2. utilize the physiographic relief drop not have the drop oxygenation of energy consumption
Utilize city, mountain region physiographic relief drop to carry out drop oxygenation, realized the no energy consumption of oxygenation process.The characteristics that this channel is big according to the hilly small towns terrain slope; The staged channel is set, makes sewage in flow process, pass through the topographical elevation difference drop oxygenation on the one hand, further the aperture is set simultaneously through partition wall at channel; Impel sewage in the drop process, to form injection; Carry oxygen and get into the floating stuffing reaction zone, further strengthen oxygenation, whole oxygenation process need not power consumption.
3. drop water aeration formula sewage transport is handled channel purification efficiency height
Drop water aeration formula WWT channel system purifies sewage through comprehensive actions such as physical adsorption, biological degradation and filtrations, and highly-efficient treatment is stable.Partition wall is set in channel on the one hand stores sewage, and filler formation saprobiont reaction zone is set, guaranteed that sewage and floating stuffing have the sufficient contact reacts time; Simultaneously carry a large amount of mikrobes in the effluent sewerage and have higher activity, and be bonded on the floating stuffing, for the continual and steady efficient purification of biosystem provides assurance.On the other hand, the biological purification system that in long and narrow channel, makes up, similar multi-stage biological membrane reactor; Through purifying along journey; Form good microbial species heap sort at the raceway groove different section and distributed, in floating stuffing, formed the synchronous nitration and denitrification microenvironment, strengthened denitrification efficiency; And channel endways section the rich calcium filler of granular rich iron is set, strengthened the dephosphorization and the filtering efficiency of system.
4. technology is simple, investment is low, need not special-purpose occupation of land, simple and convenient management
Drop water aeration formula WWT channel utilizes the water drain space, and the collection sewage transport of structure is an one with purifying, and in the remote conveying function process of channel, has realized the purification of sewage, and technology is simple, investment is low; Utilize the physiographic relief drop not have the energy consumption drop oxygenation, processing cost is low; Particularly this treatment facility need not the special-purpose occupation of land of Sewage Plant, and maintenance management is easy, in the WWT of villages and small towns, mountain region, has a good application prospect.
It is thus clear that; This drop water aeration formula sewage transport is handled channel collection sewage transport and is purified to one, utilizes the water drain space, utilizes the physiographic relief drop to carry out drop oxygenation; In long distances channel; Partition wall is set and filler is set, in carrying channel, be built into the reinforced sewage treatment system, have treatment efficiency height, reduced investment, no energy consumption, need not characteristics such as the special-purpose occupation of land of Sewage Plant.
