Description
本发明涉及家庭污水处理与回收领域，尤其涉及一种家用水处理控制方法及其装置。
目前，我国城市居民家庭日常生活中，洗衣、洗菜、洗浴等生活用水均采用自来水，使用一次就倒掉了，而洗衣以及厕所冲洗坐便器使用了大量的清水，消耗大量水资源，又排放大量污水，造成水资源的浪费。实际上除坐便器排放的污水以外，洗衣、洗菜、洗浴等生活废水均有回收利用的价值；回收的污水经处理后可以作为冲洗坐便器用水、洗衣以及清洗地面用水等等。因此，如何对家庭污水进行处理，并使之达到相应的标准的研究备受关注。
家庭生活用水除冲洗坐便以外主要集中在洗衣、洗碗、洗菜以及洗漱上，现有技术中对洗衣用水的处理再利用大多是通过节水洗衣机或者絮凝洗衣机中水处理装置进行的，处理后的水仅用作洗衣机的漂洗用水，洗碗、洗菜以及洗漱用水往往是集中存放再进行过滤后用作冲洗马桶用水，可见现有的家用水处理是针对不同的污水单独设置处理装置，对于家庭生活中的不同类型的污水，还不能实现无差异化重复利用，使得家用水处理成本高、水处理装置的使用与检修都需要逐个进行，给用户造成了不便，并且处理后的水不能按照用户的需要随意取用。
为解决上述问题，技术人员着手研究针对家庭生活中的不同类型的污水统一进行处理再利用的装置，申请号为CN201020588377.0的中国专利公开了一种生活用水处理装置，用于小水量生活用水处理，主要由除砂器、臭氧反应装置、臭氧发生器、加压泵、絮凝加药箱、多介质过滤器、活性炭吸附器、中间水罐、精密过滤器、反渗透装置、储水罐和变频供水泵组成，处理工艺流程中包括混合、絮凝、沉淀或澄清、过滤及消毒，使得处理后的出水达到并高于生活饮用水水质标准。但是，用户对于经过处理后的家用水通常不会将其用作饮用水，而是满足一些要求不高的用途即可如擦地和冲洗坐便等。
所以上述的生活用水处理装置就存在结构复杂、占地面积大、造价高、维修不便等问题。并且如果将家庭生活中的污水汇总到一起统一进行处理，由于污水的类型不同，无法像处理某一种污水时如处理洗衣水时可以根据洗涤水进水量或者洗涤衣物的重量或者材质来确定絮凝剂的投放量与絮凝处理次数，但是上述的生活用水处理装置无法确定絮凝剂的投放量与絮凝处理次数，所以难以达到预期的处理效果，并且如果为达到水处理效果，增加絮凝剂的投放量与絮凝处理次数，将会造成很大浪费。
有鉴于此特提出本发明。

本发明将家庭生活中不同类型的污水汇总到一起进行处理，由于污水的类型不同，对其进行絮凝处理时，絮凝剂的投放量存在差异，为便于统一处理，采用多次絮凝处理的方法，每次进行絮凝处理前检测水的浊度和/或电荷量，逐次确定絮凝剂的投放量，实现了对絮凝剂投放量的精确控制，既达到了水处理效果，又避免了投放絮凝剂过量造成浪费。
本发明通过采用多次投放絮凝剂处理水，并计絮凝处理次数，直到达到设定的条件结束水处理的方法，设定两个优先级条件，第一优先级条件为絮凝处理后水质达到预设定的水质标准，如果水质达标则结束水处理，如果未达标再用第二优先级条件进行判断，直至达到第二优先级条件，则停止水处理并报警，并且在多次投放絮凝剂处理水中，每次絮凝剂的投放量根据投放絮凝剂前检测的水质确定，采用上述方法就可以根据对处理后的水质标准的不同要求以及待处理的污水的脏污程度，进行合理次数的絮凝处理，当待处理的污水过脏不具备处理再利用的价值时，将会停止水处理并报警，这样避免了由于絮凝处理次数过多以及絮凝剂投放过多而造成的水处理效率低，成本高的问题。

下面结合附图对本发明的具体实施方式作进一步详细的描述。
图1为本发明实施例提供的家用水处理步骤流程图；
图2为本发明实施例提供的家用水处理装置结构示意图；
图3为本发明实施例提供的家用水处理装置结构示意图；
