Zhangzhou Ltd using faggiolati pump station

The situation

Zhangzhou has a well-developed river system with a nw-and nne-trending river system. The main stream is usually perpendicular to the mountain trend, and the tributaries are parallel to the mountain trend. Form a lattice network of water systems. The river originates in the territory, is the mountain stream type outflow river. It is rich in water, stable in annual runoff, seasonal change is very big, high in flood period, low in orange period. There are 11 rivers covering an area of more than 100 square kilometers in the city. The geology of the Zhangzhou Sea is bounded by the Binhai Fault Zone, which runs in a northeasterly direction through the brothers island and is roughly parallel to the coastline. The north side is the continental extension and the south side is the South China Sea subplate. Zhangzhou is a tropical Southern Ocean monsoon, with high mountains in the north to protect it from cold currents, and oceans in the south to regulate its location at lower latitudes. Near the Tropic of Cancer, the climate is warm and the rainfall is abundant. However, the interannual and seasonal variation of rainfall. The drought and flood disasters occurred alternately, the geographical distribution was not uniform, the rainfall in mountainous areas was more, the coast was less, and the typhoon activities were frequent in summer. Flood control and drainage and sewage collection are important work of municipal work, which is related to people's lives and survival.

The solution

The geology of Zhangzhou;s interior is complicated by orogeny of the Indosinian-yan Mountains-himalayan period, the overall geological structure is controlled by the ne-trending cathaysian, ne-trending neocathaysian and nnw-trending Taiyishan types. The sedimentary rocks in the north are mainly fold, then fault, the magmatic rocks in the middle and south are mainly fault, then fold, and the mechanical properties are mainly compressive-torsional. The mountainous area is composed mainly of Mesozoic volcanic rock and Yan Mountains granite, which is hard in lithology and has strong resistance to erosion. Most of the rocks are weathered and cracked along the joints, and the overall water quality is high in sand content, the FAGGIOLATI integrated pump station, with its expertise in this area, can help customers to play a good role in centralized treatment of rainwater and sewage. After on-site investigation and calculation, FACHAOLATI technicians designed an integrated prefabricated sewage pumping station with a diameter of 2.5 m, a total height of 8.5 m and a daily treatment capacity of 10,000 m3/d, each pumping station is equipped with 3 phacoolatti submersible sewage pumps. The silting prevention base of CFD is adopted at the bottom of the wellbore, which can reduce the silting at the bottom of the wellbore, and greatly reduce the difficulty and cost of later maintenance.
