Background technology
Introduce the tap water of building from city water-supply pipe network, its water quality generally all meets the requirement of " drinking water sanitary standard ".But, if the design of building interior water supply system, construction or safeguard improperly all the water pollution once again phenomenon possibly occur.According to statistics, China is the proportion of water pollution in the residential community scope in the second pressure water supply system that has water tank (pond) at present, accounts for 70% of whole water system secondary pollution.Output water that certain urban district was once detected and pipe network water water quality data are like table 1.
Certain district's secondary water-supply of table 1 is with water spot and go out water factory's water quality contrast
Figure BDA00001727211200011
Can find out that from table 1 turbidity of secondary water-supply has changed 6.4 times, total number of bacteria has changed 13.27 times; Two indexs all are far longer than out the index of water factory; Residual chlorine amount has also changed 8.5 times, so the water pollution that causes of secondary water-supply, can directly endanger the people's health and lives.So, carry out building water supply water quality protected working, prevent secondary pollution, be a very important job, must cause enough attention.
The problem of high level cistern existence at present mainly contains following problem:
1, material such as tank box and component is unreasonable, and facility all wears out, and iron rust, chip cause yellow water, muddy water phenomenon, severe contamination water quality.
2, the waterbox design capacity is excessive, makes water time of staying in case long, and the free chlorine major part is diffused in the air, organic matter condenses upon internal face, can cause bacterial reproduction, moss growth, egg hatch.
3, there is the slough in water tank, and water flow disturbance is little, is prone to cause bacterial reproduction, the hatching of red worm etc.
4, the overflow pipe design is unreasonable, and airborne harmful germ can enter into the secondary pollution that causes water tank in the water tank.
The secondary pollution of existing control attic tank mainly contains following several method:
(1) adds chlorination equipment
The sterilization of water tank generally has: 1. on the outlet pipe of water tank, establish ultraviolet ray disinfector; 2. electrolysis hypochlorite generator; 3. electrolysis chlorine dioxide compound disinfectant generator; 4. the self-cleaning sterilizer of water tank.
First method is to utilize the physical disinfection process of ultraviolet ray to bacterium, and it is short to have disinfecting time, advantages such as the poisonous and hazardous DBPs of not association.Second and third kind sterilization method still is to be main sterilization method with chlorine, is that main composite disinfectant gas is batched in the drinking water in proportion with the clorox that produces or with chlorine, and kill bacteria also keeps suitable residual chlorine amount.The 4th kind of method is more commonly used at present, and reason is that self-cleaning sterilizer does not add any allogenic material in water, and it is the effect of playing sterilization and algal control by oxidation material that the little electrolysis of circulation produces, is applicable between the water tank of negligence of management.
" Code for design of building water supply and sewerage " (GB50015-2003) the 3.2.13 bar regulation is arranged, the Drinking Water case should be established disinfection unit in the time can not obtaining upgrading in 48 hours.But in design, in most cases satisfy the requirement of upgrading in 48 hours far away, generally need not establish chlorination equipment.But for the special place of easy generation pathogen contaminations such as medical institutions, perhaps from emergent angle, it still is necessary that water tank is provided with disinfection apparatus, but must carry out maintenance and management at ordinary times.
