Through the biofilm growing and trial(operation) of the integrated treatment facilities, the parameters of the reclaimed water can reach: COD_(Cr)=11.8mg/L,BOD_5=3.8 mg/L,SS=6 mg/L,pH=7.67,coli colony ≤3/L,All of the parameters meet the relevant national standards for the supply water of circulation cooling water.
According to the water shortage status in Xining City,the near and long-term capacities of wastewater reuse are determined as 6.2×10~4 m~3/d and 12.8×10~4 m~3/d respectively,and the recommended water quality of reclaimed water is given;
Based on the drainage status analyses and the layout of wastewater treatment plant in Baoji city,potential users of recycled water is analyzed and the water requirement calculated,by using the linear programming model to optimize the recycled water potential in Baoji.
The deposition effects of the total phosphorous(TP) and phosphate(PO_(4)-P)in TEDA Reuse Water & Landscape River are studied,and the sedimentation reason of TP,PO_(4)-P are analyzed,then the settling curve of TP and PO_(4)-P is drawn in recycled water which is changed with time.
currently,the utilization rate of the recycled water accounts to 37% of the total water use in the city and the water is mainly for industrial use of cooling system,irrigated agriculture,third industry and gardening.
Through the analysis of the practical water quality for a eco-restored project of landscape river with reused water from highly salty river water,the water purification effect and the salt content dynamic changing law in the river in saline-alkali land were studied.
When low irrigation quantity , the sewage, the dilution sewage and reused water processing compare with the control, separately increases production 12.71%,9.57% and 1.14% When high irrigation quantity, the sewage, the dilution sewage and reused water processing compare with the control,separately increases production 12.22%, 5.05% and 2.12%.
Through the barrel experiment , This article first time comprehensively studied under the sewage, 1/2 sewage + 1/2 clear water, reused water and the clear water irrigation condition, the change of starch, protein, nitrogen, phosphorus, potassium content in winter wheat grain, as well as the influence of wheat grain yield and grain heavy metal residual with different water quality irrigation.
The result indicates: When the irrigation quantity is same , four different water quality processing, the relationship of the wheat grain crude protein content is sewage >1/2 sewage +1/2 clear water > reused water > clear water, also the crude protein content must obviously be higher than other water quality processing in sewage;
Response ofRuppia maritima to the reclaimed wastewater in coastal artificial landscape river
Control of emitter clogging in drip irrigation with reclaimed wastewater
In this study, chemical factors controlling AOB activity, diversity, and composition in a turfgrass-covered aridisol irrigated with groundwater, Colorado River water, or reclaimed wastewater were examined.
The model results in a comprehensive management methodology for optimizing water resources within an industrial park, seeking potential water reuse among industries, and incorporating the size and cost of reclaimed wastewater delivery systems.
