Recently, the first sludge disposal center pilot project in Xihu District has been basically completed, and the equipment is being installed, installed and commissioned. It is expected to be put into trial operation before the end of the year.

The center is located in Shanlian Village, Sandun Town. Through organic waste collection, mechanical dehydration, and high-temperature aerobic composting, nitrogen and phosphorus organic fertilizers are produced, so that organic wastes generated during the treatment of rural domestic sewage can be effectively disposed of. "According to estimates, the Sandun Township Sludge Disposal Center can treat 3 tons of sludge per day and produce about 2 tons of organic fertilizer." The relevant person in charge of the Construction Bureau of Xihu District introduced.

According to reports, as early as 2014, Xihu District has been coordinating rural sewage treatment work. At present, most of the rural sewage treatment facilities are not equipped with sludge treatment and disposal systems. In addition, due to the inherent rural living habits, biomass waste generated during rice washing and vegetable washing will also enter the wastewater treatment system.

"In the past, these wastes were mainly landfilled or discarded in trash cans, because they were not treated, and they could smell the odor as long as they passed. Especially in the summer, the residents nearby were suffering." The treatment and disposal of mud and solid waste is still blank in the field of rural sewage treatment. It is urgent to effectively use the resources in these organic wastes.

Xihu District has also built another sludge disposal center in Shuangpu area. The equipment is expected to be installed before the end of November and will be completed within the year.

It is understood that there are currently 175 rural domestic sewage treatment facilities in Xihu District, involving 31 towns and 31 villages (communities), with an average treatment scale of 40.23 tons / day. At present, 114 facilities are included in the long-term operation and maintenance, and the remaining 61 facilities are implementing improvement and improvement projects. Within this year, 54 rural domestic sewage facilities will be upgraded.

This year, the Xihu District also launched a backwater pilot project at three facilities terminals in Hebei Tang, Hualian No.1, and Southwest Area around the city. Flower fields, roadside greening and small parks have basically achieved zero straight drainage.
