Sweeps should be incorporated into the mud system as all dumped and surplus mud will have to be treated through the water clarification system 清掃液應同其他多余和丟棄的鉆井液一樣,必須通過澄清池加以處理,再匯入鉆井液系統(tǒng)。
It has been shown that this updated sampling and measurement method , which can measure the content of tar and dust individually , appears much more precise and credible , particularly aiming at the characteristic of heavy tar and dust content in biomass gas . this clarification system that adopts two - level shell and tube condensers and one tar removal filter , has the advantages of high removal efficiency ( 97 % ~ 98 % ) and low operating cost . besides , it has been made more environmentally friendly considering that wastewater from condensers has measured up to related effluent state standards after being disposed in tar clarifier - tank 多次試驗表明:針對生物質氣浙江大學碩士學位論文含焦油灰塵量大的特點,改進的生物質焦油取樣測量法可實現(xiàn)焦油和灰塵的分離,有較高準確性和可靠性;采用二級管殼式冷凝器與一級干式過濾器結合的燃氣冷凝凈化系統(tǒng)不但凈化效率高( 97 98 ) 、運行費用低,而且含焦油廢水二經(jīng)過澄清池澄清處理后可達到國家相關污水排放標準,避兔了濕式凈化系統(tǒng)的水污染;兼顧凈化效果、經(jīng)濟性和減少污染考慮,采用以半焦為吸附材料的于式凈化系統(tǒng)可以達到炊用燃氣對焦油含量的要求。
