Background technology
Ice cream waste water mainly refers to the waste water of workshop discharge in the production process of ice cream.At present, raw materials for production mainly milk, cream or animal-plant oil and other auxiliary condiment etc. of ice cream, the mainly organism such as milk-protein, dairy fats of the pollutent therefore in ice cream waste water, also has a large amount of greases simultaneously.After the organic waste water of this high density height grease enters water body, if exceed the environmental capacity of water body, then can consume the dissolved oxygen in water body in a large number, cause water body to occur anoxic even anaerobic.Under the condition of water hypoxia, due to the effect of anaerobion, organism is degraded to harmful frowziness gas such as CH4, CO2, NH3 and a small amount of H2S, water quality deterioration is turned black smelly, causes the death of fish, finally cause water pollution, environmental disruption.The method processing ice cream waste water is in the market all directly by the aerobic treatment process of blast aeration.This technique can reach 90% even higher to the clearance of COD, stable, but because in ice cream waste water, organic content is higher, need to consume more oxygen amount to decompose, thus consume too many dynamic power, working cost is higher, and aerobic process produces a large amount of excess sludges simultaneously, and the disposal costs of mud is also a no small expense.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides the system of the process ice cream waste water that a kind of technique is simple, running cost is low.For achieving the above object, the utility model provides following technical scheme:
The treatment system of a kind of ice cream waste water of the present utility model, comprise the grid, pump well, air flotation pool, acidifying equalizing tank, anaerobic pond, Aerobic Pond and the second pond that are connected successively by water pipe, between described pump well and air flotation pool, between described acidifying equalizing tank and anaerobic pond, be provided with lift pump; Described air flotation pool is connected with air dissolving system, and described acidifying equalizing tank and Aerobic Pond are connected with gas blower; Described acidifying equalizing tank, anaerobic pond are connected with sludge sump by mud pipeline with second pond; Described sludge sump is connected with sludge filter press.
Improve as one of the present utility model, between described second pond and Aerobic Pond, be connected with sludge reflux pipeline;
As a kind of preferred version of the present utility model, the integrated skeleton construction of described acidifying equalizing tank, elastic filler is loaded in body bottom, pond, and the height of described elastic filler is 1.4-1.6 rice, and body top, pond is equalizing tank, regulating pondage water quality.
As a kind of preferred version of the present utility model, described anaerobic pond adopts efficient UASB reactor, and the pond body degree of depth is 7.4-7.6 rice.
As a kind of preferred version of the present utility model, described Aerobic Pond leading portion is biological selecting area, and back segment is Aerobic Pond aeration zone.
Compared with prior art, the utility model can remove the most of oil lipid material in waste water by air supporting, larger molecular organics is decomposed into small molecules by acidication technique, facilitates follow-up anaerobic technique.Equalizing tank and hydrolysis acidification pool are built jointly simultaneously, reduce floor space, improve pond body effective rate of utilization.Anaerobic pond adopts efficient UASB reactor, and load is high, effective, stable, and can produce a large amount of biogas as new forms of energy reuse.Aerobic process adopts simple A/O technique, effectively reduces the indexs such as COD, improves effluent quality, reduces the pollution to environment, improves the quality of people's living environment.The utility model technique is simple, and processing cost is cheap, and the sludge quantity of generation is few, and purification of waste water successful can be widely used in the process of ice cream factory effluent.
