Yiyang promotes the construction of sewage treatment facilities in villages and towns in an all-round way
The red roof, the pale yellow walls, the garden is full of flowers and plants.Accompanied by the low-decibel operation of the sewage treatment system, a clear stream happily rushed to the vast fields.On September 24, the reporter inspected the operation of the newly-built sewage treatment plants in Bijiashan Township, Quanjiaohe Town, and Oujiangcha Town with the staff of the Housing and Construction Department of Heshan District, and witnessed the gratifying picture of the sewage becoming clearer.
There are a total of 10 township sewage treatment plants in Heshan District. At present, 9 township sewage treatment plants including Henglongqiao Town, Xinshidu Town and Lanxi Town have completed their construction and started operation smoothly.The only remaining Bazishao Town Sewage Treatment Plant has also entered the stage of equipment installation and commissioning and is expected to reach operating conditions by the end of September.
Since 2017, our city has followed the province's three-year action requirements for the construction of sewage treatment facilities in key towns, focusing on shortcomings, planning from a high starting point, building strict standards, and promoting the construction of sewage treatment facilities in towns in an all-round way.At present, the city has invested a total of 1.48 billion yuan, 61 towns and villages have built (connected) sewage treatment facilities, 490 kilometers of supporting pipe network, daily treatment capacity of 115,000 tons, fully implemented the first-level A standard of effluent, and completed the construction of sewage treatment facilities. 78.2%.
To vigorously promote the full coverage of sewage treatment facilities in towns and villages, our city has established a promotion mechanism of “municipal-level leadership, county-city main battles, and township-level main forces”. All organizational townships are rolled out.Up to now, in accordance with the requirements of “full interception, full collection, and full treatment”, our city has completed 8 county (district, city) township drainage (sewage) special plans, organized 7 batches of provincial technical review, and reviewed township sewage treatment There are 78 special plans to ensure the rationality and scientificity of the plans.
During the construction process, emphasis was placed on economic application, and no one-step implementation was required.Our city focuses on the overall planning of urban and rural areas, achieves the sharing of facilities, encourages the extension of the urban pipeline network to the surrounding towns and villages, and promotes the collaborative processing of built-up areas and suburban villages.Establish the city's "one game of chess" ideology, deepen reform and innovation, do a good job of undertaking and delegating relevant approval authority in a timely manner, and optimize the preliminary approval procedures for projects to ensure the smooth progress of project construction.
Promote the construction of sewage treatment facilities according to local policies.In view of the typical landforms of mountainous areas, hills and lake plains in our city, the county (district, city) independently chooses centralized or decentralized sewage treatment methods.Considering factors such as population density, topography, township scale and economic affordability, in towns with flat terrain and large populations, choose A2O+ advanced treatment, integrated MBR membrane and other technologies to build sewage treatment plants; For towns and residential areas with large fluctuations, select PE fixed-bed biofilm, MABR and other technologies to build decentralized sewage treatment stations to achieve "unified planning and fragmented implementation", transform large pipe networks into small pipe networks, and reduce pipe network construction cost.In the site selection, combined with the treatment of irregular garbage dumps and black and odorous water bodies, some old garbage dumps, odorous ponds, and waste land in the built-up areas of towns and towns will be used as the site for the construction of sewage treatment facilities to realize the reuse of waste land.While saving land, it also beautifies the environment.
The construction and management of sewage treatment facilities depend on construction for one third and operations for seven.In order to implement the responsibilities of the operating and supervisory entities, and ensure that one is built and one is operated, our city actively explores the establishment of a management mechanism for one-party operation, ecological environment, housing construction, and township government three-party supervision, as well as payment for sewage treatment according to the treatment volume and water quality compliance. Fee payment mechanism.At the same time, explore smart online monitoring mechanisms.At the municipal level, develop the "Yiyang Smart Housing and Construction" platform to integrate the basic data, construction projects, and operation status of township sewage treatment plants into the platform to improve the information and technological management of sewage treatment.At the county level, establish a smart online monitoring center to uniformly monitor the operation data of sewage treatment facilities online to achieve "unmanned" duty to ensure safe and orderly operation.Through effective exploration, related work has gradually entered a virtuous circle.
