Fish Pond Wastewater HDPE Filter Media

Fish Pond Wastewater Filter Media / White 100% Virgin HDPE Filter Media

Product Description

MBBR is a new type of biofilm reactor, which is developed on the basis of fixed bed reactor, fluidized bed reactor and biofilter. It overcomes the shortcomings of the complex operation of the fixed bed reactor which needs regular backwashing, the fluidized bed reactor which needs to fluidize the carrier, the submerged biofilter which needs to clean the filter material and replace the aerator. It also retains the characteristics of the traditional biofilm method, such as anti impact load, less sludge output and long sludge age. Compared with the activated sludge process, it can keep more nitrifying bacteria and has better denitrification effect because of the long sludge age. Its main principle is to use the sewage to flow through the reactor packing carrier continuously, and then form the biofilm on the carrier. When the microorganism propagates and grows on the biofilm, it can degrade the organic pollutants in the sewage, so as to purify the sewage

Discriminant index

1. Adhesion of biofilm

Adhesion capacity of biofilm - the most important index to evaluate the quality of fillers: biological adhesion = protected surface area (connected with the design of fillers

running state

Structure related) × bioadhesion per unit surface area (related to the performance of filler)

2. Filler performance

Performance of packing - the most important index to evaluate the biological adhesion of packing

(1) Surface properties of fillers

1. Surface structure: it is generally considered that the surface roughness is large and the film hanging speed is fast.

2. Surface potential: generally, microorganisms are negatively charged, and the surface of filler is positively charged, which is suitable for microbial growth. 3. Hydrophilicity: the microorganism is hydrophilic particle, and the filler has good hydrophilicity and is suitable for microorganism growth.

Film hanging state

(2) Hydraulic properties

1. Porosity: volume occupied by filler, high porosity.

2. Shape and size: affect the flow pattern of water and air flow.

(3) Fluidization performance: it is related to the density of filler. The density of the packing should be 0.97-1.03, and fluidization can be achieved with less aeration or agitation.

Technology Parameter

Application

1. The fluidized bed biofilm reactor can be used to remove organic matters and nitrogen. The flow bed biofilm reactor process can be used to remove conventional pollutants, even nitrogen and other nutrients in wastewater. The process has the advantages of simple equipment, flexible operation, saving land occupation, convenient operation, and can be used independently, in series or in parallel. It can be used for the purposes of nitrogen and phosphorus removal, high concentration wastewater removal and sewage treatment The new construction, reconstruction and expansion of the plant can increase the load, improve the treatment effect, reduce the floor area, etc;

2. Combined with the characteristics of biofilm process and activated sludge process in the same treatment unit, the activated sludge process with flotation packing can improve the capacity of BOD / COD removal and the function of phosphorus and nitrogen removal of the existing activated sludge process. This method is suitable for the transformation of the traditional activated sludge method. Without new structures, the function and efficiency of the system can be improved;

3. Applied to filtration of fish pond or high-purity Aquarium

Application advantages

1. Fast start-up, short transformation and commissioning period;

2. Large biomass, strong resistance to impact load;

3. Save energy, land and investment;

4. It can be applied flexibly in aerobic, anoxic and anaerobic sections;

5. It is directly added without new structures:

6. It is especially suitable for the upgrading of wastewater treatment plant and the deep denitrification treatment;

7. The technology is also used in the construction of integrated equipment, which can effectively save 1 / 3-1 / 2 of the floor area compared with the conventional process, and the management is also simpler.
