工艺流程 1、埋设于地表以下,设备上面的地表可作为绿化或其他用地,不需要建房及采暖、保温。 2、二级生物接触氧化处理工艺均采用推流式生物接触氧化,其处理效果优于完全混合式或二级串联完全混合式生物接触氧化池。并比活性污泥池体积小,对水质的适应性强,耐冲击负荷性能好,出水水质稳定,不会产生污泥膨胀。池中采用新型弹性立体填料,比表面积大,微生物易挂膜,脱膜,在同样有机物负荷条件下,对有机物去除率高,能提高空气中的氧在水中溶解度。 3、生化池采用生物接触氧化法,其填料的体积负荷比较低,微生物处于自身氧化阶断,产泥量少,仅需三个月(90天)以上排一次泥(用粪车抽吸或脱水成泥饼外运)。 4、该地埋式生活污水处理设备的除臭方式除采用常规高空排气,另配有土壤脱臭措施。 5、整个设备处理系统配有全自动电气控制系统和设备故障报警系统,运行安全可靠,平时一般不需要专人管理,只需适时地对设备进行维护和保养。
Chengdu, June 26, Xinhua News Agency, Chengdu, China (XinhuaNews Agency) - Drug addicts often fail to acknowledge their lack ofcooperation in drug control work. Nowadays, the application of"black technology" in drug control, such as sewage and hairtesting, has greatly improved the efficiency of precise remediationof community abuse of D products.
Recently, Dabei Street, Yanjiang Branch Bureau of G'an Bureau ofZiyang City, Sichuan, sent M police officers, Street office staffand anti-drug social workers to the east section of Binhe Road. Thestreets are densely populated with Y music venues such as KTV andGecheng.
M police arrived at the gate of Y Lecheng named Longxiang,prized the well cap of the sewer, slowly put the sampling bottleinto the sewer several meters deep, and collected the domesticsewage discharged from the sewer. Within 30 minutes, M policecollected samples of domestic sewage discharged from two Yplaygrounds on the street and asked their owners to sign andconfirm the extracts.
What secret is hidden in the sewage?
It is understood that the collected sewage samples will be sentto the D product Laboratory of the G'an Department of SichuanProvince. After a series of pretreatments, they will be put intothe chromatographic monitor for monitoring. With the help ofinstrument analysis, a 0.25 ml sewage sample can detect thetoxicity.
Xu Buyi, senior engineer of D product Laboratory of Sichuan G'anDepartment, told reporters that after D product is metabolized byhuman body, a considerable proportion of residues will still bedischarged into domestic sewage. By measuring the concentration ofD product residues in sewage and combining the data of inflow flow,we can estimate the situation of drug abuse and D product abuseamong the population in this area, and then investigate it. Drugabuse information in the region.
Such technology has practical significance for grassrootsmanagement and control. Yao Xiaojun, head of the anti-drug brigadeof Yanjiang Branch Bureau of G'an Bureau of Ziyang City, introducedthat relying on the technology of "sewage poisoning test" of theprovincial G'an Hall, Yanjiang District began to carry out routinepublic sampling and monitoring of the sewage pipelines of keyY-place in the area under its jurisdiction. If the toxicity indexof sewage sampling data is abnormal, it will be directly listed asthe key place of red card treatment. While strengthening theinspection, organize the staff to squat around and arrange untilthe source is found out.
"In the past, we managed the drug-related situation in Y Place,mainly by door-to-door inspection." Zhang Jian, a community Mpoliceman who carried out the sewage sampling, said, "Temporaryinspection is not only time-consuming and laborious, but alsolimited in the number of spot checks, some of which are not easy tograsp."
In addition to the sewage drug testing, a special physicalexamination was held in the Shutai community of Songtao Town,Yanjiang District. More than 10 people who are carrying out drugrehabilitation and rehabilitation in the community conducted hairsampling and drug testing in the newly built "testing room" of thecommunity drug rehabilitation center.
Morphine and monoacetylmorphine were detected in the hair ofChen Moumou, a community rehabilitation worker. He denies in everyway, insists that he did not take D-products, and his attitude isbrutal, trying to evade punishment by means of zero confession. ButChen Mou-mou did not succeed. He violated the communityrehabilitation agreement and was forced to isolate and detoxify byYanjiang Branch Bureau of G'an Bureau of Ziyang City.
"Before the use of urine tests, can only detect whether thesubject within a week of drug use, now with hair testing, even sixmonths ago, drug use, but also can be found out." The staffsaid.
