雨水和污水都属于城市排水工程。雨污分流是指将雨水和城市污水分开收集,分开排放。现在的城市建设中基本都要求雨污分流,通常采用分流井进行分流,而传统的分流井包括堰式、槽式、槽堰式、拍门等,传统分流井构造简单,建造成本低,但是存在以下缺点:①截污管容易淤积;②合流污水直接溢流至自然水体中,污染河道; ③存在污水及自然水体倒灌的情形(拍门易被漂浮物卡住);④固定堰影响行洪; ⑤截流管流量无法控制,影响污水厂正常运行。Both rainwater and sewage belong to urban drainage projects. Rainwater and sewage diversion refers to the collection and discharge of rainwater and urban sewage separately. In current urban construction, rainwater and sewage diversion is basically required, and diversion wells are usually used for diversion. Traditional diversion wells include weir type, trough type, trough weir type, flap gate, etc. Traditional diversion wells are simple in structure and low in construction cost, but have the following disadvantages: ① The interception pipe is prone to siltation; ② The combined sewage directly overflows into the natural water body, polluting the river; ③ There is a situation of sewage and natural water backflow (the flap gate is easily stuck by floating objects); ④ The fixed weir affects the flood discharge; ⑤ The flow of the interception pipe cannot be controlled, affecting the normal operation of the sewage treatment plant.

本发明还采用了另一个技术方案:The present invention also adopts another technical solution:

智能分流方法,使用如上述的分流井,包括以下模式:The intelligent diversion method, using the diversion well as described above, includes the following modes:

晴天模式,闸门处于开启状态,堰门处于关闭状态,截流管的闸门的开度使截流管的流量不大于截流管设定的最大流量,旱季混接污水通过截流管进入市政污水管网;In sunny day mode, the gate is open, the weir gate is closed, and the gate opening of the intercepting pipe makes the flow of the intercepting pipe no greater than the maximum flow set for the intercepting pipe. In dry season, mixed sewage enters the municipal sewage network through the intercepting pipe.

降雨模式,当上游井内液位小于降雨初期水位时,闸门处于开启状态,堰门处于关闭状态,截流管的闸门的开度使截流管的流量不大于截流管设定的最大流量,初期雨水和旱季混接污水通过截流管进入市政污水管网;In rainfall mode, when the liquid level in the upstream well is lower than the initial rainfall water level, the gate is open and the weir gate is closed. The gate opening of the intercepting pipe makes the flow rate of the intercepting pipe no greater than the maximum flow rate set for the intercepting pipe. The initial rainwater and dry season mixed sewage enter the municipal sewage network through the intercepting pipe.

降雨模式,当上游井内液位不小于降雨初期水位,且井内的COD浓度不小于COD设定值时,闸门处于开启状态,堰门处于关闭状态,截流管的闸门的开度使截流管的流量不大于截流管设定的最大流量,初期雨水和旱季混接污水通过截流管进入市政污水管网;In rainfall mode, when the liquid level in the upstream well is not less than the initial rainfall water level, and the COD concentration in the well is not less than the COD set value, the gate is in the open state, the weir gate is in the closed state, and the gate opening of the intercepting pipe makes the flow of the intercepting pipe not greater than the maximum flow set for the intercepting pipe. The initial rainwater and dry season mixed sewage enter the municipal sewage network through the intercepting pipe;

降雨模式,当上游井内液位不小于降雨初期水位,且井内的COD浓度小于COD设定值时,截流管的闸门关闭,堰门可调至半开,中后期雨水通过堰门溢流排入自然水体;In rainfall mode, when the liquid level in the upstream well is not less than the initial rainfall level and the COD concentration in the well is less than the COD set value, the gate of the intercepting pipe is closed and the weir gate can be adjusted to half-open. The mid- and late-stage rainwater overflows through the weir gate and is discharged into the natural water body.

降雨模式,当上游井内液位达到行洪水位时,截流管的闸门关闭,堰门完全沉入凹槽内,堰门全开,完全行洪,防止上游积水;In rainfall mode, when the liquid level in the upstream well reaches the flood discharge level, the gate of the interceptor pipe is closed, the weir gate is completely sunk into the groove, and the weir gate is fully opened to discharge the flood completely and prevent water accumulation upstream;

雨停模式,当上游井内液位小于雨停液位设定值时,进入雨停模式,恢复晴天模式。Rain stop mode: when the liquid level in the upstream well is lower than the rain stop liquid level setting value, the system enters rain stop mode and resumes sunny day mode.

更进一步的,还包括极限保护模式,优先级在正常模式之前,当上游井内液位达到设定的最高水位,即报警水位时,需把堰门无条件完全打开,作为对设备的极限保护,当上游井内液位达到正常排放设定液位时,退出极限保护模式,恢复正常模式。Furthermore, it also includes an extreme protection mode, which has a higher priority than the normal mode. When the liquid level in the upstream well reaches the set maximum water level, that is, the alarm water level, the weir gate must be fully opened unconditionally as an extreme protection for the equipment. When the liquid level in the upstream well reaches the normal discharge set level, the extreme protection mode is exited and the normal mode is restored.

更进一步的,还包括防倒灌模式,优先级在正常模式之前,当下游污水管液位高于上游井内液位设定高度时,闸门无条件关闭,当下游污水管液位低于上游井内液位设定高度时,退出防污水倒灌程序,恢复正常模式。Furthermore, it also includes an anti-backflow mode, which has a higher priority than the normal mode. When the liquid level in the downstream sewage pipe is higher than the set height of the liquid level in the upstream well, the gate is unconditionally closed. When the liquid level in the downstream sewage pipe is lower than the set height of the liquid level in the upstream well, the anti-sewage backflow program is exited and the normal mode is restored.

相比于现有技术,本发明具有如下有益效果:Compared with the prior art, the present invention has the following beneficial effects:

1、本发明的智能分流井截污管前装有由控制系统控制开闭的闸门,能够对通往污水处理厂的最大量进行控制,同时可以防止污水回流;1. The intelligent diversion well interception pipe of the present invention is equipped with a gate controlled by the control system to open and close, which can control the maximum amount of sewage leading to the sewage treatment plant and prevent sewage backflow;

2、智能分流井出水口前装有由控制系统控制的下开式堰门,截流高度可以智能调节,同时可以防止自然水体的倒灌;2. A downward-opening weir gate controlled by the control system is installed in front of the outlet of the intelligent diversion well. The interception height can be adjusted intelligently, and the backflow of natural water bodies can be prevented at the same time;

3、智能分流井采用水质法、时间法和水位法进行控制分流,普通的分流井只是水位控制;3. Intelligent diversion wells use water quality method, time method and water level method to control diversion, while ordinary diversion wells are only controlled by water level;

4、智能分流井可进行智能控制,智能化程度较高,优化操作,普通的分流井仅仅只是对单个的设备进行人工控制。4. Intelligent diversion wells can be intelligently controlled with a high degree of intelligence and optimized operation. Ordinary diversion wells only allow manual control of a single device.
