???? xinhuanet.com Beijing on 31 March, (reporter Ma Shurui) for centralized treatment of sewage treatment plant of the response to water, is the essence of environmental protection facilities, but the emission index is unqualified exists is Cheap Jets Jerseys a problem throughout the environmental protection facilities, which makes a "source of pollution".

???? Huainan is the first plant disinfection facilities is not running the sewage treatment water Co. Ltd. in outlet sampling, monitoring results, the treatment plant drainage of ammonia nitrogen in 11.4mg / L, exceed the standard 0.425 times, fecal Cheap Panthers Jerseys coliform is greater than 24000 / L, exceed the standard 23 times above.

???? in Anhui province in 2013 4 quarter state-controlled sewage treatment monitoring results also showed that the plant supervision, Bengbu City, the first sewage treatment plant, Tongling Xinmin sewage treatment plant, Tongling city West Lake sewage treatment Co. Ltd., Fuyang capital water Co., Ltd. fecal coliform emission is not up to the standard, Huaiyuan county sewage treatment plant discharge not up to the standard of the Yangtze River, Anhui province and County Environmental Engineering Co., Ltd. COD emissions are not compliance.

???? Wang Jiaquan professor of College of resource and environment engineering, HeFei University of Technology, the causes of this situation from a technical perspective, mainly is the old factory in the design is not in accordance with the existing one class a discharge standard of design, construction, operation. "For example, the most common fecal coliform index, emissions is needed to do a final disinfection procedures before discharge,, but some factory Cheap Cardinals Jerseys or when the design of disinfection facilities not up to current standards, or sterilizing dose delivery problems, process or facilities do not meet, resulting in exceed the standard discharge." In addition, season, management, maintenance of equipment will affect the quality of sewage treatment, but also directly affects the discharge of the qualified or not.

???? the second is human factors, such as management is not in place, Cheap Bears Jerseys the equipment stability is poor, especially some human do not pay attention to the various laws and regulations, technical standards, not implement non execution.

???? Wang Jiaquan analysis said: "with the index of fecal coliform bacteria as an example, the new technique using ozone for disinfection, but the cost is high, a lot of sewage treatment Cheap Chiefs Jerseys plant in order to reduce the cost, more profit, not the use of ozone, or reduce the dose, the artificially lower standard, non-standard operating or not update technique, which is an important factor in the sewage treatment is not up to the standard."

???? how to solve these problems? Anhui Provincial Department of housing and urban rural development city construction department researcher Zhang Jingyu think, first of all is the sewage treatment plant to part of the early construction of the mentioned standard renovation, require treatment to achieve discharge standards as soon as possible.

???? it is reported, not only in Anhui, many provinces of the existing sewage treatment enterprises, basically are built in accordance with the national standard B class, to reach the new emission standards for a class a standard, it is necessary to the sewage treatment plant mentioned standard renovation. Relying on the process and level of existing, very difficult to achieve a stable discharge standards.

???? Zhang Jingyu said, in recent years Anhui has been working on this part of the sewage disposal plant of standards upgrading, >
