Description

Swimming-pool water recycle biochemical treatment apparatus
Affiliated technical field
The present invention relates to a kind of swimming-pool water circularly purifying process field swimming-pool water recycle biochemical treatment apparatus.
Technical background
Swimming is the activity that improves the health that liked by China broad masses of the people, and active effect has been brought into play in the natatorium for the people builds up health.But, the circular water treating system that the natatorium is traditional, exist sterilization not thoroughly, many drawbacks such as water resource waste and contaminate environment.
1) traditional natatorium circular water treating system adopts pressure filter (sandfiltration pot) more, Chi Shui is purified, behind the pressure filter work certain hour, filtering sedimentation of suspension layer is thickeied gradually, influence filtration efficiency,, need carry out back flushing with the tap water of cleaning in order to overcome this phenomenon.By normal tour swimming pool water capacity 4500m 3Calculate about 150m of water consumption of back flushing 3, the whole nation has 2.2 ten thousand natatoriums approximately, and annual back flushing consumes about 11.9 hundred million m of tap water 3, be equivalent to 1/4 of Miyun Reservoir water storage, the water consumption in 1 year of medium-sized city resident.If by 5 yuan/ton of average water rates, 1 yuan of/ton calculating of effluent charge, 71.4 hundred million yuan of the annual losses in national natatorium.Backwashing sewage water directly discharges water drain, calculates with MLSS=250mg/L, and discharge pollutants 29.75 ten thousand ton to society every year.
2) traditional natatorium circular water treating system disinfection way adopts chloridized more, and sterilizing agent commonly used has liquid chlorine, chlorinated lime etc., perhaps uses hypochlorite generator, salt acid system dioxide peroxide compounding disinfection and ozonizer etc.The toxicity of chlorine is bigger, in a single day reveals in the use or injected volume meeting out of control crisis HUMAN HEALTH.Hypochlorite generator's electrode is fragile, and power consumption, salt consume higher.Though dioxide peroxide and chlorine gas mixture that the salt acid system produces can reach the disinfectant purpose,, chlorine is easy to generate trichloromethane, and it is a kind of carcinogenic substance.Can cause when ozone reaches 1ppm in air and symptom such as breathe quicken, uncomfortable in chest, reach 2.5-5ppm and stop and to cause pulmonary emphysema in.And this facility investment costliness, floor space is big.
Summary of the invention
For solve sterilization that traditional natatorium circular water treating system exists not thoroughly, problems such as water resource waste and contaminate environment; the present invention proposes the biochemical cyclic processing device of a kind of swimming-pool water thing; physics, biology, three kinds of treatment processs of chemistry organically are combined into three grades of complete cyclic processing devices, have realized the backwashing water reuse---conserve water resource, sewage zero-discharge---protection environment, thorough disinfection---three general objectives of safety and sanitation.
The technical solution adopted for the present invention to solve the technical problems is:
1) one-level circulation
The swimming pool discharge water at first carries out filter just, removals such as floating matter that will be bigger, hair through hair interceptor.Just the discharge water after the filter is filtered by pressure filter, and the clear water after the filtration is sent into swimming pool after being sterilized by the disinfection by chlorine dioxide machine.Reach the disinfection indicator of GB5749-85 " drinking water sanitary standard " regulation through the swimming-pool water after the sterilization of disinfection by chlorine dioxide machine.Treatment unit is finished the one-level circulation.
The disinfection by chlorine dioxide machine is the gas chlorine dioxide generating device, and this equipment adopts sodium chlorate and sulfur process, selects safety and stability, nontoxic, permanently effective for use, and the reductive agent that reacts with empty G﹠W is not soluble in water, solution-stabilized, the ClO that reaction generates 2Purity is not less than 95%, has realized that the reaction solution continous-stable adds ClO 2The gas continous-stable takes place.Body adopts materials such as titanium, polymer alloy, macromolecule resin, has solved problems such as requiring physical strength height, heat-resisting and resistance to chemical attack, makes this equipment safe and reliable to operation.
Chlorine dioxide is dissolved in the water by water jet absorption, is back to swimming pool and mixes with water body and reach the disinfectant purpose.The chlorine dioxide sterilizing agent is used for swimming sterilizing by the AI level high effect disinfectants that The World Health Organization (WHO) is confirmed to be a kind of safety, wide spectrum, non-secondary pollution: 1) disinfecting power is strong, dosage is low, effective.Noresidue in sterilizing process does not produce secondary pollution.2) solubleness in water is 5 times of chlorine, does not decompose, non-volatile, and sterilisation effect is not subjected to the influence of pH value, and the length of holding time has no side effect to human body.
2) secondary circulation
Behind pressure filter work certain hour, filtering sedimentation of suspension layer is thickeied gradually, when influencing filtration efficiency, and the pressure transmitter output command of strainer: stop to filter and unlatching tap water recoil water valve, pressure filter is carried out back flushing.Backwashing sewage water input water tank, administration device adds in an amount of flocculation agent and suspended substance electric double layer surface charge to water tank, reduce intergranular repulsive force, condense into cotton-shaped suspensoid rapidly, injecting the homogeneous pond by recycle pump again carries out modified, modified back sewage input biological moving bed oxidation pond, throw in through preferred microorganism in the oxidation pond and tame postvaccinal biological film suspend carrier, aerator provides sufficient dissolved oxygen to oxidation pond, suspending carrier impacts conpound salto next time then free-floating at the aeration lifting force and moves, make microbial film fully contact dissolved oxygen and organism in the water body, improve the biochemical degradation ability.This biological film suspend carrier biofilm speed improves more than three times than general floating stuffing, and microbial film is thin, is difficult for stopping up, and the microbiological deterioration ability is strong, water outlet COD clearance 〉=90%, BOD clearance 〉=98%.Mud mixed liquid is handled the back through microbiological deterioration and is injected settling tank, and precipitating sludge is transported to modified pond by sludge return pipe and carries out denitrification denitrogenation.Mixed solution behind the biochemistry is transported to the physics membrane separation apparatus.This process makes the backwashing water of pressure filter obtain advanced treatment, avoids discharging, has saved great amount of water resources.Treatment unit is finished the secondary circulation.
3) three grades of circulations
Mixed solution behind the biochemistry is under the jet flow negative pressure effect that recycle pump produces, the auxiliary agent of auxiliary agent throwing device set amount is filmed to physics membrane separation apparatus filter element medium by multiway valve, film and enter the solid-liquid separation process after finishing, separation accuracy 〉=1 μ m, clear water after the separation, counterbalance cell is sent in sterilization through the disinfection by chlorine dioxide machine, and then the input swimming pool.
Behind the physics membrane separation apparatus work certain hour, composite membrane absorption mud thickness on the filter element medium is increased to when influencing filtration efficiency, the pressure transmitter output command of separator, multiway valve is changed former water water inlet direction, carrying out back flushing rinses out composite membrane on the filter element medium and dirt, backwashing sewage water enters sludge treatment equipment through multiway valve, handles recovery.In back flushing, separator is finished and is oppositely filmed for the second time, film finish after, multiway valve resets and recovers the solid-liquid separation process.Backwashing sewage water is handled the back through sludge treatment equipment and is reclaimed, and reaches the purpose of sludge zero discharge and protection environment, and treatment unit is finished three grades of circulations.