图中：外壳1、反应桶2、出水装置3、排水装置4、进水装置5、投放装置6、控制装置7、水位检测装置8、浊度检测装置9、电荷检测装置10、搅拌装置11、过滤装置12、水泵13、进水接插装置14、操作显示区15、出水龙头16、其他家电17、储水箱18。
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对实施例中的技术方案进行清楚、完整地描述，以下实施例用于说明本发明，但不用来限制本发明的范围。
现有技术中往往是针对某一种类型的污水，根据该类污水的脏污来源并且参考待处理的污水量等因素，确定絮凝剂的投放量，进行一次或者固定次数的絮凝处理。但是当需要对混合污水进行处理时，由于污水的类型不同，采用上述方法无法通过污水的脏污来源和污水量等因素确定絮凝剂的投放量，对其进行絮凝处理时，可能会出现絮凝剂的投放过量的情况，不但对水质造成影响，而且也导致絮凝剂浪费、水处理成本大的问题。
针对以上问题，本发明所述的方法对家庭生活中汇总的不同类型的污水统一进行处理，采用进行多次絮凝处理的方法，每次进行絮凝处理前检测水的浊度或电荷量，或者每次进行絮凝处理前同时检测水的浊度和电荷量，根据检测的值确定每次絮凝处理的絮凝剂的投放量，使得现有技术中一次投放絮凝剂的投放量存在的较大误差，被上述多次絮凝处理过程中依据水的检测结果确定每次投放量的方法所修正，既保证了处理后的水质达到要求的同时，又实现了对絮凝剂投放量的精确控制。
现实生活中，用户对于经过处理后的水质要求并不完全相同，有些用户对于处理后的水质要求较高，大部分用户对于处理后的水通常不会将其用作饮用水，而是满足一些水质要求不高的用途即可，如擦地和冲洗坐便等。要使脏污程度不同的污水经处理后达到某一水质标准，直接影响到水处理效率和处理成本，其差异较大，具体来说，第一种情况，当待处理的污水脏污程度较小时，仅需要进行一次或者少数次絮凝处理、投放少量絮凝剂就可以达到水质要求，此时水处理效率较高、处理成本较低；第二种情况，当待处理的污水脏污程度较高时，需要进行多次絮凝处理、投放大量絮凝剂才可以达到水质要求，此时水处理效率较低和处理成本较高。对于用户来说，将处理水用于水质要求不高的如擦地和冲洗坐便时，第二种情况水处理的效率低且成本高，并不符合用户对于家用水处理经济实惠的要求，此时对于用户来说，待处理的污水过脏已经不具备处理再利用的价值，但是用户无法判断家庭生活汇总的污水是否具备处理再利用的价值。
为解决上述问题，本发明通过采用多次投放絮凝剂处理水，并计絮凝处理次数，直到达到设定的条件结束水处理的方法，设定两个优先级条件，第一优先级条件为絮凝处理后水质达到预设定的水质标准，如果水质达标则结束水处理，如果未达标再用第二优先级条件进行判断，直至达到第二优先级条件，则停止水处理并报警，并且在多次投放
絮凝剂处理水中，每次絮凝剂的投放量根据投放絮凝剂前检测的水质确定，采用上述方法就可以根据对处理后的水质标准的不同要求以及待处理的污水的脏污程度，进行合理次数的絮凝处理，当待处理的污水过脏不具备处理再利用的价值时，将会停止水处理并报警，这样避免了由于絮凝处理次数过多以及絮凝剂投放过多而造成的水处理效率低，成本高的问题。
其中，设定条件包括：第一优先级条件为絮凝处理后水质达到预设定的水质标准，第二优先级条件为絮凝处理次数达到预设定次数。采用本发明的方法对家用水进行处理时，可根据预期的处理后的水质要求，设定与该水质对应的水的浊度值M或者水中电荷量值Q作为水处理完成的标准，根据用户期望的处理效率与处理成本预设定絮凝处理的次数N，开始处理后，计絮凝处理的次数X，每次絮凝处理后判断是否达到了预设定的絮凝处理的次数N。
