The water treatment equipment and auxiliary equipment (inlet and outlet, overflow trough, etc.) of various amusement pools and leisure pools in the water park have many similarities with the design of the swimming pool, but such amusement pools and leisure pools The function and facilities in the pool are far more complicated than the swimming pool, resulting in the shape, water depth, water temperature, circulation time, circulating water volume, various inlet and outlet layouts, structures and water supply and treatment of the various pools. The system and the water supply and drainage system (small circulation system) of various amusement, leisure and water features are more diverse than the swimming pool.
1. The main design parameters of the amusement pool are shown in Table 12-4-1. Main design parameters of each amusement pool
2. Adjustable water supply port DN50, flow rate 5-8m3/(h·piece) overflow port DN50, pool wall return port DN50, flow rate 5-8m3 (h·piece) sputum DN50, flow rate 1-2m3/(h· )
3. Circulating water supply pipe, flow rate 1.0m/s, circulating water return pipe, flow rate 0.7m/s.
4. The amount of circulating water and the number of slides required for the slides are shown in Table 12-4-2. Circulating water volume and number of people on slides and other water equipment
5. Balance the pool volume (1.2~1.35) x single tank volume, 15min backwash water volume: 50m3.
6. The number of people in the water park is 2.2m3, and the maximum number of people designed is 266.
7. Each device accommodates a total of 991 people.
Second, the circulating water system is designed with the same water temperature. The wave pool and the chute pool with a water surface elevation of 0.13m are combined with a water treatment system and a heating system. The water temperature is different, and the children's pool and leisure pool with a water surface elevation of 0.85m are combined. Water treatment system, two heating systems. The water treatment capacity of the two water treatment systems is 200m3/h. The circulating water purification system adopts the parallel forced circulation water supply mode, and the pool water of each pool adopts the counterflow circulation mode, that is, the circulating feed water enters the pool from the bottom water supply port, and then returns from the overflow port, the squeezing device and the water return port around the pool wall. water.
Third, the circulating water treatment process 1. Circulating water treatment process description The water treatment machine room is set at the basement level of -4.08, with a net height of 4.1 rn. Each pool recycles the return water pipe into the human balance pool by gravity (the drop is greater than 0.6m). The three-in-one circulating water pump absorbs water from the pool, pressurizes it and sends it to the ozone mixer. The mixed water passes through the ozone reaction tank (2100mmx3600rnm), multi-media filter tank (zeolite, activated carbon, quartz sand; 2100mmX: 3600mm), tank top and ozone. The eliminator is connected, and after the soda water heat exchanger, the circulating water supply pipe is connected to each pool. A hair concentrator is arranged on the suction port of the circulating water pump, and a flocculant dosing system is arranged in front of the ozone mixer. A Ph adjustment and long-acting disinfection system is arranged at the outlet of the circulating water supply pipe in the machine room, and an automatic chlorine monitoring device is arranged at the end of the circulating return pipe and in the circulation When the pump stops the pump, the water is prevented from flowing back to the control valve of the balance tank, and the heat exchanger is provided with an automatic temperature adjustment device.
This regulation is based on the requirements of the China Engineering Construction Standardization Association (2000) Jianbiao Xiezi No. 36, "Notice on Printing and Approving the Second Batch of Recommended Standards and Revision Plans of the China Engineering Construction Standardization Association in 2000", by Chinese Architectural Design The institute will work with the relevant units to revise the original "Design Specification for Swimming Pool Water Supply and Drainage" CECS14:89.
In the process of revising this regulation, the revision team conducted investigations and studies, carefully summarized the experience since the implementation of the original specifications, and absorbed mature new technologies, new equipment and new materials, drawing on the standards of countries such as Germany, the United Kingdom and the United States. Information and extensive consultations with relevant units and experts.
This procedure is divided into 17 chapters. The main contents of the revision are:
1. The procedure was renamed as “Design Regulations for Water Supply and Drainage of Swimming Pools and Water Amusement Poolsâ€, which expanded the scope of application;
2. Five chapters including new terms and symbols, pool design, water quality monitoring and system control, management and maintenance;
3. Increased water quality sanitation standards for world-class and national-level swimming pools for competition;
4. Revised and supplemented several design parameters;
5. Increased the regulations on the water recreation pool;
6. Deleted a few outdated and misleading provisions;
7. Complement and improve the relevant provisions according to foreign standards, materials and domestic engineering practice. Filter sand tank - application range:
â—Water filtration in swimming pools, water parks and massage pools
â—Seawater, freshwater aquaculture, aquarium engineering, aquarium engineering
â—Industrial water purification, landscape water treatment
â—Prescription of drinking water
â—Agricultural irrigation
