The accomplishments within this project (year 2005) were briefly listed as the followings:
1.Night-soil quantity generation and flow tracking survey was conducted in 156 train stations, 43 public transportation companies, 30 prisons, and 11 airport terminals domestically.
2.To assist each agency clearly controls the night-soil quantity generation and disposal quantity, we referred to the executive experiences in Taipei and Taichung to create night-soil generation source management mechanism, and separated enlisting target businesses into different stages for manifest reporting.
3.We studied the existing 5 night-soil treatment facilities, in terms of executive condition by 10 analyses, and suggested improvement strategy.
4.We offered relevant information regarding industrial sewage treatment facilities, leachate (including night-soil) treatment facilities for landfill, night-soil sewage pipe within sewage treatment facilities to the responsible agencies for planning night-soil treatment facilities.
5.Most local night-soil treatment facilities have limited treatment capacities, except Taipei City. Keelung, Sindian, Sanchong, Hsichih, and Yonghe are available to offer limited assistance on treating night-soil; hence cross-region disposal is not suitable in the existing condition.
6.Night-soil contains low solid content, high water content, and hard to use it as fertilizer alone. It is suitable to mix night-soil with other organic waste, like mixing with kitchen residue to generate methane gas for electricity generation.
7.To resolve the problem of limited availability of night-soil treatment facility, long disposal route, and high cost, establish night-soil heating and disinfection equipment in existing landfill located in rural and agriculture area will offer a resolution.
8.Provide suggestions for the amendment and review of relative regulations, management mechanism according to the survey conducted locally.
9.Invite scholars to 25 local environmental agencies to supervise the effectiveness of the night-soil management, and provide improvement suggestions.
10.Establish “Night-soil Proper Disposal Promotion Auditing System” to let the responsible personnel report predetermined executive schedule, content, and result of operation quarterly, in order to trace progress of the operation.
11.Five training sessions were held in Taipei, Taoyuan, Changhua, Taichung and Kaoshiung to convey correct night-soil disposal operation principles.
The major problem facing by the night-soil disposal is limited availability of the night-soil treatment facility. IT will be difficult to promote proper disposal and legitimatize the disposal facilities. Subsidizing each local agency and establish night-soil treatment facility is the most important resolution. Also, EPA will actively integrate the existing resource and other central competent authorities to resolve the problem.