如果X＝N，即絮凝处理的次数达到了预设定的次数，则停止水处理并报警，此时说明待处理的污水脏污程度较高，需要进多次絮凝处理并投放大量絮凝剂才可以达到水质要求，此时水处理效率低于用户期望，处理成本高于用户期望，用户收到报警提示后，仍可选择继续进行水处理，如果认为不具备处理再利用的价值时可放弃水处理。
如果X<N，即絮凝处理的次数未达到预设定的次数，则每次絮凝处理进行水处理后，检测水的浊度或电荷量，或者检测水的浊度和电荷量，若低于设定的浊度值或电荷量值，或者既低于浊度值也低于电荷量值，则水处理结束，处理后的水达到预期的水质要求；否则继续絮凝处理，直至X＝N，即絮凝处理的次数达到了预设定的次数。
需要说明的是，一次絮凝处理包括投放絮凝剂、进行搅拌、搅拌后静置。其中在本次絮凝处理开始前，根据上一次絮凝处理后检测水的浊度或电荷量，或者同时检测水的浊度和电荷量，根据检测的值确定本次絮凝处理的絮凝剂的投放量。
实施例一
如图1所示，在本实施例中，家用水处理控制方法的具体步骤如下：
步骤S101，将污水通入水处理装置并检测水位；
步骤S102，达到预设水位值时，停止通入污水并检测水的浊度；
其中，为提高水处理效率，通入的污水的水量达到预设定的水量后再进行絮凝处理，预设定的水量可以由用户直接设定，通入的污水的水量经水处理装置中设置的水位检测装置检测得出，预设定的水量与水处理装置中絮凝处理的容器大小有关。并检测水的浊
度记为M1。
步骤S103，根据检测的水的浊度确定初次絮凝处理絮凝剂的投放量，投放絮凝剂；
絮凝剂初次投放量与浊度值M1有关，根据浊度值M1选择对应的絮凝剂投放量，一般的，根据M1所在的区间确定对应的絮凝剂投放量。
步骤S104，进行初次絮凝处理，搅拌水处理装置中的水t1时间，再静置t2时间；
絮凝剂投放后，对水进行搅拌，使得絮凝剂快速溶解并均匀分布，生成絮凝物，搅拌预设定的t1时间，停止搅拌后静置t2时间，进一步进行絮凝反应。
步骤S105，静置后检测的水的浊度值，若低于设定的浊度值，执行步骤S109；否则执行步骤S106；
步骤S106，判断絮凝处理次数是否达到设定次数，达到设定次数，执行步骤S108；否则执行步骤S107；
步骤S107，未达到设定次数，则根据检测的水的浊度确定再次投放絮凝剂的投放量，投放絮凝剂，搅拌水处理装置中的水t1时间，再静置t2时间，再次执行步骤S105；
步骤S108，停止水处理并报警；
步骤S109，水质达标，水处理结束。
经过搅拌与静置后，检测絮凝后水的浊度值记为M2，并计絮凝处理次数为X1，当测得处理后的浊度值M2小于设定值M时，则水处理水质达到标准，水处理结束。将处理后的水经过滤排出用做其他用途；当测得处理后的浊度值M2大于等于设定值M时，此时水处理水质未达到标准，是否继续絮凝处理需要判断絮凝处理次数是否达到设定值N。
如果X1＝N，即絮凝处理的次数达到了预设定的次数，则停止水处理并报警，此时说明待处理的污水脏污程度较高，不具备处理再利用的价值时可放弃水处理。
如果X1<N，即絮凝处理的次数未达到预设定的次数，则可继续絮凝处理，再次执行步骤S105，再次执行絮凝处理计次数为X2，直至计数等于N。
上述步骤S103至步骤S107为一次絮凝处理，水处理絮凝过程中按上述步骤S103至步骤S107处理重复执行，每处理一次水处理的絮凝处理次数累加一次，至絮凝处理次数达到X＝N时，絮凝处理过程结束；其中，絮凝处理次数N，根据用户期望的处理效率与处理成本确定。
实施例二
在上述实施例的基础上，本实施例所述的方法是将上述检测絮凝后水的浊度值替换为检测絮凝后水的电荷量值，或者既检测絮凝后水的浊度值同时也检测检测絮凝后水的电荷量值，其中浊度与电荷量通过水处理装置中设置的浊度检测装置和电荷检测装置检测得出。
