1. Project background Hehe Town Sewage Plant is located in Hehe Town, Binzhou City, Shandong Province, with a sewage treatment capacity of 3,000 tons per day. Construction unit Shandong Narui Environmental Protection Technology Co., Ltd. 2. Sewage from the process flow enters the coarse grid from the external pipeline, and enters the fine grid through the lifting pump after first-level screening. After being screened by a fine grid, the sewage enters the cyclone grit sink, and after aeration and sand-water separation, the sewage enters the homogeneous tank. The sewage in the homogenization tank is fully mixed by the push pump and then enters the anaerobic tank, anoxic tank and aerobic tank in sequence, and finally enters the secondary grit tank. The effluent from the secondary sedimentation tank enters the flocculation sedimentation tank, and PAC and PAM are added to the tank for flocculation

Dongqian Lake is a lake in Ningbo City, Zhejiang Province, China. It is 8.5 kilometers long from north to south, 4.5 kilometers wide from east to west, and has a water area of 19.14 square kilometers. It is the largest natural lake in Zhejiang Province and the main source of drinking water and irrigation in downtown Ningbo. The Lake District and the surrounding area are under the jurisdiction of Dongqianhu Town, Yinzhou District, Ningbo City, and are currently hosted by Ningbo Dongqianhu Tourism Resort. The Dongqian Lake online water environment monitoring and early warning system contracted by our company this time monitors the water quality and meteorological conditions of Dongqian Lake in real time, analyzes the water quality changes of Dongqian Lake, and provides protection for the water environment of Dongqian Lake. The project includes a buoy station,

Xiamen City is one of the first batch of national “sponge cities” to build pilot cities, and monitoring the water quality of “sponge bodies” (natural water systems composed of rivers, lakes, ponds, and ditches) is one of the key tasks. The “National Sponge City Online Monitoring Demonstration Site” jointly constructed by our company, Xiamen Haicang District Government and Huaqiao University Municipal and Environmental Engineering Research Institute is located in Haicang District, Xiamen City. It adopts a container-type mobile monitoring room. The monitoring parameters include: There are 9 parameters: PH, dissolved oxygen, conductivity, turbidity, COD, ammonia nitrogen, total nitrogen, and total phosphorus. After several days of installation and commissioning, the system has been put into operation. These water quality monitoring data

In July 2016, Fuzhou Fuguang Water Technology Co., Ltd. participated in the bidding project of the automatic monitoring of water quality in Jinghai District, Tianjin Environmental Protection Bureau, and won the bid. The main construction content includes the construction of three water quality automatic stations including Tuanbo Reservoir, Daqinghe Taitou Section and Tuanpiao Bridge Section. Each site contains a five-parameter analyzer, a permanganate index analyzer, an ammonia nitrogen online analyzer, a total phosphorus online analyzer, a CODcr online analyzer, automatic sampling, an auxiliary system, a water collection and distribution pretreatment unit, control and data transmission Unit, video monitoring system, access control, power environment monitoring system, station building. 2017 1
