The plant with advanced biological treating method assembling our own research and practice is a whole set of buried sewage treatment plant. The plant is a kind of expected plant with obvious treating effect, taking the place of normal septic tank.
The virtues for the plant are obvious. First, the effective plant with stable technical performance, low cost, convenient maintenance operation, can remove BOD5, COD, NH3-N. Extra shelter-house and heating insulation are not needed for the plant. Second, the plant, over which flowers and grass can grow, doesn't occupy land surface and that is the reason why it has no influence on the surroundings.
For the treated sewage by the plant, the water quality can highly meet discharge standards. If necessary, water reuse equipment can be designed according to clients' actual needs.
1, Hotels, restaurants, sanitariums, hospitals.
2, Home communities, villages and towns
3, Stations, airports, harbors,
4, Factories, mines, troops, scenic spots,
5, Industrial organic sewage, such as municipal sewage
1. Save land surface. WSZ-underground sewage treatment plant buried underground does not need to build shelter-houses and doesn't occupy land surface.
2. Distinguished effect of WSZ- AO sewage treatment plant.
1)Effect of plug flow secondary biological contact oxidation treating is better than mixed or series complete connected treating.
2)Plug flow secondary biological contact oxidation pond is smaller than activated sludge pond and do not have expansion of sludge, acquiring strong applicability of water, strong impact strength, stable treated water quality.
3)Newly dimensional elastic material taken into use, with larger area, easier biofilm formation better enhance oxygen solubility in the water.
3. Less after-treat sludge. Less quantity of sludge after treatment which only needs to be discharged once 1 or 2 years.
4. Less noise. Not only silencing measure for noise reduction of normal blower, but also newly materials for Sound-absorbing is applied. The noise of operation is controlled below 50 decibel which reduces the influence to environment.
5. Better deodorization measures. Deodorization measures are applied for WSZ underground sewage treatment plant.
6. Auto-control. Full-automatic electric control system and damage alarm system are applied for WSZ underground sewage treatment plant. Normally, there is no need for a person to manage the plant; It only needs maintenance every month or every quarter.
4. Recommended reason
1. Capable of treating organic sewage
2. Anti-corrosion carbon steel, stainless steel ensures long life time;
3. The whole set can be placed underground with auto-control and easy operation.
