Embodiment Construction
[0072] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The description of the exemplary embodiments is for the purpose of illustration only, and in no way limits the invention and its application or usage.
[0073] During long-term use, constructed wetlands are prone to matrix clogging, which significantly reduces the treatment efficiency of constructed wetlands. In the prior art, when the artificial wetland is unblocked, all the fillers can only be dug out and washed, refilled, and replanted with aquatic plants, which requires a huge amount of work, a serious waste of manpower and material resources, and low work efficiency. The present invention determines the pollution clogging situation of the constructed wetland by setting the distribution channel at the water inlet end of the constructed wetland, detecting the liquid level value of the distribution channel and comparing it with a certain thresh...

The invention discloses a method and a system for the online automatic clean-up of constructed wetlands. The method comprises the following steps: acquiring a liquid level value of a water distributing channel arranged at the water inlet end of a constructed wetland, if the liquid level value is greater than a preset liquid level threshold value, determining that the constructed wetland has a sewage blocking phenomenon, and determining a first aeration quantity according to the area of the constructed wetland required to be cleaned up; closing a water inlet valve on a water distributing channel and a water outlet valve arranged on a water tapering channel at the water outlet end of the constructed wetland, opening an aeration unit, and carrying out online aerated clean-up on the constructed wetland according to the first aeration quantity; when the clean-up time reaches a preset first clean-up time threshold value, closing the aeration unit, opening the water inlet valve and the water outlet valve arranged on the water tapering channel, and discharging blocked pollutions out of the constructed wetland; and when the pollution discharge time reaches a preset pollution discharge time threshold value, closing a blowdown valve, and opening the water outlet valve. According to the invention, the online automatic clean-up of blocked pollutions in constructed wetlands can be realized, the method and system disclosed by the invention are rapid and convenient, and low in cost.
Description
technical field [0001] The invention relates to the technical field of water treatment and purification, in particular to a method and system for automatically unclogging a constructed wetland online. Background technique [0002] The technical background related to the present invention will be described below, but these descriptions do not necessarily constitute the prior art of the present invention. [0003] Constructed wetland refers to artificially building pools or trenches, laying anti-seepage water-proof layer on the ground, filling a certain depth of matrix layer, planting aquatic plants, and utilizing the physical, chemical and biological synergies of matrix, plants, and microorganisms to make wetlands wetlands. Dirty (waste) water is purified. According to the flow mode, constructed wetlands are divided into surface flow constructed wetlands, horizontal subsurface flow constructed wetlands and vertical subsurface flow constructed wetlands. [0004] Due to the a...
