Sludge liquor is recirculated in the secondary system . 污泥水回流到二級處理系統(tǒng)。
If the spray water is recirculated until equilibrium conditions exist . 如果噴淋水不斷循環(huán)直到穩(wěn)定狀態(tài)。
Sludge liquor is recirculated in the secondary system to assure its purity before discharge . 該泥水回流到二級處理系統(tǒng),以保證排放前的澄清度。
Environmental protection : no contact between water and the products , and the water can be recirculated 高度環(huán)保:物料從熔融態(tài)到固化過程,和冷卻水完全不接觸,避免相互污染,并且冷卻水可循環(huán)使用。
The area along the edge of the pool in which water overflows during a race and is recirculated through the filtration system 位于游泳池邊緣的地方,在比賽時允許水越過去。并且通過過濾系統(tǒng)再流回來。
In this combustion mode the mixture , composing of the fuel , air and the recirculated exhaust gases ( egr ) , is compressed , auto - ignited , combusted 成功的實現(xiàn)了乙醇燃料hcci燃燒的測控平臺。研究結(jié)果表明:進氣溫度、過量空氣系數(shù)和egr率對乙醇燃料的hcci燃燒有重要影響。
Abstract : carbon dioxide was introduced into the wheat bulk stored in a brick silo through a duct system and was recirculated for even distribution till co2 concentration to 70 96 in wheat bulk 文摘:二氧化碳被導(dǎo)入一管道系統(tǒng)并使其在磚筒倉的糧堆內(nèi)逐漸均勻分布,直到其在糧堆中的濃度達70以上。
Most of the ac systems in the fehd public markets are equipped with disinfection units and filters to disinfect and remove particulate matters , dust and odour from the recirculated air (二)食環(huán)署轄下公眾街市的空調(diào)系統(tǒng)大都設(shè)有空氣凈化系統(tǒng)和過濾器,為循環(huán)的空氣消毒、清除懸浮粒子、塵埃和臭味。
Rate of leachate effluent recovery through reverse - osmosis membrane is about 75 % ~ 80 % , withholding almost all kinds of pollutions in leachate , the concentrated leachate which produces in the treatment is recirculated to the landfill , it is helpful to degradation of landfill 通過反滲透膜的垃圾滲濾液出水回收率占其體積的75 % ~ 80 % ,截留了垃圾滲濾液中幾乎全部的污染物質(zhì),產(chǎn)生的濃縮液回灌到垃圾填埋層,有利于垃圾的降解。
Abstract : study is made of recovery of organic reagents during the preparation of ultrafine powder by metal alcoxides hydrolysis . the phase diagrams of isopropanol - benzene system and isopropanol - benzene - water system have been plotted , based on which , isopropanol and benzene can be recovered and recirculated by distillation - rectification process . the recovery and reused rate of alcohol and benzene are above 75 % . so both the environmental pollution and cost of ultrfine powder are reduced 文摘:對醇鹽水解法制備超細粉末過程中有機試劑的回收進行了研究,繪制了異丙醇-苯的二元相圖和異丙醇-苯-水的三元相圖,在此基礎(chǔ)上采用蒸餾-精餾的方法對制備體系中的異丙醇和苯進行回收,將有機試劑循環(huán)使用,使醇和苯的回收利用率達75 %以上,因而減少了環(huán)境污染,并降低了粉末成本。
