Hospital Wastewater Treatment Plant,Buried Domestic Wastewater
Treatment Equipment
Product Description
High quality underground human domestic package wastewater
treatment is an underground plant which adopts the advanced
Biological technology and the company’s scientific research and
engineering practice result, it can efficiently remove nitrogen and
phosphorus .
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
construction, neither heating and heat preservation.The surface can
be used as green land or square land.It also can be placed on
ground based on client's requirement.
As the most efficient sewage treatment device, it is widely used in
treating the sewage in the area of senior hotels, village districts
and residential districts, etc. The water after treatment would
meet the national emission standards. The water after be treated
can be used to irrigation.
Process Characteristics
1. MSC-MBBR is to make up for MBBR's poor dephosphorization effect.
Kaiyuan Group combined MBBR with the denitrification and
dephosphorization effect process and improved the combined process.
Suspended fillers are added to the aerobic tank to increase biomass
and biological species, thereby improving treatment efficiency.
2. Since the density of the filler is close to that of water, it is in
a state of complete mixing with water during aeration, and the
environment for microbial growth is gas, liquid, and solid. The
collision and shearing effect of the carrier in the water makes the
air bubbles smaller and increases the oxygen utilization rate. In
addition, each carrier has different biological species inside and
outside, with some anaerobes or facultative bacteria growing
inside, and aerobic bacteria outside, so each carrier is a
micro-reactor, so that nitrification and denitrification reactions
exist simultaneously , Thereby improving the treatment effect.
Suitable for comparison of domestic sewage treatment processes in
hospitals, hotels, hotels and scenic spots
| Process type | advantages | disadvantages | investment |
| The activated sludge method | Has strong adaptability to different types of sewage | Poor operation stability, prone to sludge expansion and sludge loss | Low investment |
| Biological contact oxidation method | has high impact load resistance and stable operation; high volume
load and small floor space; low sludge output; no need for sludge
return, simple operation and management | Partial shedding of the biofilm caused a slightly higher
concentration of suspended solids in the effluent | Investment in the middle |
| Membrane bioreactor | has strong resistance to impact load, high quality and stable
effluent water quality, effective removal of SS and pathogens;
small footprint; low or no residual sludge output | The gas-water ratio is high, the membrane needs to be backwashed,
and the energy consumption and operating costs are high | High investment |
| Biological aerated filter | The effluent quality is good; the operation reliability is high,
and the impact load capacity is strong; there is no sludge
expansion problem; the volume load is high and the secondary
settling tank and sludge return are omitted, and the area is small.
Backwashing is required, and the operation mode is more complicated |
Backwashing is required, and the operation mode is more
complicated; the amount of backwashing water is large | Higher investment |
| MSC-MBBR | has high processing efficiency, strong denitrification ability,
strong impact resistance, simple operation control, simple
maintenance, small footprint, short construction period, and low
energy consumption | Even aeration is required to prevent local packing from
accumulating, and grid plates are required to prevent the packing
from losing with the treated water. The input cost is slightly
higher than that of the activated sludge method | Low investment |
Product Advantages
The MSC-MBBR process has comprehensive advantages in the following
aspects:
1. Intelligent and precise aeration, air lift sludge return
control;
2. Application of sludge gas stripping backflow technology, more
energy-saving;
3. The noise in the boundary area is less than 40dB, and there is
no peculiar smell;
4. Energy consumption 0.3-0.5kWh/m3 sewage;
5. Occupying 0.4-0.8m2/m3 sewage;
6. The equipment runs automatically without special personnel on
duty;
7. It can implement remote monitoring and control, and realize
cluster networking and remote central monitoring; 8. The equipment
can be integrated and modularized, which greatly shortens the
construction week. Factory standardized prefabrication, quality is
more guaranteed;
9. Suspended packing and double-layer ball packing have large
biomass, easy to hang film, no balling, no blockage.
10. The main material of the equipment box adopts special steel
plate for container, which has good anti-corrosion effect of
weather-resistant steel, second only to stainless steel in
anti-corrosion, and comparable to stainless steel after
anti-corrosion, and has a long service life;
Application scope
Hotel,restaurant,community etc domestic sewage treatment recycle
Industrial and mining enterprises,remote village,sentry ,tourist
area etc domestic sewage recycle.
Each kind of industrial sewage (similar to domestic sewage) :such
as hospital sewage,pharmaceutical sewage ,washing sewage,food
sewage etc
Our Projects
Dengfeng City, Henan Province (Buried)
1. The villages and towns in Dengfeng City did not have newly built
sewage treatment facilities, but the new rural sewage treatment
terminal equipment was built due to the urging of the Zhengzhou
Municipal Government;
2. The implementation villages are located in mountainous areas,
some villages are scattered, and the sewage treatment scale is
small (5 tons, 10 tons, 20 tons);
3. All use underground installation form;
4. Use carbon steel anti-corrosion structure;
5. There are no flush toilets in the local area, and the sewage
concentration is high;
6. The process is required to have the characteristics of high
efficiency and stability, high processing efficiency, and strong
impact load resistance;
7. Facilitate unified management and establish a long-term
operation and management mechanism.
