With the country’s vigorous promotion of clean heating in the north, clean energy heating is becoming a trend. Using clean energy for heating can not only improve the grid’s ability to consume clean energy, but also make an important contribution to reducing environmental pollution. Therefore, clean and pollution-free electric heating is currently the most important way of clean heating in northern areas. This paper takes an area in Xinjiang as an example, it not only analyzes the effect of regenerative electric heating on wind power absorption capacity, but also sorts out the current status of electric heating and related policies, which is of great significance to the promotion of electric heating in Xinjiang.

Taking urban roof as the catchment area in Xinxiang City, researching on the hydrology and water quality process of each rainfall event in storm sewer can provide the basis for effectively using urban rainfall and controlling non-point source pollution, and so on. The samples were taken to analyze the contents of SS, COD and TN. The results show that the variation trend of pollutant index SS, COD in runoff is similar and tends to be a steady value. TN decreased with the accumulation of rainfall, but rebounded before the end of rainfall. The standard deviation rate of water quality indicator is SS > COD > TN. The roof flush effect is obvious at the initial stage of runoff, and the initial runoff amount can be defined as the first 1-3mm rainfall. The correlation of SS, COD and TN is good in runoff, and measures can be taken to remove them simultaneously in controlling the runoff pollution. The runoff pollutants flow into the receiving water directly through urban drainage pipe network, and have a great effect on its water quality, especially the changes of SS and COD are the most obvious.
