The ZOOMLION KSD25 Dry-Wet Horizontally directional Drill is the first drill which drills through hard rock without a bentonite and mud pump. Its pneumatic percussive technology has not only solved the problem of mud pollution, but also has increased its efficiency 40% higher than a normal drill. Additionally, its cost is also much lower, and therefore, it has been considered as a most efficient solution for complicated stratum (including pebble and gravel, backfill and rock).

中联KSD25干湿两用水平定向钻孔机是我国第一台不使用膨润土和泥浆马达就能在硬岩中钻进并导向的钻机，其国际领先的气动冲击钻机技术不但不存在泥浆污染的问题，而且效率比普通钻机提高40％以上，成本也要低廉得多，被公认为目前对付复杂地层（包括卵砾石、回填土和岩石地层）最为有效的方法。2 s# C J， k5 _% C

Different fillers for wetlands are chosen by comparison and then matched, the following filler matching is achieved aiming at different influent: for wastewater with low nitrogen concentration and medium or high organic matter concentration, better removal efficiency is attained by combined fillers of coal cinder + pebble stone + gravel; for wastewater with high nitrogen concentration and low organic matter concentration, the optimum combination is fly ash brick crumbs + gravel.
