Advantages

1) Save land surface. YMHF-underground sewage treatment plant buried underground does not need to build shelter-houses and doesnt occupy land surface.

2) Distinguished effect of YMHF- AO sewage treatment plant. Effect of plug flow secondary biological contact oxidation treating is better than mixed or series complete connected treating. 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. 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) YM deodorization measures. Deodorization measures are applied for YMHF underground sewage treatment plant.

6) Auto-control. Full-automatic electric control system and damage alarm system are applied for YMHF 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. Range of application This sewage treatment equipment is wildly used in housing district, villages, towns, office buildings, stores, hotels, restaurants, nursing homes, schools, troops, hospital, super highway, railways, factory, mine, traveling scenic area. And other organic wastewater treatment and reuse in slaughter, aquatic products processing, food industry, etc.
