Shandong of report from our correspondent saves first mud firedamp to generate electricity generation set of firedamp of mud of sewage treatment plant of island of wheat of project —— Qingdao succeeded a few days ago and the net generates electricity, took the lead in realizing mud to generate electricity in saving job of person of the same trade completely resource changes the breakthrough that use, realize trash resource to be used integratedly, managing many energy resources.
Since wheat island sewage treatment plant moved last year in July oneself, arise to achieve 600 stere via quantity of mud of centrifugal dehydrate digestive everyday, day all outside carry dehydrate dry mud can amount to 45 stere. In mud digestive process, can produce firedamp to achieve 10 thousand ~1.5 everyday 10 thousand stere, have development to use foreground. To make full use of mud digests the firedamp of generation, wheat island sewage treatment plant is using two oil gas generation set of firedamp of 4 500 kilowatt increased on the foundation of boiler of amphibious hot water. Bad news of only station of generation set of this kind of firedamp enrages 200 stere / hour, can generate electricity 400 kilowatt. Anticipate according to the design, real electric power uses up the basis inside the factory reach firedamp to produce tolerance, 4 firedamp generation set can hold 2~3 stage unit move, according to run stability of set of two aircrew only station to output 400 kilowatt wattmeter to calculate, the electric power of 100 kilowatt uses up itself of purify generation set, run two aircrew to be able to give the electric power that 700 kilowatt hour provide inside the factory output, everyday but managing town report sixteen thousand eight hundred kilowatt hour, cost saving can amount to 12 thousand yuan; Run 3 aircrew to be able to give the electric power that 1100 kilowatt hour provide inside the factory output, everyday but managing town report twenty-six thousand four hundred kilowatt hour, cost saving can achieve 19 thousand yuan. Current, day of wheat island sewage treatment plant all bad news report amounts to 35 thousand kilowatt hour, of firedamp generation set move, day all managing power consumption can amount to 48~75.4 % , will big earth reduces electric energy of market of sewage treatment plant to use up, reduce moving cost, raise economic benefits.
The pacing at the beginning of classics calculates, the mud bulk after digesting can reduce 30 % . Of this project carry out, in implementation the source changes trash endowment to be used integratedly while, produced considerable economic benefits and environmental beneficial result, reduced solid trash discharge capacity greatly.
