问题 问答题


某住宅小区建设工程占地15.8万m2,建筑面积为260637m2。其中住宅建筑面积239756m2,配套设施建设15000m2。规划设计居住人口2140户,5992人;机动车停车位1046个,其中地上246个,800个位子。配套公建主要包括设备用房、超市、一所三班的幼儿园、车库。
该项目为一个大型村庄的整体搬迁改造工程(以下简称“开发小区”)的三期工程。该村庄改造共计四期,改造工程采取边拆迁边改造的方法。项目用地南侧为拟拆迁的某村居民住宅,东侧为一煤炭加工储运厂,西侧隔一条宽40m的城市主干道为一所中学,北侧为一高级写字楼,周围100m范围内建筑物最高为40m。项目所在地周围水、电设施齐全,属于开发区污水处理厂汇水范围,但项目周边尚无市政污水管网。开发区建有集中供热锅炉,但是项目周边市政供热管网尚未接入。拟建项目所在的开发小区以前建有供热容量为50t/h的燃煤锅炉,本供热锅炉原计划为项目邻近的小区提供热源,但是目前邻近小区供热方案发生了变化,未使用该锅炉。

水环境影响预测应按照什么思路进行

答案

参考答案:

解析:该项目虽然位于开发区污水处理厂范围内,但是开发区市政污水管线并未接入该开发小区周边,该项目水环境影响预测部分需按该工程自建污水处理设施考虑进行预测分析,并需根据工程用排水量,确定污水处理设施的规模、工艺。[考点分析] 房地产项目水环境影响预测分以下几种:①无城市污水处理厂和市政条件支持,水环境影响预测需估算污水排放量,明确污水水质类型,提出水质达标的建议(如自建污水处理站)。②属于城市污水处理厂的汇水范围,但市政条件不支持,水环境影响预测需估算污水排放量,明确水质类型,提出污水排放去向。若市政条件完善,不需自建污水处理设施,若市政条件不完善,则按不被城市污水处理厂接纳考虑。③属于城市污水处理厂汇水范围,市政条件支持,则水环境影响预测需估算水量,并分析市政接纳的可行性。该题属于第二种情况。

At the beginning of the twentieth century, North American society held, as an ideal, the Nuclear Family. This presumably perfect residential, social, and economic unit consisted of an adult male, an adult female and their minor children. This structure was thought to be stable and long lasting.
However, a few decades later, the structure of that ideal family was being altered radically even while it was being touted as the structure to be aimed for. Popular magazines bemoaned the loss of the Nuclear Family and its replacement with inferior forms.
There are a number of factors that are acting in concert to apply pressure on the Nuclear Family and generate a variety of new structures. Some of these are:
The definition of marriage has changed somewhat in that few people now consider it to last "until death do us part". The concept of monogamy (the marriage of one man and one woman) has been modified to a form now referred to as serial monogamy (the marriage of one man and one woman at a time). This reflects the increasing equality of women and men in terms of economic advantage and the recognition that many women no longer depend on men for their survival. Women are acquiring independence and have become empowered to make their own choices. With this independence, the need to form a relationship with a man becomes less important. This change embodies the concept that the marriage is temporary and can be terminated by either partner at any time. Associated with this, of course, is the relaxation of the divorce laws and the significant reduction of the shame that had one time been attached to divorce.
The economy of North America has resulted in a two-tier system of a few rich who control most of the resources and a large portion of the population who control almost none of the resources. Because of this, many couples are forced to have both partners with full-time jobs outside the home. There are unintended byproducts of the need for a double income. The most important of these is the replacement of a mother-oriented socialization of children to a "stranger-oriented" socialization system reflected in the growth of the childcare industry. Also, either partner is financially able to end the marriage without significant hardship.
The combination of these changes will in the coming decades have a profound effect on the structure of the family of North America. As a result, the family will be a fluid, constantly changing structure with variable household arrangements as the norm.
