水治理作文篇1
亲爱的各位朋友们:
11月26日,我市突降大雾,能见度降低。气象专家预计,由于气象条件依然不利于空气中污染物扩散,雾霾天气或将继续加重,并将持续。此次雾霾天气主要是由于昼夜温差在10℃以上,较大的温差在我市市区形成了逆温层,持续逆温和弱风气象,水平和垂直方向上不利于污染物扩散,积累形成了雾霾天气。从气象条件上来说,冬季不利于污染物扩散的气象条件较多,每逢临近供暖期,必然出现大雾,今年冬天也不排除会再次出现雾霾天的可能性。为了防范雾霾在生活中带来的种种不便,提出以下建议。
一是合理安排好生产、交通和群众生活。雾霾天气市民应尽可能少出门,取消晨练,非要出门时最好戴上医用口罩防护,避免呼吸道受刺激导致疾病发生;外出归来,应立即清洗面部及裸露的肌肤。患有心血管疾病的人,尤其是年老体弱者,不宜在雾天出门,更不宜在雾天晨练,以免发生危险。
二是倡议采取建议性污染减排措施。公众自觉采取节能减排措施,尽量乘坐公共交通工具出行,减少小汽车上路行驶;停车时及时熄火,减少车辆原地怠速运行;施工工地自觉增加洒水次数,减少建筑工地扬尘。教育主管部门可以根据天气情况制定针对极端天气的安全防护预案,当遭遇沙尘天气时,叫停课间操、体育课等户外活动,可以将体育课安排在室内进行,或临时调课,不要让孩子成为吸尘器。
三是农业部门积极推广先进的耕作制度。积极推广免耕法,将作物残茬留于地表,在秋季整地期间,禁止城郊及周边县市农民大量焚烧秸秆,避免产生浓重的烟尘。
四是建立和完善雾霾天气的动态监测 预警系统。加强pm2.5监测网的建设,针对我国雾霾天气的特点,研究雾霾天气动态监测方法,利用卫星遥感、雷达和探空等手段对雾霾天气的形成、发展和扩散进行跟踪观测,形成一个实时的雾霾天气监测预警系统,并及时发布信息,以利于提前安排好生产、交通和群众生活、尽可能减少损失。
雾霾天气虽然造成空气质量严重下降,但只要注意防范,注意合理的安排,就可以减少雾霾给人们生产生活带来的影响。
水治理作文篇2
妈妈曾对我说过,老城区的鳄鱼湖水以前非常脏,不时会散发出臭气,那里的鱼不能吃。妈妈还说湖里的脏水是老城区的居民们排放没有经过处理的生活污水,当时的鳄鱼湖就象个天然的污水处理厂,污水排入鳄鱼湖后,有害物质就留在湖里,干净的水流向到河里。我想没有人愿意居住在这样一个天然的“污水厂”旁边。后来经过整改,现在湖水变得干净了,去年春节,爸爸妈妈还带我去湖里划船呢。河源市正在创建国家卫生城市,城市的污水处理是个很重要的地方。为此,学校组织我们小记者们专门到城南区的污水处理厂参观。现在,就让我们一起走进污水处理厂,看看它是怎样工作的吧。
走进污水处理厂,一股臭味扑鼻而来,原来是污水沟的污水发出来的臭气。这些污水都是工业、生活上的污水,可能和以前的鳄鱼湖水那样臭吧!污水沟有五米多深,这些污水要经过大、小格删、沉沙池过滤沉淀,将污水的泥土和垃圾初步处理。这是污水处理的第一关。
接着,污水经过除臭以后,就流入氧化沟。来到这里,污水变得“乖”了许多。站在上面已经闻不到臭气。污水经过氧化后流进二沉池,在二沉池的刷子通过旋转将污水的微沙物洗干净。那些微沙物可以用做养花的材料,或者做成泥饼,用来做人行道的泥转。
经过二沉池的水在流进“湿地公园”时,湿地公园的植物会大口大口的吃掉污水中的有毒物质。污水的杂质都消失的无影无踪了。处理后的水,从一个小瀑布流出来,这时的水变的清澈见底了!水流进了鱼池里,鱼儿在欢快的游着。到了这里,同学们欢呼着:“太棒了,太棒了,污水变清水了,真神奇!”
就是有了这样神奇的污水处理厂,才让我们有了一个美丽的鳄鱼湖,有了美丽的东江水。河源是一个山清水秀的城市,在外地的亲戚回来常会说河源的生活环境真是好,空气清新,水质清甜。听他们的评价,我觉得很自豪,觉得保护环境,保护家园是我们每一个河源人义不容辞的责任,希望全市人民都能“既要金山银山,更要绿水青山”。我要为保护我们的城市环境做出努力,平时养成节约用水的习惯,减少生活污水,保护东江水,保护万绿湖,保护绿色的河源!

