Cost has been added to include civil engineering and waterproof thermal-insulated etc., and due to the thickness of wall and thermal-insulating waterproof so that cold-storage sink
Dischargeable capacity is further reduced.
Water distributor is connected in the bottom and top of catch basin carry out water distribution, this side with one group of vibration means for main pipe for supplying water with return water supervisor
Method is the common practice of natural layered catch basin, has preferable water distribution effect for the identical catch basin of depth.But for
The different anisotropic sink of depth uses such mode water distribution, and the energy storage efficiency of cold-storage sink is usually relatively low, and due to cross section
Variation so that the flowing velocity of water in sink is difficult to hold in vertical direction, have prodigious disturbance, part in the horizontal direction
Region forms recirculating zone, and the water of this part is not only let cool without participating in storing very well, and mesolimnion can be made to expand, therefore accumulation of energy water
Slot it is less efficient.
