第535章 水利工程(2 / 2)

“啊???”学生们忽然来了精神。

“将污水排到野外,让爬行动物喝吗?长久下去他们就被毒死了。”有学生说。

“那不只毒死爬行动物吧?其他动物也会被毒死,搞不好误食喝了有毒废水的动物,连带我们自己都要嗝屁!”

“不不不,我有个疑问,爬行动物那么傻吗?闻到味道怪异的水还回去喝?”

“在立刻渴死和慢性毒死之间你选什么?”

“。。。”

闻人楚笑眯眯的看着重新活跃起来的课堂氛围,任由学生们自由讨论着。

“你说将废水引入挖掘完的护城河里?那兽人的居住环境不是都被废水包围了?”万兽城政府大楼会议室里,白尾蹙眉不解的看着闻人楚。

“我说的废水并不是工业废水,而是农业废水。咱们的种植业到目前为止还没有出现利用化学药剂促进生长的情况,所以一段时间的物理沉淀是可以再利用的。沉积池底部沉淀物粘稠,若是有爬行物进入可以进一步阻碍它的行动。”闻人楚解释道。

“农业废水经过处理之后是不是可以再利用?野外动物喝了会死吗?”莉娜问道。

“可以循环利用,动物喝了不会死,在经过暴晒之后细菌都会减少。”

金闻言点头, “这样护城河战时可以进行防御,闲时可以浇灌农田,一举两得。”

“可是每个城市的种植规模不同,有的城市偏向制造业而农田稀少,他们没有那么多农业废水怎么办?”

“对啊,我们那除了人多,什么都不多!”

“那就用另一种水利工事。”闻人楚笑道。

“快讲讲!”

“地势有高低的地方可以在高处建立大坝和蓄水池,一旦有爬行动物上山就开闸放水。不过我说的这点只是一个设想,还需要因地制宜。我是比较建议在现在这个阶段,大家将房子盖的紧密一点比较好,就算什么都建不了,我们还可以拉电网进行恐吓防御。”

“。。。嗐,还不是之前那什么大航海时代到处都是水,空气到处黏黏乎乎的,人跟人之间都懒得见面,这才将房屋建的稀疏了,以前咱们扎堆住着的。”有兽人叹了口气,现在又要重建房屋,想想都头大。

兽元355年,万兽国第一批水利工程师走出校门,他们被分配到各个省市,帮助当地进行符合当地地理环境的水利建设。

而在这一年,经过全国兽人日以继夜地辛勤劳动,大到城市,小到村镇都拥有了属于他们自己的‘护城河’。

万兽国的城卫和猎人们在此期间不知道走了多少路,砸了多少蛋,才将国内不断增长的爬行动物数量抑制住了,至此,万兽国与爬行动物之间终于找到微妙的平衡。
