                  太陽能低溫復合膜干化 Solar composite membrane drying at low temperature 利用太陽能作為能源,將含水率80%~85%的脫水污泥均勻布入密閉的太陽能膜箱內,膜箱上表面為高透光率的太陽能低溫復合疏水膜,在太陽光照射下膜箱內溫度升高,與外界形成一定的溫差,污泥吸收熱能后實現水分蒸發,水霧在低溫復合疏水膜表層冷凝成液態水并流至集水管,蒸餾出水可回用或直接排放,得到含水率低于8%的干化污泥。 Use solar energy as an energy source, the moisture content of 80% ~ 85% of the dewatered sludge uniformly into the airtight solar film box, film box on the surface of high light transmittance of solar low-temperature composite hydrophobic membrane, membrane the temperature in the cabinet in direct sunlight, form a certain temperature difference with the outside world, after the sludge absorption heat evaporation, water spray on the surface of low temperature composite hydrophobic membrane to condense into liquid water and flow to the manifold, and distilled water can be reuse or direct emissions, moisture content is less than 8% of dry sludge. 干化過程中污泥物料內水分的蒸發與冷凝均無動力消耗,實現節能環保。污泥處理后的干渣含水率很低,可直接用于制造活性炭,性價比較普通活性炭更高。此外,針對一般污泥中含有的寄生蟲卵這一無害化處理的難題,該工藝通過復合膜技術,不需添加任何輔助化學藥劑,使病原微生物等致病物質在密閉的膜箱空間內,被太陽光紫外線有效處理。金山環保利用該技術已在宜興建立了100噸/天的污泥處理處置項目,并已穩定。 Sludge in the process of drying material moisture evaporation and condensation in no power consumption, energy conservation and environmental protection. Sludge treatment after dry slag moisture content is low, can be directly used in the manufacture of activated carbon, the common active carbon, the higher cost performance. In addition, in view of the general sludge parasite eggs in the disposal of the problem, the process by composite membrane technology, does not need to add any auxiliary chemicals, make the pathogenic microorganisms such as pathogenic substances inside airtight membrane box space, effective processing by ultra-violet rays. Jinshan environmental protection by using the technology have established 100 tons/day in yixing sludge disposal project, and has set up a stable.
