No ke aha ka hopena nui o ka wai paʻakai paʻakai kiʻekiʻe i nā microorganism?

E wehewehe mua kākou i kahi hoʻokolohua osmotic pressure: e hoʻohana i ka membrane semi-permeable e hoʻokaʻawale i ʻelua mau wai paʻakai o nā ʻano ʻokoʻa. E hele nā ​​mole wai o ka paʻakai paʻakai haʻahaʻa i loko o ka membrane semi-permeable i loko o ka hopena paʻakai kiʻekiʻe, a e hele pū nā mole wai o ka paʻakai paʻakai kiʻekiʻe i ka membrane semi-permeable i ka hopena paʻakai haʻahaʻa, akā ʻoi aku ka liʻiliʻi, no laila e piʻi ke kiʻekiʻe o ka wai ma ka ʻaoʻao paʻakai kiʻekiʻe. Ke hoʻohua mai ka ʻokoʻa kiʻekiʻe o nā pae wai ma nā ʻaoʻao ʻelua i ke kaomi ʻana e pale i ka kahe hou ʻana o ka wai, e pau ka osmosis. I kēia manawa, ʻo ke kaomi i hana ʻia e ka ʻokoʻa kiʻekiʻe o nā pae wai ma nā ʻaoʻao ʻelua ʻo ka osmotic pressure. ʻO ka ʻōlelo maʻamau, ʻoi aku ka kiʻekiʻe o ka paʻakai paʻakai, ʻoi aku ka nui o ke kaomi osmotic.

ʻO ke kūlana o nā microorganisms i loko o ka wai paʻakai e like me ka hoʻokolohua osmotic pressure. ʻO ke ʻano hui o nā microorganisms he mau pūnaewele, a ua like ka pā hale me ka membrane semi-permeable. Ke emi ka chloride ion concentration ma mua o 2000mg/L, ʻo ke kaomi osmotic e hiki ai i ka pā kelepona ke kū ʻo 0.5-1.0 atmospheres. ʻOiai inā loaʻa ka paʻakikī a me ka elasticity o ka paia o ka cell cell a me ka cytoplasmic membrane, ʻaʻole ʻoi aku ka nui o ke kaomi osmotic e hiki ai i ka pā kelepona ke ʻoi aku ma mua o 5-6 mau ea. Eia nō naʻe, ke piʻi aʻe ke kaomi osmotic ma kahi o 10-30 mau ea. Ma lalo o ke kiʻekiʻe osmotic pressure, e komo ka nui o nā molekule wai i loko o ka microorganism i loko o ka solution extracorporeal, e hana ai i ka dehydration cell a me ka plasmolysis, a i nā hihia koʻikoʻi, e make ka microorganism. I ke ola o kēlā me kēia lā, hoʻohana ka poʻe i ka paʻakai (sodium chloride) e ʻohi i nā mea kanu a me nā iʻa, hoʻomaʻemaʻe a mālama i ka meaʻai, ʻo ia ka hoʻohana ʻana i kēia kumu.

Hōʻike ka ʻike ʻike ʻenehana inā ʻoi aku ka nui o ka chloride ion i loko o ka wai ʻino ma mua o 2000mg/L, e kāohi ʻia ka hana o nā microorganisms a e hāʻule nui ka COD removal rate; ke ʻoi aku ka nui o ka chloride ion i loko o ka wai ʻino ma mua o 8000mg/L, e hoʻonui ʻia ka nui o ka sludge, e ʻike ʻia ka nui o ka pua ma ka ʻili wai, a e make nā microorganisms kekahi ma hope o kekahi.

Eia nō naʻe, ma hope o ka mālama ʻana i ka wā lōʻihi, e hoʻololi mālie nā microorganism i ka ulu ʻana a hana hou i ka wai paʻakai kiʻekiʻe. I kēia manawa, loaʻa i kekahi poʻe nā microorganisms home hiki ke hoʻololi i ka chloride ion a i ʻole ka sulfate ʻoi aku ma luna o 10000mg/L. Eia nō naʻe, ʻo ka loina o ka osmotic pressure e haʻi mai iā mākou he kiʻekiʻe loa ka paʻakai paʻakai o ka wai cell o nā microorganisms i hoʻololi i ka ulu ʻana a me ka hana hou ʻana i ka wai paʻakai kiʻekiʻe. Ke emi a haʻahaʻa loa ka paʻakai i loko o ka wai ʻino, nui ka nui o nā molekala wai i loko o ka wai ʻino e komo i loko o nā microorganism, e pehu ai nā sela microbial, a i nā hihia koʻikoʻi, haki a make. No laila, ʻo nā microorganism i mālama ʻia no ka manawa lōʻihi a hiki ke hoʻololi mālie i ka ulu ʻana a me ka hana hou ʻana i ka wai paʻakai kiʻekiʻe e koi i ka paʻakai paʻakai i loko o ka biochemical influent mau i kahi kiʻekiʻe kiʻekiʻe, ʻaʻole hiki ke loli, i ʻole e make nā microorganisms i nā helu nui.
