A method for controlling Cladoflagellates in channel-type drinking water sources based on scheduling and disposal

Abstract

The invention discloses a method for controlling and removing cladophora in a channel type drinking water resource area based on scheduling and disposal, and relates to the technical field of channelwater quality guarantee. The method has the advantages that by determining the key controlling and removing position of cladophora in a channel and the target scheduling flow rate, a gate scheduling plan and a fishing device disposal plan are made; by applying the gate scheduling, the hydrodynamic survival environment conditions of the cladophora can be changed, the flow rate at the key controlling and removing position of cladophora in the channel is effectively regulated and controlled, and the cladophora at both side walls can be flushed and cleaned in a centralized way; by combining with the disposal measures, the cladophora at the side walls of the channel can be cleaned in a centralized, efficient and harmless way in shorter time, and the influence to the water quality of the channeltype drinking water source area by the sustained falling of cladophora in growth seasons at present is decreased.

Description

technical field [0001] The invention relates to the technical field of channel water quality assurance, in particular to a method for controlling and removing Cladophora in channel-type drinking water sources based on scheduling and disposal. Background technique [0002] Cladophytes are widely distributed and are common in rivers, channels, lakes and reservoirs in my country. In the spring and autumn seasons, the bristle algae on the side walls of the water delivery channel will explode, and its normal growth and death may lead to long-term persistence and massive shedding of algae clusters. It will cause blockage of the water intake, and affect the water quality and daily water supply of channel-type drinking water sources. [0003] At present, most of the measures to control benthic algae, especially Cladophora, are two methods at home and abroad, namely physical method and chemical method. The main chemical methods include the use of herbicides or biological products t...

Problems solved by technology

[0004] The physical method is mainly to manually salvage the raw Cladophora. However, the channel-type drinking water sources have long lines and the period of continuous shedding of algae clusters often lasts for more than two months. The workload of traditional physical methods is relatively large, and the disposal cost increases accordingly.

[0005] Facing the continuous and massive shedding of Cladophora on both sides of the water delivery channel in spring and autumn, there is a lack of research on the control and dispatching of the water delivery channel sluice group combined with disposal measures to realize the control of Cladoflagellate in channel-type drinking water sources.
