Description

采用生活污泥生产沼气与有机肥的方案
技术领域
利用全国居民生活区，军队，机关，学校的卫生间与灶间的排放及拣选后的生活垃圾做生产沼气原料，建沼气井生产沼气与天然气并网，以再生资源补充矿产资源，环保节能，沼气渣制作高效有机肥，改良贫瘠的土地，替代化肥，这是个巨大的再生资源，该项目的实施：减轻了污水处理厂的负担，减少了污泥的处理量，在源头上截住了污泥的流量。节约了大量的填埋污泥的土地，节省了大量的污泥处理费，增加了两个巨大的再生资源亮点，沼气与高效有机肥。解决了全国的污泥毒泥围城的环保尴尬困境，严禁并杜绝了压滤掩埋污染地下水导致二次污染的危险。
背景技术
据统计，截至2014年3月底，全国市、县累计建成污水处理厂3622座，污水处理能力每日约1.53亿立方米。到2015年，全国全年城镇污水处理厂湿污泥(含水率80％)产生量将达到3359万吨。多年来污水处理厂污泥污染环境事件不断的发生，为我们敲响警钟，引起我们高度关注，污泥的处置已经成为全国的污水处理厂最大的难题，很大程度上因为污泥处置费用没有直接的财政投入，一些地方就采取简单的深层填埋，导致了污染地下水的案件不断发生，更坏的情况是拿到了处理费却私下做了污泥交易，卖到了蔬菜种植大棚里做了深层底肥。污水处理厂处理过的污泥含水率高、易腐败、有恶臭，含有“致癌致畸致基因突变”的有机污染物，二噁英等。污泥中含有毒有害的杂质属于细微颗粒180目至240目，深层掩埋后，细微颗粒中含有大量病原菌、寄生虫(卵)，铜、锌、铬、汞等重金属以及多种有毒有害物，进入地下水系污染地下水。新鲜污泥中检测得到的病原体多达千种，其中危害较大的是寄生虫，对环境和人类以及动物健康构成危害。而污泥中富含的重金属带来的污染，会使土地不再适宜耕作，特别是庄稼和蔬菜的污染，更加严重的是，全国全年城镇污水处理厂湿污泥(含水率80％)产生量将达到3359万吨，如果还在继续深层填埋，那将会是，我们国家的土地与地下水，产生一个重大灾难。
发明内容
利用全国居民生活区，军队，机关，学校的卫生间与灶间的排放及拣选后的生活垃圾做生产沼气原料，建沼气井生产沼气与天然气并网，以再生资源补充矿产资源，环保节能，沼气渣制作高效有机肥，改良贫瘠的土地，替代化肥，经测算，每年能为国家生产上千万方沼气补充天然气，每年能为国家生产上亿吨高效有机肥替代化肥改良土地。这是个巨大的再生资源，该项目的实施，彻底消除污泥，毒泥围城的尴尬局面，变害为宝，形成一个良性的再生资源替代矿产资源的循环系统，该项目的实施：一，减轻了污水处理厂的负担，减少了污泥的处理量，在源头上截住了污泥的流量。二，节约了大量的污泥填埋土地，节省了大量的污泥处理费，三，增加了两个巨大的再生资源亮点，沼气与高效有机肥。四，解决了全国的污泥毒泥围城的尴尬困境，严禁并杜绝了压滤掩埋污染地下水导致二次污染危险。生产沼气与天然气并网，用再生资源替代补充矿产资源，生产高效有机肥替代化肥，改良贫瘠的土地，解决国家粮食产量和粮食安全问题，老百姓再也不吃化肥超标的粮食和蔬菜。
具体实施方案
科研团队经过多年调查研究，论证，试验，结论是该项目可行性强，在城市乡镇的低洼区僻静处，建多个大型的地下化粪池与沼气井，做好防爆安全措施及防雷措施，将机关，学校，军队，团体，居民小区，卫生间灶间的排放集中，经过管网输送进入各个区域的化粪池再由密封泵吸入沼气井。将经过拣选的生活垃圾投入沼气井，生产沼气与天然气并网，经过了发酵处理的沼渣是高效有机肥的最好的原料，采用密封泵将井里的沼渣吸入罐车，送去肥料厂与其他肥料拌合生产高效有机肥。生产沼气具体的设备设施，一、建封闭的大型化粪池数个，在该区域的低洼处，采用挖掘机正负零以下深挖十五米，呈圆形，钢混结构做好防渗处理，上收口处采用密封设置，并安置大型密封泵。二、在化粪池的周边设置沼气井数个，采用挖掘机正负零以下深挖十米，呈圆形，钢筋混凝土制作，做好防渗处理。具体的安装制作实施细则应按照西海湾科研团队的发明专利进行实施。三、该设施建成后，必须达到环保标准，不渗漏，不泄露，不跑味。做好三防，防火，防爆，防雷击。该项目的三防和三不，必须由政府机构的监督，检查，定期抽检，方能实施。四、沼气池生产的沼气与天然气的中端管道连接，加装流量表，沼气渣，出井时采用密封泵吸入密封的罐车。运送到肥料厂制作有机肥。五、机关，学校，军队，团体，居民小区的卫生间灶间的排放，是生产高效有机肥的最好的原料，不可与工业化工业排放的污水交融一起，工业污水里，有毒有害杂质重金属含量很高，不能生产高效有机肥，有毒有害杂质重金属含量很高的污水，应自行处理或另行管道进入污水处理厂处理。
