2006/5/2 General thinking about my "Water Planning".Water waste has become a big deal to China,not only because of the big population,but the wrong thinking of water also.So saving water is a necessary task to the world.But saving in factory,that is,by industry way,is too far away from me,and I believe there must be something they can do to limit the water use.On the other hand,amount of water used in family way is much greater than factories do.Moreover,the number of ways in using cause a lot of recycled spaces,e.g.water used to wash fruits can be reused in gardening.
Following,list out the ways of using water:
◆Washing room use:
①Used in washing hands,face,clothes(washing machine),or taking showers.
Water after these kind of using are not polluted so badly so can be well-recycled.This kind of water always contains the remainder of soaps,which is called soapsuds.I think here the PH value may be relatively higher,neutralization is needed.Other chemical can be decomposed in chem. ways,I'll test the possible compounds in water later and give solutions.Additional,nowadays,the daily use are more and more harmful to humans,like perfumes and some men-use,so if the faces washed carrying these things,better ways need to be carried out here to make them less harmful to us.
②Used in cleaning the excretion of humans or pets fed in family.
Personally thinking,to clean this kind of water is almost the hardest in all kinds of water in family use.Thought to be the dirtiest,actually it mainly contains urea(A water-soluble compound,CO(NH2)2,that is the major nitrogenous end product of protein metabolism and is the chief nitrogenous component of the urine in mammals and other organisms.[also]carbamide---explained by AHD),and the mixture is complex,but bio-decomposition may be available to this situation,the thing is,how to identify the different kinds of organisms?Information collecting&technical help is needed here.
◆Gardening use: ①Used in planting. Here is much easier,because plants don't absorb all the water we give them,the remaining become a waste if we don't deal with it.Like flowerpot,we can make a special net seperating sands the stones from water,after this,collect the clean by a pipe or something.But it seems not so necessary here,or if there is a fish pool,just connect them together? ②Used in fishing pool. Seems hard to reuse water here because fishes better live under an open condition,almost impossible and useless to collect the vaporized water,so maybe here can be made to be a final destination of water,i.e.all the water that hard to recycled anymore can put into the pool if the family has one,a little bit cruel to the fishes.I'll think of another better way. ◆Kitchen use: ①Used in washing rice,vegetables,fruits,etc. Here I think water waste most coz almost clean,but now we just let them flow away.And this kind of water is easy to be cleaned,but the technical difficulty is the pipes,that is,how to deal with the water,store it?Use a tank? ②Used in washing dishes. This is relatively harder,containing detergent and oil mixture,always appear as a base.Can we just seperate water and oil by the density differences?seperate layer?Experimental effort is needed here. ③Used in cleaning meats,like chicken,anything bloody things. Blood,which is the bio things,not harmful,but the viruses carried by the meats should be take into consideration.Maybe high temperature is helpful here,around 353K is enough for killing the mojarity viruses.
According to the analysis above,seems the most difficult part is dealing with the chemical and the whole system setting.Different houses have their own structures,so fixed pipes and recycled sections are not available in this plan.And how to store the water after cleaning?Simply by a tank?But again from tank to pipe we transmit the water by what?Pressure?If that so,the cost of setting the system is high,which is meaning hard to be popularized.
All in all,the general goal of this "Water Planning" is to make up a system for different kinds of houses which can save water by adding pipes and simple machines.Keep the cost of the system cheap and useful,better it's so worthy and convinent that every family use it.And don't just satisfy with 2-time use of water,as many as possible.If all these happened,water would be saved in a amazing speed. 引用通告此日志的引用通告 URL 是： http://forrestsun527.spaces.live.com/blog/cns!3597A22EF49D2DB0!109.trak 引用此项的网络日志
