[0058] Example 1A 2 Rural domestic sewage treatment facilities of O process
[0059] A method for supervising rural domestic sewage treatment facilities, comprising the following steps:
[0060] (1) Randomly select 87 rural domestic sewage treatment facilities in Jiaxing City, Zhejiang Province, sample the rural domestic sewage in the regulating pools of the 87 stations, and detect TN and NH in the samples 3 - Concentration and conductivity of N and TP; three water samples were taken in the morning, noon and night of the sampling day, and the average value of pollutant concentration and conductivity in the three water samples was taken as the final sampling result.
[0061] (2) according to the detection data of sample in step (1), carry out linear regression analysis and equation fitting, obtain conductivity and TN, NH 3 -The linear relationship between the concentrations of N and TP;
[0062] Among them, the linear regression equation is: y=ax+b; x is conductivity, y is T...

Abstract
The invention discloses a method for adjusting the water inlet load of a rural domestic sewage treatment facility. The adjusting method comprises: selecting a rural domestic sewage treatment facility,and sampling the sewage in the water inlet adjusting tank so as to detect the concentration and the conductivity of pollutants in the sample; obtaining a linear relationship between the conductivityand the pollutant concentration based on the detected data; installing a conductivity meter and a liquid level gauge in the water inlet adjusting tank of each rural domestic sewage treatment facilityto monitor the conductivity value and the water level height, and calculate the concentration and total amount of the pollutants in the water inlet regulating tank, and then determining the duration of the opening of a lift pump according to the pollutant volume load or the pollutant surface load of the sewage treatment facility to adjust the water inlet load of the rural domestic sewage treatmentfacility. According to the method for adjusting the water inlet load of the rural domestic sewage treatment facility, the water quality of the water inlet in the rural domestic sewage treatment facility is monitored and managed by measuring the conductivity of the water inlet in the treatment facility, so that the efficient adjustment of the water inlet load of the rural domestic sewage treatmentfacility is realized with the reduced monitoring costs.
Description
technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a method for adjusting the inflow load of rural domestic sewage treatment facilities. Background technique [0002] In recent years, the number of rural domestic sewage treatment facilities in my country has increased dramatically. Taking Zhejiang as an example, rural domestic sewage treatment facilities have basically achieved full coverage of villages and households. There can be hundreds of facilities in a county, and the geographical location is highly dispersed. These facilities are large in number and large in area, and currently mainly rely on manual operation and maintenance management; while using the national standard method to monitor water quality indicators, the cost of sampling and water quality testing during the supervision process is high, the cycle is long, and the workload is heavy. Not only is it difficult to real-time In addition, it is difficul...
