10、asurement of a flow rate and the test for properties of effluents discharged from coal preparation plant. The effluents from coal preparation plant contain mine water and ef- fluents from ore accumulation places. Remarks : 2 General matter 2.1 described in JIS K 0050. Reagents, filter papers and too
11、ls Reagents, filter papers and tools are as 2.2 Sample The sample given in this testing method indicates water sampled for carrying out various tests, the test water indicates water fractionally taken for car- rying out each test. The test water and the sample shall represent the properties of raw w
12、ater. The sample is put into a sample vessel which is cleaned and then sufficiently washed by raw water, filled almost into therein, hermetically sealed, transported to a test room or a test site. For each test, a suitable amount of test water is fraction- ally sampled from the sample, and quickly t

17、 variation of operating condition of coal prepara- tion plant, the condition of each machine kind in coal preparation system, and change of the used water amount and the like. Therefore, for the sampling, raw water likely to conform completely to the test purpose by sufficiently understanding the pu
18、rpose of the sampling test shall be sampled as the sample. For the method for sampling, in order to represent properties of raw water to the best according to each condition, if necessary, the direction and shape of the flow are changed (a head is applied to the flow and the like), and further the s
19、ample is taken over several times. Since the place, time, method and the like of sampling some times are varied according to the purpose of the test, the condition, place, date, time, method, the operating condition of coal preparation plant and the like are clearly described. 2.2.2 Sampling amount
20、The sampling amount shall be as follows. Screen analysis 10 I or over Settling test 10 E or over Other tests 2 1 or over 2.2.3 Sample vessel For a sample vessel, a polyethylene bottle or a glass bottle is used. The sample vessel, in order to prevent mixing of pollutant and the like, is her- meticall
21、y sealed by the material which is free from generation of contamination and pollution. For the test vessel, that which is preliminarily sufficiently cleaned, is washed five or more times with raw water, is used. 2.2.4 Transportation and preservation of sample A sample, while properties of raw water
22、are kept, is transported to a test room, and quickly tested. For trans- portation and preservation of the sample, cares shall be sufficiently taken to pre- vent damage and deterioration of the sample in the way of transportation and preservation. Cares shall be also taken for the place where it is p
23、reserved. 2.2.5 Observation, measurement and recording contents on sampling For observations to be carried out on the site in sampling, recordable items such as the position of a sampling place, date, time, weather (on the day and the previous day) and the like are observed. Atmospheric temperature
24、and water temperature are accurately measured, and pH also is measured on the site as much as possible. An outline of other conditions (an odor, a color of suspension and its gross amount, settling state and the like) is recorded by measuring. Further, the operating condi- tion of coal preparation p
25、lant on the day is recorded. 2.3 Marking of results (i) In the case of marking test results, when two or more test methods exist, either method to be applied is clearly stated. Test results shall be generally marked to two significant figures (the third figure is rounded off in accordance with JIS Z
26、 8401) within the determination range.

The channel of a weir comprises a water level measuring part, flow straight- ening part and a running water introducing part from the weir to the up- per stream (see Fig. i). T
34、he number of perforated plates of the apparatus for straightening the flow is made at least two pieces, as possible four pieces, and installed at a right angle and vertically to the running water at equal intervals in the flow straightening part.

35、rt for running water may be omitted in the case where the channel on the upper stream is larger than the width, depth and the like of the channel. The volume of water kept in store is preferably as much as possible. (2) Sheathing board (a) The material of a sheathing board is a steel plate of 1 3 mm
36、 thickness. (b) The edge of the sheathing board, as given in Fig. 2, forms a plane normal to an inner face of the sheathing board within approximately 2 mrn from an inside of the sheathing board, and forms a slant face of approximately 45“ toward an outside therefrom. +Approx. 2 mm Fig. 2 (c) The ed
37、ge inside the sheathing board forms a straight line, and finished by a file to be made the corners sharp and not to have a roundness. (d) The inner face of the sheathing board is a plane, and especially the part within 100 mm from the edge is finished as smooth as possible. For the sheathing board,
38、so that it is not bent outside by water pressure of running water, a reinforcing material is fitted, as given in Fig. 3, 2 3 mm separated from the notch bottom point of the outside face of the sheathing board (right triangular weir) or from the lower edge of the notch (square weir).
