Aquaculture sewage system solutions
Small sewage treatment equipment
Device Name:
Small sewage anaerobic treatment equipment
Effluent standard:
The effluent water quality reached the water quality index of dry farming in the "Farmland Irrigation Water Quality Standard (GB 5084-2021)", and the project carried out resource utilization of sewage.
Scope of application:
Small and medium-sized farms, small-scale sewage treatment projects, rural toilet reform projects, etc.
Equipment advantages:
The treatment effect is good. The sludge in the reaction area is fluidized under the action of biogas and backflow water, which strengthens the surface contact of mud and water.
With baffles, it can maintain the sludge concentration in the reaction zone, prevent sludge loss and maintain the reaction efficiency.
The equipment load is high, and the sludge thus maintains a high activity and can bear a high sludge load.
The equipment has a high effluent standard, and the effluent water quality meets the water quality index of dry farming in the "Farmland Irrigation Water Quality Standard (GB5084-2021)".
Biogas project
The process of wet anaerobic fermentation-CSTR was adopted
Products:
The biogas is generated for heating, and the biogas slurry is returned to the field
Advantages:
√ Mature and reliable technology
√ Strong resistance to system impact
√ Simple operation
√ Low energy consumption during fermentation
√ High volume gas yield
Project Case:
Sewage treatment works
Single system/dual system/triple system solution
Single system composition:
USR/UASB/CSTR;
Purpose:
Generate biogas fertilizer and biogas; Biogas is used for heating, and biogas slurry is returned to the field.
· Centralized treatment of fecal water
· Reduce investment in waste disposal facilities on farms.
Dual system composition:
USR/UASB+ two-level AO;
Purpose:
Generate biogas slurry fertilizer + farmland irrigation water;
Biogas slurry is first used for land consumption;
Not enough land:
Farmland irrigation water can be directly generated for farmland irrigation.
Three systems:
USR/UASB+ tertiary AO+MBR+ Fenton/ozone;
Purpose:
Biogas slurry fertilizer generation + farmland irrigation water + Grade A river discharge water;
The surrounding land is not enough, and it can be directly discharged into the river through the first-level A discharge treatment.
Product advantages:
√ Mature and reliable technology
√ Wide range of applications
√ Easy maintenance and stable operation
√ High degree of harmlessness
√ Professional after-sales service team
√ Low degradation rate of nitrogen and phosphorus
√ High volume load ratio
√ Save investment and floor space
√ According to the actual situation of the user, different solutions can be selected
Project case
New Hope - Shandong Laixi Hagezhuang aquaculture sewage treatment project
Annual capacity: 250,000 tons
Treatment material: pig manure water
End product standard: field irrigation standard
Processing standard: GB5084-2001
New Hope - Shandong Laixi Songwangzhuang aquaculture sewage treatment project
Annual capacity: 120,000 tons
Treatment material: pig manure water
End product standard: field irrigation standard
Processing standard: GB5084-2001
Tianbang - Anhui Chizhou aquaculture sewage treatment project
Annual capacity: 54,000 tons
Treatment material: pig manure water
End product standard: Class A emission standard
Processing standard: GB8978-1996
The project builds A regional treatment center, equipped with three system treatment equipment (liquid fertilizer + farmland irrigation water + aquaculture level 1 A discharge standard).
It can flexibly deploy the emission standard configuration, which can not only meet the first-level A emission standard, but also meet the farmland irrigation standard, but also generate biogas slurry fertilizer; It can be selected according to local environmental requirements, thus reducing operating costs and investment costs.