recently, the weather is always foggy, and i want to go out to play the desire to always be ghost weather to stir. by reading the newspaper, i understand that this weather is haze, it is because the air suffered more serious pollution in a certain conditions under the formation. it seems that the air quality around us is really worrying wow.

水治理作文篇5
五水共治是指治污水、防洪水、排涝水、保供水、抓节水,这的确是五个要非常重视的的问题,可为什么会在江南水乡出现这个问题呢?原来,现在有好多工厂都把废水和赃物排放到河里,造成很多河流严重污染水质。
我在书上看到过江南水乡以前的美丽风景,山上的树木,满山的花,还有清澈见底的山涧,以前,在这种美景还在的时候,只要,伸手进去,就会摸到一串夏日时青蛙产下的卵……可是现在,各大化工企业都排出恶心的污水,我们都不敢伸手了:不治污水,污水泛滥,水不能喝了,会臭的。
原来,江南水乡一片片绿绿的水,蓝蓝的天。可现在,全是黑、灰这单调的颜色,讨厌极了。
“五水共治”确实很重要,如果不遵守“五水共治”里的几项规定,严重破坏了水中生物的家园与生活。
五水共治中最重要的就是抓节水了,你要想:人不节水,水被用光了,能喝的水都没了,做饭都没水了,喝污水,那你还不恶心?到没水的时候,你还不得渴死了?所以,节水很重要!节水这项工程还是需要大家共同努力的,水没了,那前面的四项都用不上了,人也要死了,那多不好!再说了,只有这一项是我们力所能及的,可以从自己做起的。
还有一条“治污水”这个也是靠我们一起合作完成的小部分,只要不让白色垃圾污染河流就可以了,可有些人却不会这样,老往河里扔垃圾。
哎,“五水共治”太难了,但是,只要尽力而为,都没关系,我相信,只要大家都努力了,就可以把这“五水”治好!地球母亲呵护着我们的成长,不能让他毁在我们的手上,我们应该让他更好!

水治理作文篇7
以前总是听见高年级的哥哥姐姐们在说“参观污水处理厂“后的想法,所以参观污水处理厂就成为我长久以来的愿望。
今天是一个万里无云的好天气,也是实现我梦想的一天。下午4:30我们向污水处理厂出发了,我们步行来到了梦寐以求的目的地。以“迅雷不及掩耳之势“冲进了参观污水处理厂的大门,差点把门给挤破了。
开始参观了,第一个坠入我眼帘的是由许多弯钩组成的细隔层,弯钩不停地上下滚动,以至水流中的塑料袋等杂物被钩去。第二个参观的是停留沉沙池,只见池上漂浮着无数个颗粒状的物体,在与停留沉沙池隔着一层隔离网的下面冒出了一股股被除去脏物但仍然浑浊的水流。此时此刻我们激动极了,不由自主地奔向另一个目的地。
这是一个一望无际的大型水池,远远看去只是一片浑浊污水。我走进一瞧,才知道原来是许多的泥沙在水中起舞。继续前进,一条如瀑布般的急流在一瞬间就与下面的水池容为了一体。再向前走,一路上我在想:接下来的景象是什么?它壮观吗?想着想着就到了,“叮咚叮咚“这是什么声音,我环顾四周发现了许多的清泉,那水清澈透明,如同一面镜子。
浑浊不堪的生活污水经过参观污水处理厂的处理竟能变成清水,这真是太神奇了!
