank 4. Sterilization treatment. Aerobic sludge digestion tank.
1. Hydrolysis acidification pool
In front of the sewage treatment process, the main front of water treatment, it is possible to increase the fermentation wastewater by anaerobic biological wastewater, this is an important step in front of the sewage treatment, and the latter can be directly in the treatment of the wastewater treatment by a part of the time effect on the efficiency and reduce the efficiency and improvement in the maximum degree of consumption of sewage treatment.
2. Contact oxidation tank
Some of the oxidation pool is divided into grades, and according to the degree of the common type of water pollution. In general, it is judged that the time of treatment. The processing time and enhances the oxidation pool is usually used for the treatment of 4 - 6 hours of oxidation pool use no more than four hours. The main purpose of the biochemical treatment of wastewater using catalytic oxidation pond to hydrolysis acidification pool. Most of the organic materials and original wastewater degradation in the purification of the organic matter in sewage with aerobic bacteria for food to a career in the decomposition of organic matter in the waste water, inorganic salt, so as to achieve the purpose of purification. Enough for the survival of aerobic bacteria have oxygen to the aerobic bacteria, dissolved oxygen, to achieve the purpose of biochemical treatment of sewage. The aerobic pool, provided by a blower, a new elastic filling tank, the area ratio of the filler surface, long service life, easy film formation and corrosion resistance, the rotation of the mixing aerator at the bottom of the pool, dissolved oxygen, high speed, light aging by, not easy to be blocked and has a long service life. The water in the pool to contact air ratio is about 12: 1. Back to H level of contact pool.
3. Impurity sedimentation tank
Sewage by biological contact oxidation pond, the flow of water in the settling tank, precipitation, and several of the biofilm removal of organic and inorganic particles, a settling tank, based on the principle of gravity from the wastewater containing suspended solids on the bottom upward flow by gravity materials to calm down. The water weir is provided for adjusting the upper water outlet of the sedimentation tank, and is provided with a sludge gas precipitation area and the lower cone. Provided by the gas source of the fan, and the air stripping by sludge, aerobic sludge digestion tank.
4. Sterilization treatment
The disinfection pool intimate association TJ 74 relation standard for 30 minutes. In the case of hospital sewage disinfection of water in pool, to increase the residence time of 5 hours. The company, which 二酸化塩素殺菌裝置 can change the amount of pond water treatment disinfection sterilizing device by the amount, the more water, in order to realize more medical treatment, less and less water, we need it it is necessary to separately provide with another device. (for example, a disinfection pool. The industrial waste water, and disinfection device.
5. Aerobic sludge digestion
From the settling tank is discharged to reduce the amount of sludge, sludge, in order to improve the stability of sludge treatment in the pool in the treatment of stable and aerobic digestion. Washing sludge aerobic digestion, and less on the suction tank bottom sludge after the suction tankerage Sinotrans available from sludge tank inspection hole (cleaning once a year). In the hydrolytic degradation of supernatant liquid reflux device is set in the acidification pool of aerobic sludge digestion supernatant to the overflow tank top.
