Although above-mentioned patent has played purification to a certain degree to sanitary sewage, if but how the water purification after processing is applied unresolved, and for different applied environments, it can not directly meet water requirement, so just need to a kind ofly can directly meet particular demands and effective Sewage treatment systems.
Utility model content
The purpose of this utility model is for the technological deficiency existing in prior art, and a kind of sewage treatment unit of the water charging system that is applicable to freeze is provided.
For realizing the technical scheme that the purpose of this utility model adopts, be:
A kind of sewage treatment unit of the water charging system that is applicable to freeze, comprise the water tank being communicated with sanitary sewage water inlet pipe, the topping-up pump being communicated with successively by the road, ultra-filtration equipment, intermediate water tank, middle water pump, full-automatic softening agent, softening water tank and small pump, wherein, the water inlet pipe of the backwashing pump of described ultra-filtration equipment is communicated with intermediate water tank, and the water outlet of described small pump is communicated to refrigeration water charging system by the road.
Described small pump is two small pumps that are arranged in parallel.
On the pipeline being communicated with the water outlet of small pump, be provided with constant pressure water compensation apparatus.
Compared with prior art, the beneficial effects of the utility model are:
The sanitary sewage that the utility model utilization produces is at any time as refrigeration moisturizing, and sanitary sewage discharge is basic directly related with the work of refrigeration system, and the exhaust temperature substantially constant of sanitary sewage and maintenance low temperature, can effectively meet refrigeration moisturizing demand.And the processing through necessary, effectively reduces refrigeration cost, save water resources, realized sewage recycling.
Accompanying drawing explanation
Figure 1 shows that the sewage treatment unit structural representation of the water charging system that is applicable to freeze of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, sewage treatment unit of the present utility model comprises the water tank 1 being communicated with sanitary sewage water inlet pipe, the topping-up pump 2 being communicated with successively by the road, ultra-filtration equipment 3, intermediate water tank 4, middle water pump 5, full-automatic softening agent 6, softening water tank 7, small pump 8 and constant pressure water compensation apparatus 9, wherein, the water inlet pipe of the backwashing pump 10 of described ultra-filtration equipment is communicated with intermediate water tank.Wherein, to be all that PLC is controlled with the control part of Sewage treatment systems be connected above-mentioned each parts, by PLC, automatically controls, and controls each assembly and be arranged on the work such as magnetic valve of each assembly.Meanwhile, be also respectively arranged with high-low-position sensor on described intermediate water tank and water tank, it feeds back to PLC to carry out overall security control by water level information.
Wherein, the sanitary sewage entering in water tank is the sanitary wastewater that reaches national secondary discharge standard, according to the water quality situation of different areas and biotope, can before water tank, increase corresponding pretreatment unit, for the water treatment device in later stage provides water quality guarantee.
Described ultra-filtration equipment is four ultrafiltration modules in parallel, and wherein ultra-filtration equipment is a kind of membrane separation technique, and the solvent containing in feed liquid and various little solute see through filter membrane from high pressure feed liquid side and arrive low-tension side, thereby obtains seeing through liquid or being called ultrafiltrated; Its ultra-filtration membrane micropore can reach below 0.01 micron (100,000/millimeter), can effectively remove under particulate, colloid, bacterium, thermal source and the effect of organism power in water, and the size solute molecule tunicle larger than membrane pore size is held back into concentrated solution.The utility model arranges four ultrafiltration modules in parallel, improved its water treatment capacity, when specific works, can control alternation between two by PLC, two can guarantee the lasting generation of water purification two of water purification like this in backwash, certainly can control its water purification or backwash simultaneously, can meet so a large amount of water demands in certain hour, the water inlet pipe of its backwashing pump is connected to intermediate water tank simultaneously, utilizes processing water to carry out back flushing, when guaranteeing its normal operation, reduce water resource waste.
Water hardness is mainly by positively charged ion wherein: calcium (Ca2+), magnesium (Mg2+) ion forms, if whose much higher hard, for cooling cycle system, can cause detrimentally affect, so soften processing, when the former water that contains hardness passes through full-automatic softening agent, calcium in water, magnesium ion is by resin absorption, discharge sodium ion simultaneously, the water flowing out in interchanger is like this exactly the softening water that has removed hardness ions, when resin absorption calcium, magnesium ion reaches after certain saturation ratio, going out water hardness increases, now water softener can carry out the reproduction operation of exhausted resin automatically according to preset program, utilize the sodium chloride solution (salt solution) of higher concentration to pass through resin, make the resin losing efficacy again return to sodium type resin.Concrete full-automatic softening agent can adopt commercially available prod, does not repeat them here.
For guaranteeing aquifer yield, described small pump is two parallel designs, has increased moisturizing power, improves the running stability of refrigeration system.Be arranged on the constant pressure water compensation apparatus on described small pump outlet pipeline simultaneously, can effectively improve the stationarity of draining, eliminate noise and water hammer,