在絮凝反应过程中，这些脏污粒子会絮凝剂结合在一起形成大的絮凝物。在搅拌的作用下，当絮凝物中包裹较多气体时的其重力小于其所受的浮力，此时絮凝物上升，在絮凝反应桶中水与絮凝物分离的效果。通过大量实验发现，絮凝剂超量投放与絮凝剂欠量投放都会造成水的浊度升高，而当投放量差值超过一定范围时浊度会急剧上升，此时再通过检测絮凝后水的浊度值确定絮凝剂的投放量则会存在较大误差，将影响再一次的絮凝效果或者絮凝剂投放过量造成浪费。
由于污水中的主要脏污粒子主要有以下成分，泥沙、粘土、不溶性物质以及一些可溶性的盐类等。而这些杂质绝大部分都是带负电荷的粒子，而絮凝剂水解后形成带正电荷的粒子，因此，絮凝剂所带的正电荷能中和水中脏污粒子所带的负电荷，当絮凝剂添加最适量时，水中剩余电荷数为0。所以为解决上述问题，可以在检测水的浊度值的基础上进行水中电荷量的检测，当检测到水中的正电荷过剩时，说明上一次絮凝剂过量投放，当检测到水中负电荷过剩时，说明上一次絮凝剂欠量投放。以该检测结果确定絮凝剂的投放量，可根据检测值范围所对应的适宜的絮凝剂量投放，减少絮凝剂投放量的误差。
实施例三
如图2和3所示，在上述实施方式的基础上，本发明所述的家用水处理装置包括外壳1、设于外壳1内的对水进行处理的反应桶2，反应桶2内设有水位检测装置8、浊度检测装置9、电荷检测装置10以及对其内水进行搅拌的搅拌装置11，家用水处理装置还包括分别与反应桶2连接的：用于出经过处理后达标水的出水装置3、排出絮凝物以及经过处理后未达标水的排水装置4、用于把待处理污水通入到反应桶2中的进水装置5、用于投放絮凝剂的投放装置6以及控制装置7，控制装置7与水位检测装置8、浊度检测装置9、电荷检测装置10、搅拌装置11以及投放装置6电连接。
家庭生活中的各类型污水可以统一收集并存储在储水箱18中，进水装置5通过水泵13与储存待处理污水的储水箱18连通。
本发明的装置开始水处理程序后，开启水泵13，储水箱18中待处理的污水流入反应桶2中，当水位检测装置8检测到流入的水达到设定水位，水泵13关闭。浊度检测装置9检测反应桶2中水的浊度值，絮凝剂投放装置6向反应桶2中投放根据该检测值
对应量的絮凝剂，搅拌装置11搅拌反应桶2中的水一定时间，搅拌后再静置一定时间，使水中的污物变为絮凝物漂浮至絮凝处理后的水上表面。浊度检测装置9、电荷检测装置10对水进行检测，根据检测结构判断水质是否达标，如达标通过出水装置排出再利用，如不达标根据本发明所述的方法判断是否进行再一次絮凝处理或者停止净水、控制装置7进行报警。
出水装置3包括将絮凝处理后的水进行过滤的过滤装置12，过滤装置12可拆卸的设于外壳1内。过滤装置12与反应桶2相连通，将反应桶2内絮凝处理后的水进行过滤，再由出水装置3排出再次使用。通过加设过滤装置，避免了絮凝物随处理后的水一起流出的情况发生，也提高了水处理的效果。
排水装置4可通过排污阀(未图示)与反应通2连通，将絮凝物、沉淀的泥沙以及经过处理后未达标水和对反应桶进行清洗的水排出。
实施例四
如图2和3所示，在上述实施方式的基础上，本发明所述的家用水处理装置的进水装置5还包括可与其他家电17的排水口配合连接的进水接插装置14，控制装置7还包括可以与其它家电17配合连接的通讯部分。本发明所述的家用水处理装置既可以与储水箱18连接对不同类型混合的污水进行处理，也可以与其他家电如洗衣机直接连接，进行针对一种类型的污水进行处理。当与其他提供待处理水的家电连接时，控制设置7可设为联机模式，即受控于提供待处理水的家电完成水处理。
需要说明的是，上述实施例中的实施方案可以进一步组合或者替换，且实施例仅仅是对本发明的优选实施例进行描述，并非对本发明的构思和范围进行限定，在不脱离本发明设计思想的前提下，本领域中专业技术人员对本发明的技术方案作出的各种变化和改进，均属于本发明的保护范围。
