One or more in grain.Wherein, zeolite can be clinoptilolite, sodium modified zeolite etc., and activated carbon can be with Adsorption of Heavy Metals, different
Taste organic matter etc., clinoptilolite, sodium modified zeolite then adsorbable ammonia；Filler can be adjusted according to heat supply network backwater laboratory indexes to live
Property charcoal, clinoptilolite, the ratio of sodium modified zeolite each component.
Further, the aperture of the filter screen is less than the particle diameter of the filler in packing layer.So, filler can on the one hand be avoided
Filter screen is gone out by water, resulted in blockage, on the other hand, filter screen can filter larger mechanical admixture so that water outlet is limpid, and keeps away
Exempt from impurity and be mixed into filler.
Further, the housing is provided with backwash inlet and backwash outlets.Can be right by backwash inlet and backwash outlets
Recoil cleaning is carried out in housing, cleaning performance is greatly improved；Backwash inlet or backwash outlets can discharge impurity as sewage draining exit.
Further, it is equipped with valve on the inlet pipeline and outlet pipeline.Wherein valve is hand-operated valve or automatic valve, is entered
Flowmeter, pressure gauge and/or temperature sensor etc. can also be set in water lines.
Further, it is equipped with valve on the backwash inlet and backwash outlets.Wherein valve is hand-operated valve or automatic valve.
Further, the material of the housing and filter screen is stainless steel or polytetrafluoroethylene (PTFE).Housing of the present utility model and filter
Host will select corrosionproof heatproof pressure-resistant material, and the hot water after heat supply or refrigeration can be filtered, and improve service life, subtract
Number of times is changed less.
Further, the filter screen located at packing layer both sides is individual layer filter screen or multistorey strainer mesh.Wherein multistorey strainer mesh can be with
It is to be folded to be formed or multiple filter screens are spaced and formed by individual layer filter screen.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment 1.
Embodiment
The utility model is described in further details below with reference to Figure of description and specific embodiment.
Embodiment 1
As shown in Figure 1：A kind of heat supply network recycling water utilization processing unit, including a filtration body 1, filtration body 1 include again
