After the big earthquake of wenchuan, all the county peoples have raised a upsurge about supporting the disaster area to renew life and manufacture, sanitation epidemic prevention after disaster is one of the pivotal work, epidemic prevention after huge disasters be paid great attention.
At present, the emphasis in disaster area is to expedite the temporary buildings and help them settle down in new places. Public sanitary arrangements leaved a lot to be desired because of the huge earthquake, which caused serious, wide area and disaster relief workers. Consequently, by using biogas to deal with the dejection in settled area is to be one of the effective ways. So we provided some forums according to the different cases and numbers in the settled area.
1. Public toilets equipped with biogas pool
According to the sanitary arrangements in settled area, one public toilet equipped a 50 cubic metres biogas pool to deal with the mucky public toilet. Biogas be used for illumination and common life, dregs and liquid to be used for agriculture producing as fertilizer.
2. First find a place to practice, then promotion.
First select a place to practice fast, providing experience and ways for promotion. due to the sustained aftershocks, we had the difficulty in restoring production and common life, building the public arrangements. Not excepting the biogas pool that was a great airproof establishment. Consequently, we first establish a place, it is necessary to optimize choices for technics, construction of pool, adaptability and using management, summing up the experience at the base of the practice and providing credible gist for promotion.
3. Initiatory choice to pool
After the huge earthquake, afterquake is likely to be occurred, in addition, the topography is very complicated, the government built a lot of temporary buildings to help them to settle down. In this case, when selecting pool should fall within the following principia:
1) structure costs cheap, easily to be promoted
2) easy and fast to install
3) saving time, power and materials to avoid contesting manpower and materials with the disaster area rebuilding, reducing the numbers of installation to avoid consuming more delicatessen and items in daily.
4) easy to move, when temporary disasters be moved, these establishment would be easily backouted.
5) adopting soft commercial biogas pool to reduce the transportion stress for disaster area. The pool that have the advantage of small volume, easy to transport and install, and moving convenient.
4. Executive plan for technics structure
1) disaster area at high altitude and the difference in temperature between the day and night there is very big, so we should adopt the three-in-one mode, that is to say make the public, biogas and greenhouse be combined in order to make biogas has a vital role to play in the life.
2) the biogas pool structure should be simple in order to easy to be installed and used.
3) selecting soft materials so that not be destroyed in case of afterquake, to make sure that can be used at unsteadiness .
4)the outlet port made up with PVC materials in order to make the outlet port easy to be fixed and used, making the biogas pool once installed can be used as soon as possible.
5) greenhouse has no skeletal structure, we can directly put the stalk onto the biogas pool, then covered a dark membrane or transparent membrane.
6) in order to admit light and preserve heat, we laid the toilet on the south side and biogas pool on north of the toilet, the floor plan as follows:
5. Implement the place
Be implemented by the disaster area relevant department, the first place implement outlay can be sovled by Beijing Fei Nie Er Technology Ltd. and relevant company. |
