Source of sewage separation and recycling system realize that power self-support is self-sustaining, carbon neutralizes and the important leverage of resource output.Heisui River is general
From stool and urine and flushing water, the 30-40% of sanitary sewage is accounted for, COD accounts for 58%, BOD and accounts for 42%；If Heisui River receives kitchen useless
Water, then carbon source ratio will be promoted to 70% or more.
COD in Heisui River can be divided into particulate form COD, colloidal attitude COD and solubilised state COD by particle size.Certain scene is real
Discovery is surveyed, gravity drainage mode collects transport kitchen waste water and Heisui River, and total COD is 1089mg/L, solubilised state, colloidal attitude and particle
State COD is respectively 252mg/L, 202mg/L and 635mg/L.Although the COD in Heisui River is than the sanitary sewage COD high of mixed collection, directly
It connects still undesirable to Heisui River COD progress resource utilization.First is produced for example, directly being handled with mainstream anaerobic digestion process Heisui River
Alkane, anaerobic digestion unit volume is big, and heat preservation is difficult；And considerable part methane can be dissolved in water phase, not only cause resource
Loss, also to environmental emission greenhouse gases.Therefore, before using resource utilization technology, changed by biological adsorption etc.
The technologies such as enhanced coagulation are learned, the carbon source in Heisui River are captured, so that COD is concentrated and is transferred in sludge, to mention
High primary sludge yield, provides support for following resource.
The conventional articulated gravity precipitation method can only capture particulate form COD, be acted on almost without capture colloidal attitude and solubilised state COD.By
The ratio of the total COD of the sum of colloidal attitude and solubilised state COD in Heisui River Zhan is 41.8%, strengthens the capture ten of this two parts COD
Divide necessity.Currently, enhabced primary treatment technology mainly has chemically enchanced primary treatment technology, high load capacity contact stabilization process and tradition
High load capacity activated sludge process etc..Chemical primary reinforcement processing technique can strengthen the capture of colloidal attitude COD, particulate form and colloidal attitude
The capture rate of COD is close to 100%, but helpless to the capture of solubilised state COD, and capture rate is very little.
