Abstract
The invention discloses a sampling method for detecting the effluent quality of a sludge thickener, which relates to a sludge thickener, a sludge balancing pool and a sludge feeding pipe which is connected with a sludge concentrate and a sludge balancing pool. The sampling method is characterized by at least comprising the following steps of: arranging a circulation bin in a sludge balancing pool and communicating the circulation bin with the water outlet of a sludge feeding pipe; arranging an overflow port on the upper part of the circulation bin; and arranging an input-type water quality detector in the circulation bin to detect a sample. The sampling method has the advantages that the defect of a traditional pipeline-type arrangement mode can be overcome, an outdoor instrument well is not required to be arranged independently, the difficulty and workload for cleaning and maintaining instruments can be reduced, and the calibration, cleaning, maintenance and replacement of detecting instruments can be facilitated.
Description
Technical field
The invention belongs to water-treatment technology field, be specifically related to a kind of sampling method for the detection of sludge thickener effluent quality.
Background technology
Water purification plant's spoil disposal water technology generally is comprised of structures such as spoil disposal water equalizing tank, concentration basin, mud counterbalance cell and dehydration machine rooms.For the equipment of controlling concentration basin opens and closes and operational mode, need to be to the detection of taking a sample of concentration basin effluent quality.During lower than set(ting)value, namely close the concentration basin effluent water pump when the concentration basin effluent quality parameter that detects.
During routine in the past arranged, the mode of generally taking duct type water quality detection gauge sensor is set on pipeline between concentration basin and mud counterbalance cell gathered water quality data, namely adopts the duct type mounting means.Adopt the shortcoming of this type of mode to be: need to do outdoor instrument well, high to the requirement of instrument degree of protection, bring many difficulties for simultaneously demarcation, cleaning, maintenance and the replacing of instrument.
Summary of the invention
The objective of the invention is according to above-mentioned the deficiencies in the prior art part, a kind of sampling method for the detection of sludge thickener effluent quality is provided, this sampling method arranges the circulation storehouse and lays the throw-in type water quality testing meter by the mud pipe mouth of pipe place advanced in the mud counterbalance cell, detects the purpose of sludge thickener effluent quality to reach sampling.
The object of the invention realizes being completed by following technical scheme:
A kind of sampling method for the detection of sludge thickener effluent quality, relate to sludge thickener, mud counterbalance cell and connect described sludge thickener and described mud counterbalance cell advance the mud pipe, it is characterized in that described sampling method comprises the steps: to arrange a circulation storehouse at least in described mud counterbalance cell, and described circulation storehouse is communicated with the described water outlet that advances the mud pipe; On top, described circulation storehouse, spillway is set; Laying the throw-in type water quality testing meter in described circulation storehouse detects in order to sampling.
The method to set up in described circulation storehouse is: below described on described mud counterbalance cell pool wall advances the mud pipe mouth of pipe, buttress is set, described circulation storehouse is arranged on described buttress top and fits with described mud counterbalance cell pool wall.
The end absolute altitude in described circulation storehouse is set to consistent with the described absolute altitude that advances at the bottom of mud pipe pipe.
High being set to lower than the highest operating water level 0.3～0.5m of described mud counterbalance cell of top mark with described circulation storehouse.
Described circulation storehouse discharge section area is not more than described long-pending 5 times of mud tube section that advance.
Advantage of the present invention is, solved the deficiency of conventional pipelines formula mounting means, need not to arrange separately more outdoor instrument well, also reduced difficulty and the workload of instrument cleaning, maintenance simultaneously, brings convenience for demarcation, cleaning, maintenance and the replacing of measuring instrument.
Description of drawings
Fig. 1 is the structural representation of sampling unit in the present invention.
Embodiment
Feature of the present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
As Fig. 1, in figure, mark 1-5 is respectively: throw-in type water quality testing meter 1, mud counterbalance cell 2, enter mud pipe 3, buttress 4, circulation storehouse 5.
Embodiment: as shown in Figure 1, the present embodiment is specifically related to the sampling method that a kind of sludge thickener effluent quality detects.General water purification plant spoil disposal water technology is comprised of structures such as spoil disposal water equalizing tank, sludge thickener, mud counterbalance cell 2 and dehydration machine rooms, be provided with between sludge thickener and mud counterbalance cell 2 be connected both advance mud pipe 3, muddy water enters mud counterbalance cell 2 from sludge thickener through advancing mud pipe 3.For the equipment of controlling sludge thickener opens and closes and operational mode, need to be to the detection of taking a sample of sludge thickener effluent quality.Sampling method in the present embodiment is specially:
1. at first at casting concrete (or brick) buttress 4 below mud pipe 3 mouths of pipe that advances on mud counterbalance cell 2 pool walls;
2. the fixing storehouse 5 of circulating is installed on buttress 4 thereafter, stainless steel rectangular pipe or semicircular pipe can be adopted in circulation storehouse 5, the pool wall that fits in mud counterbalance cell 2 is installed, its bottom is connected with the mouth of pipe that advances mud pipe 3, the end absolute altitude in circulation storehouse 5 flushes with the absolute altitude that enters the mud pipe 3 pipe end, and the top mark in circulation storehouse 5 is just in the highest operating water level 0.3～0.5m of mud counterbalance cell 2; Cause alluvial for the interior flow velocity in storehouse 5 that prevents from circulating is too low simultaneously, its discharge section area is not more than into 5 times of mud pipe 3 sectional areas, and the water-carrying section in circulation storehouse is its cross section;
3. lay throw-in type water quality testing meter 1 in circulation in storehouse 5 at last, detect the sludge thickener effluent quality in order to sampling, during lower than set(ting)value, close immediately the sludge thickener effluent water pump when the sludge thickener effluent quality parameter that detects.
The present embodiment is with respect to the beneficial effect of prior art: by the storehouse 5 of circulating is set in order to go along with sb. to guard him at the water outlet that advances mud pipe 3, can reach equally the purpose that detects the sludge thickener effluent quality, solved simultaneously the deficiency of conventional pipelines formula mounting means, need not to arrange separately more outdoor instrument well, also reduced difficulty and the workload of instrument cleaning, maintenance, brought convenience for demarcation, cleaning, maintenance and the replacing of measuring instrument.
