In recent years, with the rapid development of tourism and real estate, more and more  advanced hotels and villas which are often far from the municipal wastewater treatment plants.That bring inconvenience to the centralized treatment of domestic sewage. A new sewage treatment equipment, "integrated sewage treatment equipment", has successfully solved the above problems.

The practical application shows that the "integrated sewage treatment equipment" is an ideal and convenient management equipment. It is widely used in the treatment of domestic sewage, replacing the septic tank with low removal rate and that the effluent can not reach the national comprehensive emission standard. "Integrated sewage treatment equipment" is widely used. It has the following advantages:

①It can save space

"Integrated sewage treatment equipment" can be buried below the surface, the surface can be used as a greening or square land, so the equipment does not occupy the surface area, does not need to cover the room, and does not need heating and thermal insulation.

②Longer than 15 years of service life

The "integrated sewage treatment equipment" is made up of pools, and the steel structure is shallow. The steel structure pool interpenetrating network anticorrosive coating is used for anticorrosion. It is a kind of rubber network and plastic network through the formation of interpenetrating network polymer, it can withstand acid, alkali, salt, gasoline, kerosene, aging resistance, abrasion resistance, can prevent rust. After the equipment is generally painted, the anticorrosion life can reach more than 15 years.

③The effect of decontamination is good and the water quality is stable

The AO biological treatment process in the "integrated sewage treatment equipment" adopts a push flow biological contact oxidation tank, and its treatment effect is better than the complete mixed type or two or three stage series fully mixed biological contact oxidation pool. Moreover, it is smaller than the activated sludge tank, and has good adaptability to water quality, good impact resistance, stable effluent quality and no sludge bulking. At the same time, a new type of elastic solid packing is used in the biological contact oxidation tank. It has a large actual surface area, and it is convenient for microorganism to hang film and remove film. Under the same organic load conditions, the removal rate of organic matter is higher than that of other fillers, and the solubility of oxygen in the water can be improved.

④Lower Sludge production, sludge is discharged once in 90 days

As a result of the use of biological contact oxidation tank in the AO biological treatment process, the volume load of the filler is low and the microorganism is in the phase of its own oxidation, so the amount of mud production is less. In addition, the moisture content of sludge produced by biological contact oxidation tank is much lower than that of activated sludge tank. Therefore, the "integrated sewage treatment equipment" produces less sludge and generally takes only about 90 days to discharge sludge.

⑤Good deodorization effect of soil facility

"Integrated sewage treatment equipment" is equipped with soil deodorizing facilities. The utility model utilizes the upper space of the reinforced concrete structure pool to set up the improved soil and the air pipe. When the malodorous ingredients are dissolved in the water contained in the soil through the soil layer, and then due to the surface adsorption and chemical reaction of the soil into the soil, it is finally decomposed by the microorganisms in the soil to achieve the deodorization purpose.

⑥Do not need a special person to monitor

"Integrated sewage treatment equipment" have automatic electrical control system and equipment damage alarm system, equipment reliability is good, so usually do not need special management at ordinary times, only a monthly or quarterly maintenance and maintenance.

⑦Low noise

"Integrated sewage treatment equipment", in addition to the conventional blower silencing measures (such as vibration isolation pad, muffler, etc.), also set a new type of sound absorbing material on the inner wall of the blast machine room, making the noise less than 50 decibels running, reducing the impact on the surrounding environment.
