"Mainly there are three kinds of drinking water sources of masses in the disaster area at present: Running water, underground well water, mountain spring. The running water is purified and sterilized in unison by the water plant, we are most easy to monitor water quality, its safety coefficient is the highest in three kinds of water. " The environmental sanitation subject section chief Li ZhiChun of Center for Disease Prevention and Control in Chengdu says. How does the water plant pay sterilizing and purify to the running water? How to monitor the situation of its water quality? Yesterday, the reporter was on the first waterworks of market of Dujiang Weir, the disinfection witnessing water of source of water turned into the drinking water purified the whole course. Sterilize after purifying 8 times the running water can be drunk directly According to the introduction of Li ZhiChun, the population above the Dujiang Weir urban area 90% has already used the running water at present, it is Dujiang Weir first, the second water plant to supply water, two water plants supply water of more than 45000 tons every day; Among them water of source of water of the first water plant is taken from Ming river, water of source of water of the second water plant is taken from the groundwater. "Enter the water pipe here, we sterilize water of source of water for the first time when into water pipe. " Luo Chong, factory director of first waterworks Dujiang Weir, points to two water pipes of about 40 centimetres in diameter and says in autumn, the chlorine dioxide generator will inject the liquid chlorine dioxide into these two and enter the water pipe, sterilize for the first time; What water which has added the chlorine dioxide is reached next is the sediment pool, after flowing through six sediment pools, some grains of sand will be precipitated. The reporter has a water outlet to notice the corner of each sediment pool, there are small water pipes above the water outlet, the small water pipe has been input in the water outlet all the time " Flow trickling sluggishly and thinly " . "It was coagulant that the pipe flow of small water came out. " Luo Chong says in autumn, will the chemical reaction arises with some materials in water in coagulant, water with coagulant is entered and stired the pool, let coagulant be fully mixed with water next, professional term ask " The reflux reacts " ; After stiring the pool, water enters and precipitates the pool, let the particle in water precipitate. The reporter sees, water precipitated in the pool is a little more limpid than water of source of water, but been covered with tiny particles as dust. "Water precipitating the pool enters the oblique tube to strain the pool, filter the tiny particle in water again. You see whether water that the oblique tube strains inside the pool is much more limpid. " Luo says loftily, the principle that the oblique tube strains the pool is that the bottom of the pond is alveolate and oblique managed, oblique tube as long as one, water emit, come up now from oblique tube, particle will enclose in oblique to in charge of bottom, water after straining the pool through the oblique tube is the semi-manufactured goods. After straining the pool through the oblique tube, the water plant sterilizes water with the chlorine dioxide again, then send out. "Through 8 processes, our water can well reach the national drinking water standard, can drink directly even. " Luo Chong says in autumn, because of may have situation of pollution to give water a pipelining, so he advises the masses not to drink the unboiled water. Monitor water of factory out every measuring once every 1.5 hours strictly After first waterworks comes out to Dujiang Weir, the reporter comes to the second waterworks Dujiang Weir. "The intersection of source of water and water of us taken from groundwater, but procedure purified to sterilize 8 pass too. " Inspector Kou YuJuan of water quality says, on the basis of sterilizing regularly and purifying, water plant have one's own laboratory, produce water of factory, pay and take a sample to examine to the intersection of source of water and water every 1 and a half hours, mainly examine turbid degree, pH value, my chlorine content, ammonia nitrogen, total number of bacteria, total large intestine fungus group of water,etc.. The reporter notices the bandit put a thick one examining the record in front of having beautiful jade, the results examined each time are all recorded above, the newest test data are 30 past 12 " turbid degree of water of source of water is 0.19, produce factory water turbid degree 0.16, over chlorine content 0.23 " ,Standard that country stipulate exceed 1 for produce the intersection of factory and the intersection of water and turbid degree, over the intersection of chlorine and between 0.1 and 0.8 content. "Except that we examine by oneself, the personnel that disease accuses of the centre will fetch the water sample to monitor every day, in order to totally guarantee water quality's security. " Kou YuJuan says, checked and monitors water quality, there are the staff members of personnel of Health Inspection Institute and Chinese Health Ministry besides accusing of personnel in disease. The security villages and towns rebuild the small urban area of water plant and use the safe running water to protect and drink the water, where are the masses on the villages and towns? Li ZhiChun introduces, 19 waterworkses of villages and towns, already 16 have resumed supplying water at present, among them it is a newly-built water plant to the high township waterworks. Li ZhiChun says, before shaking, very simple and easy to the water plant of the high township, after residents sterilized the mountain spring briefly, smoke to the water tower, then supply every family. But unable water supply that the earthquake makes this simple and easy water plant destroyed seriously. Under the aid of the French friend, on May 22, built up a new water plant of 50 tons for a piece of water of Nissan to the high township, have solved nearly 3000 persons' drinking water problem in the town. The water quality of this water plant is totally qualified too through measuring, even can drink directly. In Peng Zhou's new developing town, a new waterworks has already built up too. Chen Jun that disease in Chengdu accuses of central environmental sanitation subject introduces, the water plant of the new developing town is a source of water looked for by the municipal water affair office in the Peng 's, totally qualified through measuring. On June 2, this water plant all apparatuses assemble and finish, is laying the stylograph at present, will come into operation on this day, can solve about 10,000 persons of drinking water problems in the town.
