1. Overview
The device is an underground plant (also can be above the ground)
which adopts the advanced Biotreatment technology and the company’s
scientific research and engineering practice result, it can
effectively remove BOD5,COD and NH3-N. The device is characterized
by the stable performance, effective treatment, economical
investment, automatic operation, convenience of maintenance and
small occupying space. There is no need for plant construction,
neither heating and heat preservation. The surface can be used as
green land or square land.
As the most efficient sewage treatment device, it is widely used in
treating the sewage in the area of senior hotels, villa districts
and residential districts, etc. The water after treatment would
meet the national emission standards.
2. Main Features
(1) The device can be buried below the earth’s surface. The surface
can be used as green land or square land. Therefore, the device
covers no surface area. And there is no need for plant
construction, neither heating and heat preservation.
(2) The device use plug flow biological contact oxidation pond, the
effect is better. Besides, it is smaller than active sludge pool.
The applicability to the water is stronger, impact resistance
performance is good, discharging water is stable, there is no
sludge expansion. In addition, the new elastomeric stereoscopic
materials in the oxidation pond have a higher removing rate, and
also can improve the water solubility of oxygen.
(3) Because of the low volume load of fillings in AO bio-treatment
technology of the device, and microbes are in the stage of oxygen,
it would produce less mud. Generally only 90 days for one sludge
removal.
(4) Except for the conventional air exhaust, the device is equipped
with soil deodorization measure as well.
(5) The device is equipped with fully automatic electric control
system and equipment damage alarm system. The device has a good
reliability, generally, there is no need for special management, a
monthly or quarterly maintenance is ok.
3. Usage
(1) The device can be used in treating the domestic sewage and
related organic sewage;
(2) The device features easy operation, automatic control, it can
be buried under the ground;
(3) Convenient maintenance, the working life can be more than 30
years.
4. Application
(1) Hotel, brewery, restaurant, sanatorium, hospital, school;
(2) Residence community, villa district, village, town;
(3) Station, airport, seaport and dock;
(4) Factory, mine, army, beauty spot;
(5) All kinds of industrial sewage similar to the living sewage,
etc.
