Embodiment
In preferred implementation of the present invention, as shown in Figure 1, the CRI system comprises intake pump 1, equalizing tank 2, under meter 3, diffusion cell 4 and water collecting basin 5.
At first river wastewater draws water through water pump and enters preposition high-order equalizing tank 1, because river is in flow state for a long time, make in the water settling property preferably suspended particle be in suspended state for a long time, this part suspended substance forms mud by being deposited in the equalizing tank bottom, sewage rate of percolation through this processing is improved, and prevent that the diffusion cell packing layer from stopping up, and alleviates the diffusion cell pollution load.
River wastewater enters diffusion cell 4 and carries out quick percolation treatment after the preliminary treatment of equalizing tank 1.The performance of filler and consumption are for influencing the key factor of wastewater purifying efficiency in the diffusion cell 4.For improving the hydraulic load of system, at water quality of river pollutent and the lower characteristics of organic concentration, select sand, volcanics and zeolite as filler in the diffusion cell 4 of the present invention, this filling adsorption performance is good, and a large amount of specific surface areas can be provided for the apposition growth of microorganism; Make sewage flow through microbial film with the liquid film state; Enough porositys are arranged, good permeability (promptly guaranteeing the supply of oxygen); Better chemical stability is arranged; Microbial growth is had no adverse effect; And certain mechanical strength is arranged; Raw material is extensive, and is cheap and easy to get.Usually the many more decontamination effect improvings of content of volcanics or zeolite are good more in the filler, consider the general pollution situation of river wastewater, and volcanics or zeolite content in filler is at least 15%, can suitably regulate the proportioning of each component in the filler according to the requirement that purifies water.
The thickness of thickness of filter bed is another factor that influences decontamination effect improving.Generally speaking, thickness of filter bed is big more, and the water environment capacity of system is strong more, and hydraulic detention time is also long more, and the effluent quality of system will be good more; Yet thickness of filter bed is big more, and the investment cost in the engineering reality is also high more.Investigator of the present invention has studied pollutent decontamination effect improving in system and with the rule of change in depth thickness of filter bed has been defined as 1-4m, is preferably about 2m.
Routine CRI system generally adopts the operation scheme of alternation of wetting and drying in operational process, promptly have the phase of flooding and fall two stages of dry spell.The phase of flooding refers to sewage and oozes pool surface from beginning to batch to, stops the residual water in rear surface up to batching and falls dried for some time; Fall to referring to dry spell after sewage stops to batch, ooze the residual water of pool surface and fall to doing the back to for some time of water distribution next time.
In CRI system operational process, a waterflooding and the dried circulation that constitutes that once falls are called hydraulic load cycle (the Hydraulic Loading Cycle of system, HLC), waterflooding time (waterflooding phase) and the ratio that falls to doing the time (falling dry spell) are called wet-dry ratio in the one-period.The design of HLC directly affects the difficulty of treatment effect and operational administrative.The adjustment of HLC in process of the test comprises the adjustment of HLC size and the adjustment of wet-dry ratio.Investigator of the present invention has carried out lot of experiments for different HLC and wet-dry ratio to all contaminations removal effect, finally determines the processing parameter of CRI system in operational process.Studies show that, adopt CRI of the present invention system, wet-dry ratio is about under 1: 1 the operation scheme, and the clearance of each contamination index is best relatively.
Average amount of infiltrating water in the one-period, promptly the sewage quantity of handling on the unit time land area of one unit is called hydraulic load (Hydraulic Loading Rate).Hydraulic load is big more, and pollution load is also big more, and the time that pollutent stops in system is short more, and filtrate is not thorough to organic absorption yet, thereby influences treatment effect.Therefore, hydraulic load should be controlled in the limit, in order to avoid cause sluicing strong excessively, causes biomembranous loss, reduces biodegradable effect on the contrary.Corresponding hydraulic load calculation formula is as follows:
Under the constant situation of system's floor space, CRI system hydraulic load is by the filler infiltration rate, also has the hydraulic load cycle to determine jointly.The filtration media penetrating quality of system is good more, and then the water yield of handling in the unit time is also big more.The influence of hydraulic load cycle to hydraulic load mainly shows as the influence of wet-dry ratio adjustment to hydraulic load, and when system's infiltration rate changes when not obvious in time, then bigger wet-dry ratio can improve the hydraulic load of system.The hydraulic load of CRI system of the present invention and technology can reach 6m 3/ m 2D.
Below in conjunction with the drawings and specific embodiments the present invention is further elaborated.
